Circuit Breaker Test System BT121

The complete toolbox for testing and analyzing high, medium and low voltage circuit breakers

 

Total function of circuit breaker test system (time test) is to collect and save the data quality related to circuit breaker (disconector switch, breaker) in offline state at which we can make decision about breakers performance quality based on this data. Also this system simulates all related maneuvers on breakers such as: Open, Close, Close-Open, Open-delay-Close, Close-delay-Open and Open-delay-Close-Open. And it extracts electro mechanical data of different parts such as: main and auxiliary contacts, open/ close coils and spring charge engine With these information we can be sure of breaker correct performance and we prepare essential prediction for the future.

- Special tests for contactors and non-operating mechanism breakers

- Graphical results for quick interpretation 

- PC control with BTSOFT software

- Extremely reliable and easy to use 

- Battery operated

  • - Measurement, analyzing and sampling of minimum and maximum course of contacts.
  • - Measurement, analyzing, sampling and calculating of rebounce, over travel and draw of damping lines. 
  • - Measurement, analyzing and sampling of spring course of contacts.
  • - Measurement, analyzing, and sampling of upper and lower safety limits of contacts.

 

Coils/ Motor Current and Voltage Test:

  • - Measurement, analyzing and sampling of voltage and current of open/ close coils (Ac, Dc).
  • - Measurement, analyzing and sampling of voltage and current of blocking relay (Ac, Dc). (optional)
  • - Measurement, analyzing and sampling of voltage and current and performance of anti-pumping relay       (Ac,Dc). (optional)
  • - Measurement, analyzing and sampling of current and voltage and performance of spring charge motor   (Ac,Dc).
  •  

 And other tests which are defined based on customer needs.
