Product Introduction
This Circuit Breaker Test Set is a specialized equipment used in power systems to test the mechanical action characteristics of high-voltage switchgear such as circuit breakers, isolating switches, and grounding switches. Its most core and distinctive technology is the "dual terminal grounding" testing function, which solves a major problem encountered by traditional testing methods in the field.

Core advantages of Circuit Breaker Test Set
1. Extremely high safety: completely avoiding the operational risks and electric shock risks (induced electricity, misoperation, etc.) caused by disconnecting the grounding knife switch. During the testing process, both sides of the circuit breaker are always in a safe grounding state, in compliance with the strictest safety regulations.
2. Wide applicability: It completely solves the problem of testing GIS equipment, compact substations, old substations, or specific safety requirements where grounding cannot be disconnected. Suitable for all types of high-voltage switchgear (AIS, GIS, HGIS, tank circuit breakers, column circuit breakers).
3. Easy and efficient operation: eliminates the tedious steps and waiting time of disconnecting and restoring the grounding knife switch, greatly shortens the preparation time for testing, and improves on-site work efficiency.
4. High reliability of testing: Advanced isolation and differential measurement techniques are adopted, with strong anti-interference ability, ensuring the accuracy of test data even in complex on-site electromagnetic environments.
Typical application scenarios of Circuit Breaker Tester
Regular preventive testing or post maintenance testing of circuit breakers in substation GIS equipment.
An open type (AIS) substation with limited space and inability to disconnect one side of the grounding.
The safety regulations strictly require that the equipment must be grounded on both sides during testing.
Need to quickly complete a large number of switch tests and pursue high efficiency in situations.
In situations where there are security concerns regarding traditional testing methods.
