DTE-series primary current injectors are capable of testing the time-delay characteristics of molded circuit breakers when recommended test procedure of testing the time delay. Also it can be used as a source of high current in continuous mode.
Higher currents are available for the short durations required to test an instantaneous trip element.
·Circuit breakers testing / Molded automatic circuit breakers test
·Light, portable primary injection test instruments
Available standard models of primary current injectors:
DTE-series relays and circuit breakers testing devices act as secondary current injectors are intended for:
- Testing and adjusting of simple relay protection, which already installed on power plants, substations, industrial-governmental enterprises or laboratories.
- Testing and adjusting automation elements (electromagnetic relays, contactors, motor starters, etc.).
- Testing, commissioning and adjusting circuit breakers.
