DESCRIPTION

ETI PI-5000 is a versatile and technologically advanced primary injection test set capable of testing circuit breakers up to 4000 amperes frame size. It 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.

ETI PI-5000 is constructed in a rugged steel enclosure with removable sides and top for easy access to internal components. The sides are clear of protruding components, and full-width handles with provisions for lifting hooks are on both ends. Locking swivel castors on all four corners provide ease of mobility. The entire test set has been designed for reliability, ruggedness, and ease of use.

MAC-21 instrumentation controller provides advanced state of the art accuracy and convenience for testing The unique manual / motorized vernier design increases your test reliability and productivity. The vernier position is displayed on an LED indicator bar graph.

PI-4000B features temperature protection one for the output bus, and the other for the vernier Powerstat™. 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.

 

Applications

This test set will test low-voltage, molded-case and metal-clad, direct acting AC circuit breaker from various manufactures. The test set can also be used on high current applications like ratio transformers, and heat runs.

Using SCR’s the PI-4000B 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.

 

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. This interface enables you to download data into various computer software programs

Initiating Control: The advance 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. This provides additional testing capabilities for electromechanical and solid state trip devices. A short preset pulse duration also allows for instantaneous tripping without preheating the breaker under test. A long preset time can used for heat runs on cables or other devices up to maximum 9999 seconds.

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. Initiation at the zero crossover point ensures symmetrical output current by eliminating DC offset in the current waveform. Therefore accurate, repeatable test results are assured even with currents of very short duration, as when conducting tests of instantaneous or short delay trips
