Dynamic Ratings - Model BPM -Breaker Performance Monitor

Complete diagnosis of the breakers’ mechanical and electrical systems with every operation. Smart Capture uses a waveform analysis for graphical comparison of breaker operations, providing a detailed analysis of first trip open and close times, identification of latch and bearing performance, lubrication issues, auxiliary contact condition and fault current values.

Multi-parameter sensors monitor density, temperature and humidity in insulating gases. Then alarms alert asset owners of leakage rates, trending of time till lock out and mass gas loss.

Provides data concerning the condition of the stored energy system allowing the Breaker Performance Monitor to detect failures before the apparatus is called to operate.  Information such as this cannot be obtained from reactive logging devices such as microprocessor based protective relays.

While much attention is given to monitoring a circuit breaker’s timing and integrity of SF₆, a better understanding of how the breaker’s charging motor is performing can provide critical information as to the condition of the stored energy system. These stored energy systems can be susceptible to adverse effects in cold weather environments. The breaker performance offers several unique features designed specifically for cold weather events such as monitoring motor runtime and adapting in real time to changes with viscosity of hydraulic fluid due to temperature changes. The system can also monitor for excessive moisture and system pressure in pneumatics systems which are a symptom of freezing air lines. Regardless of stored energy system used in circuit breaker design, monitoring of charging motor will improve reliability of system in cold weather events.
