The AC voltage withstand tester has the characteristics of high accuracy, good linearity, and anti-interference ability, which can replace traditional ordinary clamp meters and large-diameter clamp meters to measure high current leakage current. It is widely used in fields such as power, communication, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, and industrial and mining enterprises. It is particularly suitable for current testing in industrial environments with severe signal distortion, such as places with dense wiring, transformer wall connected subway core current testing, thick wire cable testing, relay protection, thyristor rectification, variable frequency speed regulation, semiconductor switches, power electronic conversion equipment, arc welding, etc.
The functions and characteristics of the communication voltage tester:
The AC withstand voltage test is conducted when the voltage, waveform, frequency, and electric field state inside the tested insulation are consistent with the electrical parameters of the actual operating state of the electrical equipment. Therefore, it can effectively eliminate defects in the main insulation of the electrical equipment, and the AC withstand voltage test is relatively effective. DC withstand voltage testing is more effective and can better reflect the insulation of electrical equipment.
The AC voltage tester is different from the series resonance tester. Although it can output voltage and current at a frequency of 50Hz, the usage environment is different. The series resonance testing device is suitable for power cables and transformers due to its large capacity and high voltage, GIS。 Such as large capacity electrical appliances and portable AC withstand voltage testers, used for small capacity AC withstand voltage testing of switchgear, medical equipment, electronic components, instruments and meters.
The portable AC voltage withstand test has excellent performance and can set leakage current values. When the test exceeds the leakage current setting alarm value, it can automatically prompt and display in full digital format. The output voltage can be manually adjusted to 0-5KV. The large measurement leakage current is 20mA, and the output waveform is a 50Hz sine wave. It has functions such as time preset and display, measurement countdown, etc. It is easy to operate, safe and reliable. The portable AC withstand voltage test complies with the relevant provisions of GB4706.1 "General Requirements for Safety of Household and Similar Electrical Appliances" and GB9706.1 "General Requirements for Safety of Medical Electrical Appliances" and GB4943, GB4793 standards, and requires the necessary testing equipment.
