Product Overview:
5KVA/360V 150Hz Induced Withstand Voltage Test Device Price, the induced withstand voltage test for transformers, mutual inductors and other equipment is a mandatory item for product delivery and testing. It is an important test to ensure the quality of transformers, mutual inductors and other products.
The induced withstand voltage test requires a set of power supply devices that are compatible with it. Generally, the frequency should be selected between 150-250HZ. Since it is not a 50HZ power frequency power supply, domestic commonly used variable frequency generator sets or three single-phase transformers connected in an open delta are used as the power supply for the induced withstand voltage test. The frequency of the variable frequency generator set is often selected between 100-400HZ, and when three single-phase transformers are connected in delta, a 150HZ voltage can be obtained.
The variable frequency generator set is bulky, not easy to transport, not suitable for on-site use, and when the capacity is not large, the waveform is also not good. Three single-phase transformers connected in an open delta can obtain a 150HZ power supply, but the waveform and capacity will change with the load, and it is very easy to resonate with the test object, causing resonance overvoltage and damaging the test object.The triple frequency power supply device has the characteristics of large capacity, good waveform, low distortion, light weight, and easy on-site use. From the triple frequency power supply to the complete set of test devices and operation methods, in-depth exploration has been carried out, and this series of triple frequency tuning power supply devices has been ideally developed.

Terminal Description:
The triple frequency power supply device produced by our company uses a voltage regulator output for 3-10KVA, and an inductor-capacitor output for 10KVA-1000KVA:
Usage Method:
(1) With voltage regulator (3KVA-10KVA)
(1) Connect according to the wiring diagram, then adjust the overcurrent protection current value according to the test object.
(2) Set the voltage regulator to the lowest position, close the power switch, the zero position indicator light is on, check for phase loss, and start the test bench.
(3) Adjust the voltage regulator so that the triple frequency output voltage reaches the test voltage, use an oscilloscope to measure the output voltage waveform, frequency, and output voltage value, so that it meets the test requirements of the test object.
(4) After the test, adjust the voltage regulator so that the triple frequency output voltage is zero, the zero position indicator light is on, and then open the switch.
(5) Cut off the power supply, and the test is completed.
(2) Without voltage regulator (10KVA-1000KVA)
(1) Connect according to the wiring diagram, then adjust the overcurrent protection current value according to the test object.
(2) Set the inductor to the highest position, turn on the power switch, check for phase loss, and start the test bench.
(3) Adjust the inductor handle to boost the voltage meter. When the current is at the lowest current, resonance occurs, reaching the test voltage value. Measure the output voltage waveform, frequency, and output voltage value until the test power supply requirements of the test object are met.
(4) After the test, adjust the inductor handle to reach the high position.
(5) Cut off the power switch, and the test is completed.
