1. Overview

A system that monitors the voltage on the Circuit breaker's operating coil, the current on the coil when operated, the change in the protective contacts, and the secondary current on the BCT, to monitor the Circuit breaker's operating state and operating characteristics.

It monitors the status and behavioral characteristics of the Circuit breaker in real time, bringing efficiency to the management of the Circuit breaker.

2. System feature

-Prevention of economic loss in the event of an accident by diagnosing abnormalities in facilities;

-Systematic maintenance management of breakers by CBM method (Condition Based Maintenance)

-Easily recover from failures quickly with accumulated data KEPCO, KORAIL, large factories, industrial facilities, etc.

• Monitoring of mechanical contact mechanisms of circuit breakers and deterioration monitoring of contacts
• Monitor cumulative number of operations online from a remote location using the Auxiliary contact point of the breaker.
• Automatic calculation of cut-off current at each angle of the breaker
• Measure the cut-off current of the breaker and monitor the amount of wear at the contact point of the breaker.
• Enter the output signal 0 ~ 5A or 0 ~ 1A from the Auxiliary CT
• Enter a minor contact point for each phase
  - CB operating current: 3 per CB (when applying 3 phases)
  - Number of CB operations: 3 per CB (when applying 3 phases)
