Voltage regulator voltage and load test is shown as in the picture. Make the AC input ends1 &2 of the voltage regulator connected to standard voltage of 220V; make the secondary ends 3 & 4 connected to AC voltmeter V; spin the voltage regulator hand wheel and then the secondary output voltage should rise to 250V from 0V. In processing load test, ends 1 & 2 are connected to standard voltage of 220V, and secondary 3 & 4 are connected to the load. For example, a voltage regulator of 1KVA can be connected to electric stove of 1KW and concatenated with AC voltmeter A. Spin the voltage regulator hand wheel , and then the current reaches rated current value of 4A and keep the power on for 2 hours. If no abnormal phenomena such as smoking and smell of burning arise, the quality of voltage regulator TA is good.
