Digital VLF Hipot Tester 80kV Very Low Frequency AC Voltage Test Equipment with 7 Inch Touch Screen for Power Cable Testing

Product Introduction

The SXCDP-80kV Very Low Frequency AC Hipot Tester is developed for high-voltage withstand testing of electrical equipment, particularly test objects with relatively large insulation capacitance.

By using very low frequency AC testing technology, the system provides a practical solution for on-site insulation testing of power cables, capacitors, generators, motors, and other electrical equipment.

Main Product Advantages

1. 80kV High-Voltage Output

The SXCDP-80kV provides an output voltage of up to 80kV, making it suitable for a wide range of high-voltage insulation withstand testing applications.

2. Flexible VLF Frequency Selection

Four test frequencies are available:

• 0.1Hz | 0.05Hz | 0.02Hz | 0.01Hz

The available load capacity increases as the selected frequency decreases, with a maximum specified load of 5.5μF at 0.01Hz.

3. Intelligent Test Management

The system uses digital frequency conversion and microcomputer control to manage important test operations, including voltage increase, voltage reduction, measurement and protection.

This reduces the amount of manual intervention required during testing.

4. Touchscreen Human-Machine Interface

A 7-inch LCD touchscreen provides a clear operating interface for test parameter setting and monitoring.

The instrument also supports Chinese and English language switching.

5. Fast Multi-Level Protection

The tester incorporates overvoltage protection together with overcurrent protection on both the high- and low-voltage sides.

The specified protection response time is ≤10ms, providing rapid protection during abnormal operating conditions.

6. Stable Output Control

A high- and low-voltage closed-loop negative-feedback control circuit is incorporated into the system to maintain controlled output characteristics during testing.

Typical Applications

• Power Cable Testing

  Suitable for VLF AC withstand testing of power cables, particularly cable systems with relatively large insulation capacitance.

• Generator Testing

  The system can be used for withstand testing of large and medium-sized generators.

• Motor Testing

  Applicable to high-voltage insulation testing of large and medium-sized motors.

• Capacitor Testing

  The VLF system is also suitable for testing power capacitors and other capacitive electrical equipment.
