ETI PI-6000, A Primary Circuit Breaker Test Set You Can Depend On

eti_pi-6000The principle of primary current injection testing  is very straightforward: a test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. By injecting a predetermined current into the circuit breaker, it is possible to determine whether the relay will trip at this current and, if so, how long the current needs to flow before the trip is initiated.

The ETI PI-6000 Primary Circuit Breaker Test Set is a technologically advanced primary injection test set capable of testing circuit breakers up to 6000 amperes frame size.

The test set incorporates an output transformer with dual primaries to facilitate its use on power sources of 480 VAC as well as 240 and 208 VAC, and dual secondaries to provide optimal impedance matching to a wide range of breaker sizes. An internal voltage sensor automatically configures the AC control power section to be energized only when properly configured for the applied voltage.

The ETI PI-6000 features dual temperature protection, one for the output bus, and the other for the vernier Powersatat™. If either temperature exceeds a safe operating level, the interlock is asserted and the output section is de-energized. Primary catastrophic overload protection for the test set is accomplished with input fuses having high interrupting current capacity.

Using SCR’s the ETI PI-6000 eliminates closing time errors. Initiation at the zero crossover point eliminates DC offset in the current waveform and results in accurate, repeatable test results even with short-duration currents for high speed solid state or electromechanical trip devices.
