3 1. presentation of the VIP300 Mitop VIP300 - simplified wiring scheme - t t> t>> 1,2 10 I>> - phase or earth fault curves - I self-powered protective relay n The VIP300 relay is designed for use in distribution networks. It may be used as MV/LV transformer protection, protection at the incoming point of industrial installations, and also as branch feeder protection. n The VIP300 provides protection against phase-to-phase faults and earth faults. The choice of tripping curves and the multiple settings allow it to be used in a wide variety of discrimination plans. The VIP300 is a self-powered relay, energized by the current sensors; it does not require any auxiliary source. It actuates a Mitop release. phase protection The phase protection has two separately adjustable settings: n the low setting may be chosen with definite time or IDMT. The IDMT curves are in compliance with the IEC standard. They are of the standard inverse, very inverse and extremely inverse types. The low setting may also be used with the RI curve. n the high setting is of the definite time type. earth protection The earth fault protection operates by residual current measurement: it uses the sum of the sensor secondary currents. Like phase protection, earth protection has two separately adjustable settings. LL and LH models There are two models of the VIP300: VIP300LL and VIP300LH, They differ with respect to : n operating range. Refer to the chapter entitled "choice of sensors and operating ranges". n the VIP300LH has a table for setting "equivalent time multiplier" conversion on the front. sensors In order for the specified performances to be obtained, the VIP300 relay must be used with the following current transformers: n CRa and CRb sensors: (for RM6s 1998 and later). n CSa and CSb sensors of the SFset circuit breaker. The CSa and CSb sensors have the same number of secondary turns as the CRa and CRb sensors respectively. n 200/1 and 800/1 sensors of the Ringmaster: description n The VIP300 relay is mounted in a polycarbonate injected casing which protects it against dripping water and dusty environments. The front is protected by a transparent cover fitted with a sealing joint. The cover may be lead-sealed to prohibit access to the settings. n Rotating selector switches are used for setting. The phase setting current and earth fault setting current are set in amperes. This means that the scale on the front must be adapted to suit the sensor used. This is done by positioning a "setting scale label" on the relay at the time of assembly. n Connections are made on the back using fast-on clips. indication Two indicators indicate the origin of tripping (phase or earth). They stay in position after a break in the relay power supply. Two LEDs (phase and earth) indicate that the low setting has been overrun and that the time delay is running. technical manual VIP300 3

6 2. use and settings (cont d) phase protection 1. phase protection setting zone All the information concerning phase protection is grouped together in the dark zone of the upper half of the front face. 2. setting overrun indicator When the red indicator blinks, it means that the phase protection low setting time delay is running. When this is the case, if the current does not decrease, the relay will trip. n for IDMT curves (SI, VI, EI), the LED lights up when the current is greater than 1.2 times the setting current. n for the IDMT curve (RI), it lights up when the current is greater than the setting. n for the definite time curve DT, it lights up when the low setting is overrun. F also refer to "indicator reset button". 3. trip indicator It is normally black and turns yellow to indicate that the phase protection has given a tripping order. It stays in the same status, even when the relay is no longer energized. 4. choice of setting current The setting current setting range depends on the sensor and range used: the selector switch scale should be adapted to suit the sensor and range using the setting scale label. F also refer to "choice of sensors and operating ranges" chapter. 6. choice of low setting I> The setting is a multiple of the setting current. It is only active for definite time settings (selector switch 5 set to DT). If the tripping curve is selected with IDMT (selector switch 5 set to RI, SI, VI, EI), the selector switch has no effect. 7. setting of low setting time delay t>. n If the tripping curve is of the definite time (DT) type, the selector switch sets the low setting time delay. n If the curve is of the IDMT type (RI, SI, VI, EI), the value displayed is the tripping time for a phase current equal to 10 times the setting current. 8. low setting time delay multiplying factor. In the x10 position, the time delay displayed on selector switch 7 is multiplied by setting of high setting I>>. The high setting is chosen as a multiple of the setting current. In the "off" position, the high setting is disabled. 10. setting of high setting time delay t>>. The time delay is set directly in seconds. 5. choice of type of low setting curve DT: definite time SI: inverse time VI: very inverse time EI: extremely inverse time RI: specific curve off: low setting is disabled. 6 technical manual VIP300

7 2. use and settings (cont d) earth protection The setting principle is the same as for phase protection. 11. earth protection setting zone The earth protection settings are grouped together in the dark zone of the lower half of the front face. 12. setting overrun indicator When this indicator blinks, it means that the earth protection low setting time delay is running. When this is the case, if the current does not decrease, the relay will trip. n for IDMT curves (SI, VI, EI), the LED lights up when the current is greater than 1.2 times the setting current Ios. n for the IDMT curve (RI), it lights up when the current is greater than the Ios setting. n for the definite time curve DT, it lights up when the low setting is overrun. F for the cases above, the LED only lights up when a phase current is greater than the minimum operating current. F also refer to "indicator reset button". 13. trip indicator It is normally black and turns yellow to indicate that the phase protection has given a tripping order. It stays in the same status, even when the relay is no longer energized. 14. choice of setting current Ios This is the maximum residual current that can flow in the network without the protection being triggered. The Ios current setting range depends on the sensor and range used: the selector switch scale should be adapted to suit the sensor and range using the setting scale label. F also refer to "choice of sensors and operating ranges" chapter. 15. choice of type of low setting curve DT: definite time SI: inverse time VI: very inverse time EI: extremely inverse time RI: specific curve off: low setting is disabled. 16. choice of low setting Io> The setting is a multiple of the setting current. It is only active for definite time settings (selector switch 15 set to DT). If the tripping curve is selected with IDMT (selector switch 15 set to RI, SI, VI, EI), the selector switch has no effect. 17. setting of low setting time delay to>. n If the tripping curve is of the definite time (DT) type, the selector switch sets the low setting time delay n If the curve is of the IDMT type (RI, SI, VI, EI), the value displayed is the tripping time for an earth current equal to 10 times the setting current. 18. low setting time delay multiplying factor. In the x10 position, the time delay displayed on selector switch 17 is multiplied by setting of high setting Io>>. The high setting is chosen as a multiple of the setting current Ios. In the "off" position, the high setting is disabled. 10. setting of high setting time delay t>>. The time delay is set directly in seconds. technical manual VIP300 7

The label indicates the scales for the phase setting current and earth protection setting current. It is inserted, from the top, behind the transparent part of the front face. n each VIP300 comes with a set of labels. Install the label that matches: - the type of sensor used - the VIP300 model - the range used n each setting scale label matches a sensor and is printed on both sides for each of the 2 ranges. The label may therefore be turned around if the VIP300 range is changed during the service life of the installation. F also refer to "assembly" chapter. b. sensor and range indication The text is printed on the setting scale label. When the label is installed in the slot, the text is hidden by an opaque zone. It is not visible to the user. c. indicator reset button The button is accessible when the transparent cover is closed. When the button is pressed, 2 actions are triggered: n it resets (black position) the 2 phase and earth trip indicators. When the relay is no longer energized, it is still possible to reset the indicators for about 48 hours. After that time, they may be reset after the VAP6 is plugged in. n it triggers the lighting up of the 2 red LEDs (about 3 sec). This indicates that: - the relay is energized. The indicator lights up when the current is greater than the minimum operating current. - relay self-testing results are OK. If one of the two conditions is not met, the indicators do not light up. This function may be used to carry out a basic relay operation test. d. minimum operating current The minimum operating current is the phase current required for the relay to be energized and operational. It is printed on each setting scale label. The value given on the setting scale label is the single-phase rms minimum operating current. The minimum operating current is always the lowest setting current setting. F note regarding minimum operating current: The VIP300 does not operate below the minimum operating current level. As a result, if the earth protections are set below the minimum operating current, they will only take effect when there is phase current greater than or equal to the minimum operating current. e. VAP6 test plug The test plug is exclusively designed for connection of the VAP6 which is used for fast, simplified relay testing. The operation may be carried out while the relay is operating since the VAP6 and VIP300 provide the possibility of testing with inhibition of circuit breaker tripping. F also refer to the "testing of the VIP300 and use of the VAP6" chapter. - testing of the VIP300 using the VAP6-8 technical manual VIP300

Value given for three-phase VIP300 power supply. For single-phase operation, the accuracy range is ± 10% or 0/+4A. For the low setting, this does not generally represent a real operating situation. However, it may occur during injection testing carried out with single-phase. The error is mainly due to the nonlinearity of the sensors and VIP300 input transformers with weak current, the inaccuracy being accentuated when the relay is only supplied by one phase. 2. The accuracy is indicated for a fault that occurs when the VIP300 is already supplied by the current let through by the circuit breaker. The accuracy is indicated for sinusoidal current. In the event of closing while a fault is present, the tripping time may be extended by: +30 ms at ms from 2 to ms above Generally speaking, the accuracy ranges of earth protection times and settings are indicated for when the VIP300 is supplied by current that is greater than or equal to the minimum operating current. The measurement of a setting for earth protection with single-phase supply is therefore not significant if the setting is lower than the minimum operating current. 4. Value given for three-phase VIP300 supply. For single-phase testing, the accuracy is ± 10% or 0/+4A. For the low setting, this may occur when the earth protection is tested with single-phase supply, and no supply by the other phases. 5. In the following specific conditions: - VIP300LL - with CRa sensor - wiring to x1 range - if Ios < 8A - if phase current < 20A the setting and time delay characteristics are: - low settings: ±10% 0/+4A - class not specified 6. Not applicable to test plug 7. Accuracy ± 10% or ± 1.5A. The value indicates the guaranteed minimum operating current for singlephase operation. With three-phase oepration, it may be less than the value indicated. 8. The tripping times indicated do not include the mitop response time. Its tripping time depends on its mechanical load (for no load, its tripping time is less than 5 ms) 18 technical manual VIP300

The test can be carried out in the following two cases: - the VIP300 is already supplied by the sensors. - the VIP300 is not supplied. In this case, the VAP6 batteries supply power to the relay. The test consists of: - starting up the VIP300 central unit self-testing sequence. - injecting a stimulus to simulate a phase fault. - injecting a stimulus to simulate an earth fault. - checking tripping. Frefer to the description of the test in the section entitled "test sequence" F the VAP6 is supplied by batteries. Therefore the parts of the VIP300 that run on AC current are not checked using this method (input and supply circuits). push-buttons n battery test: if the batteries are OK, the "on" indicator lights up while the button is pushed. n phase overcurrent: it sends the phase protection test stimulus. The stimulus is equivalent to 20 times the setting current. n earth fault: it sends the earth protection test stimulus. The stimulus is equivalent to 20 times the earth setting current Ios. n trip inhibition: press the "trip inhibition" button if the VIP300 test should be carried out without tripping of the circuit breaker. Circuit breaker tripping is inhibited while the trip inhibition" button is pressed, even if the tripping order results from a real fault. indicators n on: indicates that the batteries are operating. Also lights up when the battery test is carried out by pressing "battery test". n test in progress: confirms sending of the test stimulus to the VIP300. n trip: it is used to test other relays in the VIP range. It is not to be considered for the VIP300 test. (it lights up for a transient period when the VIP300 sends a tripping order; whether or not the circuit breaker is inhibited). "external mitop" output It may be used to connect an auxiliary mitop designed, for instance, to stop a stop watch during operating tests. The mitop is triggered at the same time as the circuit breaker mitop. It is not inhibited by pressing the "trip inhibition" button. batteries n the batteries are normally deactivated and are automatically activated when the VAP6 is connected to the VIP300. They are activated in the following cases: - pressing the "battery test" button. - direct connection to a VIP3X or VIP5X relay. - connection to the adapter cord designed for testing of the VIP1X or VIP2X relays. n to install or change the batteries, open the unit by removing the 4 screws on the bottom of the unit. Be sure to use the correct polarities. technical characteristics supply: 3 x 9V 6LR61 batteries weight: 0.45 kg dimensions: 93x157x45 20 technical manual VIP300

21 8. testing of the VIP300 and use of the VAP6 (cont d) VAP6 test sequence The test may be carried out with or without current in the sensors. During the test operations, all the VIP300 settings are effective; the relay should perform in accordance with the settings. During the test, the relay remains operational and will give a tripping order in the event of a fault, unless the "trip inhibition" button is pressed. n connect the VAP6 to the "VAP6 test plug". The VAP6 batteries are activated and the "on" indicator lights up. n press the VIP300 "reset" button. - if the 2 "trip" indicators were yellow, they become black. - the 2 red I> and Io> indicators of the VIP300 light up for about 3s to indicate that the central unit has correctly performed self-testing. n press the "trip inhibition" button if the test should be carried out without tripping of the circuit breaker. Fbe sure to continue pressing the "trip inhibition" button throughout the time it takes to send the stimulus. n press the "phase overcurrent" button to send the phase protection test stimulus. - continue pressing the button throughout the duration of the stimulus. The stimulus represents about 20 times the setting current. - the VAP6 "test in progress" indicator lights up to confirm the sending of the stimulus to the VIP300 relay. - the red "I>" indicator of the VIP300 blinks during the time delay period. - then the VIP300 phase "trip" indicator turns yellow. - the circuit breaker trips if it is not inhibited. F if the "phase overcurrent" button is held down after tripping, the VIP300 starts the time delay/tripping cycle again; this is normal operation. In that case: - the VAP6 red "trip" indicator lights up for a transient period each time there is a trip. - depending on the time delay setting, the VIP300 red "I>" indicator may be off or blink rapidly and/or in an irregular manner. n press "earth fault" to test operation of the earth protection. The stimulus injected is equal to 20 times the setting current Ios. Use the same procedure as for the phase protection test. n disconnect the VAP6. In order to save batteries, do not leave the VAP6 connected to the relay unnecessarily. technical manual VIP300 21
