Secondary Current Injection Relay Test Equipment
Relay test equipment allows the engineer to inject a current into the relay and measure the resistance, voltage, current etc. A basic relay test looks at the resistance of the relay to check for shorts. The voltage and current transmitted and required by the relay can also be checked. The brands that offer this type of equipment are Chauvin Arnoux, GE, Megger, EuroSMC and T&R Test Equipment.
