Activation is carried out by means of the Programming Unit. Unless detailed specification of the protection states otherwise, one of the following events may occur as a consequence of protection tripping: switching the bay off, i.e. disengagement of the circuit breaker (after switching off by the protection it is not possible to re-close the breaker before the magnetic flag is cancelled). The information about tripping of the protection is recorded into the event log (the last event). The principle of protection s operation is described in the following example: The setting values of the current overload protection I>: I = 1 I n, T = 1 s. Breaking of the circuit will take place if the set value of 1 I n is exceeded over the set period of 1 s OVERLOAD PROTECTIONS Note: In the MUPASZ COMPACT 3.W3 only one overload protection may be active: either the time constant or the reverse time one. If a second overload protection is to be activated the operator must confirm deactivation of the first one before ND stage independent overcurrent protection (I>) It is an overcurrent-type protection; its adjustable duration time does not depend on the electric current value Reverse time overcurrent protection (I> zal) It is an overcurrent-type protection with a time dependent (very inverse). current characteristics. Variation of electric current that flows through the protected line affects the tripping time of the protection. Therefore the time-delay interval depends on the value of the level of exceeding of the threshold limit. In case when the value of the electric current remains constant the time can be calculated by means of the following formula: where: I - electric current during tripping; T 10, I r - adjustable parameters; α=1, β=9 T = T I I r 10 α β 1 Aktualizacja

The protection is always active PROTECTIONS AGAINST EARTH FAULTS Note: The Ferranti transformer transformation ratio is assumed 120 and the secondary residual current I 0n (rated residual) is assumed 1 A. Both these parameters are constant and are not editable. Note: In the MUPASZ COMPACT 3.W3 it is possible to activate only one ground fault protection: either the overcurrent earth fault or the directional the overcurrent earth fault. If a second earth fault protection is to be activated the operator must confirm deactivation of the first one before Overcurrent earth fault protection (I 0 >) It is an independent overcurrent-type protection with time delay. It is tripped by neutral current I 0 from Ferranti transformer. mup_com_w01w023w3_en

16 12 MUPASZ COMPACT W01/W02/3.W3 User Manual Directional (angular) earth fault protection (I 0 > k) It is the zero-current protection (either for reactive or active current) with time delay. The start-up current is calculated by the formula: I = I m /cos(φ 0 +α) where: I m - electric current of maximum sensitivity (setting); φ 0 - phase angle between U 0 i I 0 ; α - setting for the angle. However, for reliable tripping of the protection it is required that the zero voltage U 0 would be not less than 15% U N. If the phase angle for the protection is set to zero, the protection can be tripped for the actual phase distance between voltages and currents within the 1 st and 4 th quadrant of the co-ordinates. It the preset angle is different than zero tripping is also possible for the 3 rd quadrant. The forthcoming diagram of current vs. phase characteristic curve for the angular protection against short-to-earth faults can be useful to facilitate the setting procedure. On the phase plane and for two preset values of the phase angle α = 0 and α = 90 o the diagram exhibits areas where the protection is applicable or not.
