Merlin Gerin Secondary Injection Test Set

POSTED BY Protec Tech Team

Many circuit breakers are tested by use of secondary injection test equipment applied to the breaker’s trip unit. These specialty test sets check the trip function of the circuit breaker — in other words, whether the electronics in the breaker are functioning properly. When you have work requirements that involve testing and maintaining Merlin Gerin circuit breakers, the Merlin Gerin Secondary Injection Test Set is ideal for verifying the proper operation of the trip circuitry. Merlin Gerin is only one of several well-known brands in the Protec stable of test equipment rental.

For Accurate Ductor Testing - Raytech Micro Centurion II Micro-Ohm Meter

POSTED BY Protec Tech Team

A contact resistance test (also known as a ductor test) measures the resistance of electrical connections such as joints, terminations and connectors. These can be connections between any two conductors, for instance busbar sections or cable connections. The test measures the resistance at the micro- or milli-ohm level and is used primarily to verify that electrical connections are made properly, and can detect the following problems:
