General information about ADPI-A Primary Current Injection Test Set
ADPI-A series Automatic Primary Current Injection Test Set is mainly used for primary bus protection and whole group driving test of current transformer. It is also used to calibrate air switch, switchgear, circuit breaker and protection screen.
Features:
Full keyboard operation,intelligent working process.
Real-time display output current,time and result
Routine current rising test
Impulse quick break test
Transformer turn ratio polarity test
Automatic timing after required output current is arrived. After timing is over, it returns zero automatically.
If the current is over upper limit, it returns to zero automatically and alarm.
Current can be set randomly, accuracy 1.0% .
Output current is standard sine wave, wave distortion <5%
Timing range:0-9999ms, resolution 1ms
Time Error:0.005%, range:+-2digits.
Displaying primary and secondary current, convenient for turn ratio calibration test of CT/PT.
Optional function:
Current action time of test object
Synchronously record and lock action time
Temperature rising is customized according to long time working temperature rising.
