Product Description

Product Description

 

Advanced Cable AC Vlf Hipot Tester High Voltage Tester

Overview:

♦ Advanced Cable AC Vlf Hipot Tester High Voltage Tester is made for very low frequency withstand voltage testing of electrical devices.

♦ A substitute for the power frequency withstand voltage test is the very low frequency withstand voltage test. Compared to a power frequency withstand voltage tester, it is significantly smaller, lighter, and portable. The ability to replace power frequency withstand voltage testing with 0.1Hz ultra-low frequency testing has been demonstrated both domestically and internationally.

♦ It can be used for power cables, 10kV and 35kV power transformers, 300MW thermal power plants, and other electrical equipment.

 

Characteristic:

♦ Since waveform, current, and voltage data may be immediately sampled at high voltage sides, the data is accurate and real.

♦ Over-voltage protection: The instrument will switch off to protect itself if the output exceeds the set limit of voltage; fewer than 15ms pass before activation.
♦ Over-current protection: It has a high-low voltage dual protection design that allows for accurate shut-down protection to be made in accordance with the set value on the high voltage side; if the instrument's rated current is exceeded on the low voltage side, shut-down protection will be applied; both actuation times are less than 15 ms.
♦ The voltage boost body in the design includes a high voltage output protective resistor, which avoids the requirement for a separate protective resistor linked outside.
♦ The output is free of the capacitance rising effect as a result of the high and low voltage closed-loop negative feedback control circuit.
♦ The revolutionary light control HV switching unit used in the high-voltage control portion ensures precise, secure, and dependable control.
