0 ₽
Product code:
  • High current tester HCT-3, hereinafter the ‘’device’’, is used for testing AC circuit breaker’s efficiency and ampere-second characteristics in 20A - 3kA range, with measuring and registration of time and current values, passing through circuit breaker.; for measuring and protecting transformers tests via primary current; for testing and calibration of current and heat-current relays; fuses testing. The device can be used as regulated current source (3 kA max) for lab operations. Output current-conducting circuits are galvanic coupled with power grid.
