The equipment can output a variable current up to 250A, a variable AC Voltage up to 250V, a variable DC Voltage up to 350V. Also the unit incorporates a variable stabilized auxiliary DC Voltage supply up to 250V and a fixed AC Voltage output up to 110V, which can be variable with the PTE-FCF option. The equipment is extremely compact, and contains all the functions necessary for current and voltage relays. It incorporates various measurement functions such as a voltmeter, ammeter, frequency meter, as well as measures apparent power, impedance, and internal and external phase angles. From the front panel controls, the maximum output injection can be limited, used for example in testing instantaneous overcurrent relays. Injection time can also be limited, useful to safely test reclosing devices. FEATURES The PTE-100-C is designed in a way that enables testing of protective relays in an effective and easy manner for the operator. There is a variable dc voltage output for the auxiliary voltage supply for electronic relays, which is independent of the main current and voltage outputs. For the testing of overcurrent and maximum or minimum voltage relays, the unit has 2 Displays that indicated the output value and trip time respectively. In the case of testing timing characteristics (inverse, very inverse, etc) the current value being injected can be presented in percentage of the The PTE-100-C can communicate with a PC via the serial port RS-232, and can be connected to other PTE units via the BUS-PTE.

3 PTE-100-C and PTE-300-V One high current and three voltage outputs. nominal relay current, in a way you can compare the results with the theoretical characteristics. When testing instantaneous devices the unit can be set in the maximum current measurement mode (Imax), limiting the maximum current to be injected (Ilim), and limiting the time of injection (Tlim). The pre-selection mode (Preset) enables the current value to be pre-selected, when the impedance of the load is previously measured, thus avoiding the preheating of relays. Impedance measurement (Ω): - Measures the impedance connected to the current circuit. - 4 wire measurement method. Apparent Power Measurement (VA): - The power consumed in the current circuit. - Power V x I. MEASUREMENT FUNCTIONS The PTE-100-C contains the following measurement functions: Ammeter: External current measurement up to 10A can be measured. Voltmeter: External voltage measurement up to 400V in ac and dc, and with the option PTE-FCH up to 1,000V. Frequency meter: External frequency measurement from 20 to 2000 Hz. Phase angle meter enables to measurement of the phase angle between: - The current produced by the PTE-100-C and the voltage in the output taps, the impedance angle of the load. - The current produced by the PTE-100-C and an external voltage. - External current and voltage. ϕ V I INTERCONNECTION CAPABILITY The PTE-100-C can be interconnected, with a simple BUS-PTE cable, to any other equipment in the PTE Range (PTE-100-V, PTE-300-V, etc). When connected to the PTE-100-V, the combination is a complete single-phase relay test system that can test overcurrent directional relays, differential relays, or synchronizing relays. When connected to the PTE-300-V, the combination forms a system of 3 voltage outputs and 1 current, that can test relays which require 3 voltages to function correctly, such as distance relays, and directional power relays, etc.
