ZXFC Lightning Protection Tester: Verification Tool

Time:2026-06-11 Number:3

1. Introduction

Lightning and switching surges pose significant threats to power system equipment, making the performance of surge protection devices (SPDs) and arresters critical to grid reliability. Accurate testing of these components is essential to ensure they meet operational specifications. The ZXFC Lightning Protection Devices Tester is a specialized instrument designed to address this need, offering comprehensive DC parameter testing for various overvoltage protective components, including oxide zinc arresters (piezoresistors), ceramic 2/3-electrode surge arresters, and vacuum lightning arresters. Beyond its core testing function, the device also serves as a stable power source and constant current supply, enhancing its versatility in laboratory and field applications.

2. Key Functional Features

The ZXFC tester is engineered with user-centric and safety-focused features tailored for technical personnel:

Comprehensive Protection Mechanisms: Equipped with high-voltage (HV) short-circuit protection, over-current protection, HV preset, and range adjustment functions. The HV self-discharge time is less than 0.5 seconds, ensuring rapid discharge and minimizing safety risks.

Self-Calibration Capability: The built-in self-calibration function ensures measurement accuracy without relying on external calibration tools, reducing maintenance overhead.

High-Precision LCD Display: The clear LCD readout delivers real-time, high-accuracy data, supporting reliable analysis of test results.

Range Alarm Function: Users can preset measurement ranges; an audible alarm triggers if readings exceed the set range, preventing equipment damage from out-of-spec conditions.

Continuous Measurement Mode: Ideal for batch testing, this mode allows uninterrupted testing of multiple devices, improving efficiency in production or quality control scenarios.

Simplified Operation and Portability: The panel features intuitive controls for easy operation, while its lightweight design (1.5 kg) and compact dimensions (208mm × 190mm × 78mm) make it suitable for both laboratory and on-site use.
