Overview The transformer integrated test system complies with GB1094, GB / T4776, GB / T5169 and other relevant national standards. With the increase in transmission and electrical power generation and the continuous increase in power grids, the successful transformation of the national city network, the farnet, and the number of online quantities and capacity of power transformers are increasing. Technical parameter: Equipment measurement range and precision Voltage metering range: 50V 500V Voltage metering accuracy: 0.2% Current metering range: 0.1a 5a (can be 0.1A 1A) Current metering accuracy: 0.2%; Power frequency withstand voltage test Leak current: 400mA Input current monitoring instrument Monitoring range: 200A Function: Equipment failure automatic detection function, automatically detect peripherals, such as: the voltage regulator is zero, etc .; Test item: no-load loss measurement, no-load current percentage (automatic conversion to the value of the rated voltage), load loss measurement, the impedance voltage percentage (automatic conversion to the rated current reference temperature) Automatic measurement (voltage ratio measurement, connection group label test), external pressure test (power frequency withstand voltage test), induction pressure test (multiplier multiplier test), insulation resistance measurement, lightning shock test, insulation Oil test (breakdown voltage, flash point, acid value, volume resistivity, moisture, etc.), local discharge test, temperature rise test
