1300970224 Static Withstanding Voltage Tester is a high performance test measurement device widely used in Power, Electronics, Instrumentation, Military and Telecommunications Industries to test insulation resistance. It is mainly used to measure the insulation resistance of electrical conductors and insulators, which can be used to evaluate the strength of insulation ability of the device to be tested. The power supply for testing generally adopts AC 110V, 220V, or 380V. Its working principle is to provide a certain high frequency and high voltage pulse signal to apply to one end of the specimen (that is, the outer insulation, windings or between two points of the winding, body of the sample), while the other end of the sample is grounded.

The high frequency and high voltage pulse signal is generated by the charge pump circuit. The high voltage end uses the discharge button in the pulse high voltage, and the high frequency last stage is determined by the voltage impressed at the oscillating circuit end. The resistance value measured by this device is usually referred to as insulation resistance, which is related to the quality of insulation between conductors and is generally insulated and tested for a few seconds. The unit of insulation resistance is megohm. Its test principle is mainly capacitive coupling. When the test voltage is charged to a certain value, the energy stored in the capacitor is gradually increased until the current through the sample reaches its rated value. As a result, the dielectric strength and insulation of the specimen are tested through this process.

1300970224 Static Withstanding Voltage Tester can effectively measure power cords, photovoltaic cables, measuring cables, and other insulated cables. Through matching high and low voltage electrodes, it can bring different voltage levels into the test sample, such as AC 380V/1000V, DC 200V/1000V and so on. It is equipped with a high voltage lead to directly provide high voltage electric shock, which greatly improves the safety and accuracy of the test. Through manual selection of test mode, it can test the insulation properties of product quickly and accurately, which is beneficial for the detection of non-destructive, precise and fast insulation resistance. It can thereby detect insulation weakness and potential hazards caused by defective insulation in an electrical system.

In summary, 1300970224 Static Withstanding Voltage Tester is a versatile measuring tool widely used in power, electronics, instrumentation, military and telecommunications industries. It is mainly used to measure the insulation resistance of electrical conductors and insulators. It is able to bring different voltage levels into the test sample and detect insulation weakness. Its application field involves testing the insulation properties of various wires and cables, which can be used to evaluate the strength of insulation ability of the device to be tested.
