Ramp and high voltage current transformers are similar. It is essentially a two-winding step-down transformer. In theory, the power of the primary and secondary sides is equal, and the voltage of the primary and secondary sides is inversely proportional to the current during operation. Then the result is to reduce the voltage while rising High load current. After the riser is connected to the operating power supply, the output voltage of the regulator is adjusted to obtain the large current required for the test. The working principle diagram is as follows: TA—stop button QA—high current generator start button K—zero switch A— ammeter KM—AC contactor KT—transformer T—regulator HDLD—signal light BCDF—riser V—voltmeter Mannheim Process Potassium Sulphate Production Line Hebei aoliande Chemical Equipment Co., Ltd , https://www.aoliandepipes.com
