Equipped with a visual interface for easy information retrieval and recognition, it is suitable for various types of medium and high-voltage circuit breakers. Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages. Circuit Breaker Test Equipment is used for testing, analyzing and assessing power system circuit breakers, mechanical characteristics of load switches and isolated switches and other AC high voltage switches, contact resistance, Arcing contacts and vibration characteristics etc. The functions of Circuit Breaker Test Equipment cover all testing items of high voltage circuit breaks. Comparing with the traditional circuit breaker tester, this Circuit Breaker Test Equipment has the following unique advantages: 

n  The integrated vibration test function of Circuit Breaker Test Equipment provides a new means of detection circuit breaker mechanical characteristics for users, compared to traditional time measurement and speed measurement, the vibration fingerprint detection is easier and more efficient. 

n  The vibration fingerprint test results contain richer information of circuit breaker operation, for potential risk of failure or faulty breakers, it can locate the fault position quickly. 

n  The vibration tests do not need to change the original line connection, so the users can complete the charged detection of mechanical characteristics of circuit breaker. 

n  Arcing contact analysis module allows users to automatically assess the degree of loss of inside Arc suppression contact of circuit breaker without disassembly. 

n  Users can use Circuit Breaker Test Equipment to complete the contact resistance tests, do not need to buy contact resistance tester separately. 

Circuit Breaker Test Equipment is used for testing and analyzing high voltage circuit breakers, load switches and isolated switches and other AC high voltage switches, and the main functions are as following: 

n  Measurement of closing time, opening time, time spread between poles, time spread between units of one pole, bounces etc. 

n  Measurement of closing speed, opening speed and average speed.
