WebIn secondary current injection testing, you inject a three-phase current into the trip unit. This allows you to verify the trip unit polarities at the same time. However, one major drawback of this testing is that you can inspect only the trip unit logic and the system’s wiring. Unlike primary tests, you cannot check all the current-carrying ... WebThe 4031 is a hand held frequency selective ammeter and voltmeter used to measure the I/V magnitudes and. phase of signals induced into an earth loop via a. high power current injection system such as the. Model 4041 and 4046. The voltmeter part of the 4031 allows, fall of potential and step & touch voltages.
