The Heater Monitor module is designed to actively test circuit breaker
heaters and associated power supplies to ensure proper operation. It is mounted in the
auxiliary module enclosure. The Heater Monitor module tests heaters by turning them on for
5 seconds at intervals set by the user. It may also be used for controlling the heaters,
turning them on if the temperature drops below a point defined by the user.
The Motor Monitor module is designed to provide ongoing data regarding the
health of spring charging motors, air compressors or hydraulic pumps associated with the
breaker. The Motor Monitor module provides an operational check on the energy accumulation
and detailed information about motor behavior. The user can detect deterioration in the
health of the system over time if the motor's runtime per breaker operation changes
dramatically.
The Operation Current Monitor module is designed to measure current
interruption and the operating time required for the breaker to calculate I2T
information. This module employs the OPTimizerä by INCONÒ to provide real-time operation and wear information.
The Pneumatic/Hydraulic Pressure Monitor (PHPM) module is designed to
continuously monitor the air and hydraulic pressure required to trip or close the
operating mechanism of the circuit breaker. It measures a drop in pressure and the
recharge time for the compressor or pump for each operation and provides trending
information on performance.
The Trip/Close Coil Module monitors the readiness of circuit breaker trip
and close coils by continuously monitoring the coils electrical flow. The module has
the ability to monitor as many as four coil circuits simultaneously.
