High-Voltage Pulse GeneratorZC-700C

The ZC-700C High-Voltage Pulse Generator complies with the DL/T846-2016 and DL/T474-2017 standards. It is designed for impulse discharge testing to locate faults in cables rated at 35 kV and below, as well as for DC withstand voltage testing of electrical equipment.
This device integrates a DC high-voltage source, energy-storage capacitors, and a discharge ball gap, effectively replacing traditional, bulky testing equipment that typically weighs hundreds of kilograms. By utilizing high-frequency, high-voltage technology and specialized high-voltage components, the unit achieves a lightweight design, user-friendly operation, and exceptional safety and reliability; it remains fully functional even in the event of a high-voltage short circuit to ground. Consequently, it stands as an ideal, lightweight, and durable instrument for cable fault detection.

Features and Advantages

1. Features automatic protection functions against overcurrent, overvoltage, and overheating.

2. Capable of performing DC withstand voltage tests and impulse discharge operations.

3. Delivers a uniform and controllable high-voltage pulse output.

4. Features robust short-circuit protection, allowing the high-voltage output to operate safely even when directly short-circuited to ground.

5. Equipped with dual Class 1.5 analog meters for current and voltage display, offering an intuitive and clear interface that allows operators to instantly verify whether a fault point has been fully discharged, while providing real-time feedback on the discharge process.

6. High-voltage-side voltage measurement is performed in real-time with high precision.

7. Incorporates a “zero-start” protection feature to ensure enhanced safety and reliability.

8. Features a unique high-voltage measurement design wherein, even when the unit is in a stopped state, the voltmeter continues to display the real-time capacitor voltage value, ensuring the operator remains fully aware of the high-voltage status at all times.

9. The discharge duration can be freely configured within a suitable time interval.
