ETI PI-6000 an Advanced Primary Injection Test Set

The principle of Primary Current Injection Testing is 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.

ETI PI-6000 Primary Circuit Breaker Test SetOne popular circuit breaker tester is the ETI PI-6000 Primary Circuit Breaker Test Set. The ETI PI-6000 is an advanced primary injection test set capable of testing circuit breakers up to 6000 amperes frame size. Incorporating 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, the PI-6000, offers an internal voltage sensor that automatically configures the AC control power section to be energized only when properly configured for the applied voltage.

ETI PI-6000 Primary Circuit Breaker Test Set advanced features:

Serial port: This standard serial port may be connected to a printer, computer, or other device to print or store time and current values of test results in ASCII format. It is set for 9600 baud, 8 bits, 1 stop bit, no parity.

Remote Terminal Jack: This RJ-12 modular jack provides a six wire connection to a remote serial terminal, which provides complete monitor and control functions as well as advanced features such as serial number entry and date/time functions.

Initiating Control: The advanced initiate circuitry provides both pulse preset modes for cycles or seconds for output duration. The pulse mode automatically pulses the output to any preset programmed duration.

Zero DC Offset: Use of digitally controlled SCR’s instead of a contactor to initiate the output of the test set eliminates closing time error and thereby ensures precise initiation at the zero crossover point of the output current waveform every time.
