Secondary Injection Test Sets

AC-PRO^® and AC-PRO-II Test Set^®

AC-PRO on a GE AK-25 Breaker The Model B-292 Secondary Injection Test Set is a single-phase test set specifically designed for testing the operation of the AC-PRO® and AC-PRO-II® micro-controller based trip units manufactured by Utility Relay Co. The test set can test pick-up and time delays of the various protection functions by driving current into the trip unit on the secondary side of the CT circuit. The test set will test 60, 50, 40 or 25 Hertz AC-PRO® trip units. (The AC-PRO-II® can be set for either 50 Hertz or 60 Hertz). The test set will test the AC-PRO® or AC-PRO-II® trip system with the exception of the CTs and associated wiring harness.

ZERO-Hertz Test Set^®

AC-PRO on a GE AK-25 Breaker The Model B-290 test set is specifically designed for secondary injection testing of the ZERO-Hertz DC trip unit. Pick-up and multiple points on the time-current curves can be quickly tested using this test set. The test set can perform pick-up and time delay trip tests for either the transducer inputs or the shunt inputs depending on the model ZERO-Hertz DC trip unit. The ZERO-Hertz DC trip unit is micro-controller based and includes a 16-character liquid crystal display (LCD). The trip unit provides the following protection functions:
