Purpose
High current tester HCT-20 (hereinafter the “device’’) is used for testing AC circuit breaker’s efficiency and ampere-second characteristics in 20A - 20kA range, with measuring and registration of time and current values, passing through the 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 (20 kA max) for lab operations. Output current-conducting circuits are galvanic coupled with power grid.
