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.
This configuration tests single-phase relays. Add up to three current and three voltage amplifier modules to create a full, three-phase relay test system in one portable unit. Complete three-phase test system in one unit. Modular design for system customization. Steady-state and dynamic testing.

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.
5 ημέρες πριν · Step 2 – Testing Coil Resistance. Set the multimeter to the resistance or ohms setting. Connect the multimeter probes to the coil terminals. Expected resistance values vary by relay but typically fall between 50 and 120 ohms. If the reading is significantly higher or lower than specified, it may indicate a faulty or damaged coil.
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
SVERKER 750/780: Relay test sets for secondary testing of protective relays. Test single-phase, three-phase protection, phase shifting, and automatic reclosing.
