Circuit Breaker Analyzer
The ZWKC-G2 is a comprehensive mechanical characteristic tester designed for high-voltage circuit breakers.
It tests 12 metal contacts simultaneously, integrating a DC20~270V power supply for efficient field testing of vacuum, SF6, and oil switches.
Product Overview
The ZWKC-G2 High Voltage Circuit Breaker Analyzer is precision-engineered to evaluate the mechanical dynamic characteristics of high-voltage circuit breakers, including vacuum, SF6, and oil types.
By offering comprehensive measurements of opening/closing time, speed, bounce, and synchronization, it provides essential diagnostic data to ensure the reliable operation and safety of electrical power systems.
Key function and feature:
- Suitable for domestic and foreign SF6 switches, GIS, vacuum switches, and oil switches, delivering versatile diagnostic capabilities for substations and electrical test sites.
- Features a built-in DC20~270V adjustable power supply supporting up to 20A, eliminating the need for an on-site secondary power source and supporting internal trigger operation safely.
- Capable of measuring 12 metal contact fractures, 6 main fractures, and 6 auxiliary fractures concurrently, providing comprehensive time, speed, and bounce data in a single operation.
- Equipped with both linear and 345° rotary sensors with universal brackets for simple, rotation-blind-spot-free mounting on various breaker types and moving contacts.
- Utilizes a 7-inch color screen clearly visible under sunlight, coupled with built-in storage for 100 sets of test data, USB data transmission, and a high-speed thermal printer for immediate on-site reporting.

The instrument is designed to test a wide range of high-voltage circuit breakers, including domestic and foreign SF6 switches, GIS combination electrical appliances, vacuum switches, and oil switches.
No, the ZWKC-G2 features an integrated machine operation power supply providing an adjustable DC20 to 270V output. This allows you to perform closing and opening tests without a site secondary power source.
Yes, it accurately measures the opening and closing times of 12 natural switching contacts simultaneously, calculating the time difference between different periods and three-phase synchronism.
For vacuum switches, the included linear sensor is typically attached to the vertical conductive rod (moving contact) using a magnet and secured with a universal bracket. Ensure the electronic ruler is perpendicular to the moving contact before testing.
