ZXVLF High Voltage Generator: Technical Overview and Applications

Time:2026-01-26 Number:2

Withstand voltage testing is a critical preventive measure for ensuring the reliability and safety of electrical equipment. The ZXVLF High Voltage Generator offers a sophisticated solution for both AC and DC withstand voltage tests, with a particular emphasis on Very Low Frequency (VLF) testing at 0.1Hz—a method strongly recommended by IEC for its effectiveness and efficiency.

This generator is especially suitable for testing equipment with large insulation equivalent capacitance, such as power cables, capacitors, and large generators and motors. By applying VLF voltage, it reduces the required power supply capacity while maintaining test severity, making field testing more practical and less cumbersome.

Key Features:

1.High Voltage Direct Sampling: Voltage and current data are sampled directly at the high voltage side, ensuring high accuracy and real waveform representation.

2.Over-Voltage Protection: The unit automatically shuts down within 20ms if the output exceeds user-defined limits.

3.Dual Over-Current Protection: Both high and low voltage sides are equipped with adjustable over-current protection for enhanced safety.

4.Built-in Protection Resistor: No external resistor is needed, simplifying setup and operation.

5.Closed-Loop Control: Utilizes high and low voltage negative feedback to eliminate capacitive rise effect during output.

Technical Specifications:

The ZXVLF series includes several models to accommodate different testing requirements:

1.ZXVLF-30/1.1: Peak voltage 30kV, supports capacitance up to 1.1µF at 0.1Hz. Weight: controller 4kg, booster 25kg.

2.ZXVLF-40/1.1: Peak voltage 40kV, similar capacitance range. Weight: controller 4kg, booster 35kg.

3.ZXVLF-50/5.0: Peak voltage 50kV, supports up to 5.0µF at 0.1Hz. Weight: controller 5kg, booster 55kg.

4.ZXVLF-80/1.1: Peak voltage 80kV, capacitance up to 1.1µF at 0.1Hz. Weight: controller 5kg, booster 45kg.

Each model varies in fuse rating and supports multiple frequencies (0.1Hz, 0.05Hz, 0.02Hz), allowing flexibility in testing different capacitive loads.

Conclusion:

The ZXVLF High Voltage Generator combines precision, safety, and versatility, making it an essential tool for technicians involved in maintenance and validation of high-capacitance electrical systems. Its compliance with IEC standards and user-focused design ensure reliable performance in demanding testing environments.
