What are the applicable ranges of ultra-low frequency cable voltage tester

The application range of ultra-low frequency cable withstand voltage tester is quite wide, mainly including the following aspects:

1. Cable testing

① High voltage power cables: The tester can be used to test the insulation strength of various high-voltage power cables, ensuring that they can withstand the voltage requirements under normal operating conditions.

② Cable accessories: including cable connectors, cable terminals, etc. The insulation performance of these accessories is equally important, and the ultra-low frequency withstand voltage tester can effectively test them.

③ Cross linked polyethylene insulated power cable: It is particularly suitable for testing the voltage resistance performance of cross-linked polyethylene insulated power cables, as this type of cable is widely used in power systems and has high requirements for insulation performance.

2. Power equipment testing

① Large high-voltage rotating electrical machines, such as generators, motors, etc., typically have insulation layers with large capacitance, and can be tested more safely and economically using ultra-low frequency withstand voltage testers.

② Transformer winding: Transformer is one of the important equipment in the power system, and the insulation performance of its winding is crucial for the safe operation of the transformer. The ultra-low frequency withstand voltage tester can be used to test the insulation strength of transformer windings.

3. Other electrical equipment testing

① Power capacitors: used to test the insulation performance and dielectric loss parameters of power capacitors.

② Insulation materials: can be used to test the voltage resistance performance of various insulation materials, such as rubber, plastic, etc.

③ Instruments and office equipment: Conduct insulation strength tests at specified voltages to assess the insulation level of products.

4. Special application scenarios

① Partial discharge measurement: During partial discharge measurement, an ultra-low frequency withstand voltage tester can be used to apply terminal voltage and continuously observe the discharge amount to evaluate the insulation performance of the equipment.

② Preventive testing: Regular preventive testing is necessary to ensure the safe operation of electrical equipment. The ultra-low frequency withstand voltage tester can be used as a means of preventive testing to detect insulation weaknesses or faults in equipment.

In summary, the application scope of the ultra-low frequency cable withstand voltage tester covers multiple fields such as cables, power equipment, and other electrical equipment. By using this tester, the insulation performance of equipment can be effectively evaluated, ensuring the safe and stable operation of the power system.

The ZC-524C ultra-low frequency high voltage generator adopts a 7-inch touch screen, imported high-speed AD acquisition circuit, and advanced production technology, which improves the quality stability of the instrument and reduces the volume and weight of the equipment. The device is easy to operate and overcomes the disadvantages of short service life, high failure rate, and large volume of mechanical boosters of similar domestic products. Compared to other types of withstand voltage testing equipment, 0.1Hz ultra-low frequency has many advantages, such as good equivalence, low insulation damage, high operational safety, simple test wiring, and small equipment size.
