Product Description

High Quality Vlf Withstand Tester High Voltage Electric Cable Tester

Description

VLF cable testing (very low frequency) is a technology used to test medium and high voltage (MV and HV) cables. The advantage of the VLF system is that it is small and lightweight, making it very useful in field testing. Compared with traditional DC withstand voltage testing for cable testing, DC testing cannot effectively test cross-linked polyethylene cables. DC testing also shortens the life of the cross-linked polyethylene insulation. Ultra-low frequency high voltage generators do not suffer from these shortcomings

Features

1. The high-voltage circuit can directly measure current and voltage, and can capture waveform data precisely and accurately.
2. The booster has a built-in high-voltage output protection resistor, and no external resistor is required.
3. Both high and low voltages use closed-loop negative feedback control circuits, and the output is not affected by capacitor boost.
4. The high-voltage control part uses a new type of light-controlled high-voltage switch component, which is high-precision, safe and reliable.
5. The color touch screen human-machine interface and modular software operating system are used, and the control is precise and intuitive.
6. When the output voltage exceeds the set value, the instrument automatically shuts down for protection. It has high and low voltage dual protection functions and can accurately start protection measures according to the set value on the high-voltage side, and automatically shut down for protection when the current on the low-voltage side exceeds the rated value.
