PULSAR takes relay testing to the ultimate level with actual reproduction of faults, including dc offset and harmonics. Transient waveforms can be produced by PULSAR in several ways: mathematically using Fourier
PULSAR is designed to test virtually any relay, from simple overcurrent relays to complex three-phase, microprocessor-based relays requiring phase-shifting capability. This table lists relays by IEEE device number and matches them with the required combination of current and voltage amplifier modules. Base unit includes Input Power and Control ...
Test Equipment PULSAR Operating Manual Instructional Material. Description of Relay. The CVE is a synchro-verifier relay and the CVE-1 is a synchro-verifier relay with line and bus voltage sensing relays. The synchro-verifier is used to verify the condition of synchronism existing between two system voltages.
The PULSAR® Universal Protective Relay Test System represents the next generation in protective relay testing. This one-unit, modular system lets you select the testing capabilities you need now and expand as your requirements change. The PULSAR base unit includes the chassis, back plane, and input power and control module.
A typical example is AVO’s relay test set EPOCH-10. Launched in the 1990s it was a microprocessor based device (Figure 1 and table 1). The device could be used for testing of single phase overcurrent, directional, distance and frequency relays.
depressing the RESET button on the timer before the test set can be INITIATED. Therefore, should the test set fail to INITIATE upon depressing the INITIATE button, reset the timer and then re-initiate. If the timer still fails to INITIATE, check the NORMAL/DROPOUT Switch which is located in the auxiliary section
Add up to three current and three voltage amplifier modules to create a full, three-phase relay test system in one portable unit. Configured to provide complete three-phase variable current, voltage, frequency, phase angle, dc voltage, dc current, control, timing and monitoring functions.
