■ functional features of high voltage circuit breaker analyzer

▲ time: inherent opening and closing time of 12 fractures, in-phase synchronization and phase to phase synchronization.

▲ reclosing: closing opening, opening closing, opening closing opening process time of each fracture: one opening time, one closing time, two closing time, golden short time and no current time value.

▲ bouncing: closing bouncing time, bouncing times, bouncing process and bouncing waveform of each fracture; Opening rebound amplitude of each fracture.

▲ speed: rigid opening and closing speed, speed, time stroke characteristic curve.

▲ stroke: total stroke, opening distance, overtravel, overshoot stroke, rebound amplitude.

▲ current: opening and closing current value and current waveform diagram of opening and closing coils.

▲ operating voltage: dc30 ~ 250V / 20A digital adjustable circuit breaker operating power supply is provided in the machine to automatically complete the low-voltage operating test of the circuit breaker and measure the operating voltage value of the circuit breaker.
