DTE-20M Primary current injector
DTE-20M primary current injector
AC high current primary curren tinjector DTE-20M purpose is functional check and taking ampere second characteristics of automatic circuit breakers working in AC in range of 20A-20kA. DTE-20M registers current values and tripping time of automatic circuit breakers. Also DTE-20M can be used as source of AC current, adjustable up to 20kA, in low impedance power networks.
Can be used both in single-phase and three-phase networks.
DTE-20M primary current injector is a mobile device, which could be easily transported to a required testing location.
