Operation Current

Function

The module employs three split-core measuring devices to monitor the output of existing relay or metering CTs. The circuit breaker's operating time information is gathered from its auxiliary switches and compared with set alarm levels.

The base unit uses a dedicated RS-232 port and a standard nine-pin serial computer cable to interface with the OPTImizerä.

Features

	Provides cumulative I^²T information per phase
	Excessive arc time detection
	Measurement of mechanism timing
	Provides I^²T endured by main contacts for every operation.

Benefits

	Re-strike detection (per IEEE definition)
	Quantitative information for scheduling maintenance.

Data

All information is recorded by and stored in the OPTImizerä unit. The SMSmart program in the SM6-1/3 unit provides easy access to and download of this information.

Alarms

All module and base unit alarm parameters may be set by the user. Alarms may be enabled or disabled at user discretion.

This product incorporates technology developed for the Electric Power Industry under the sponsorship of EPRI, the Electric Power Research Institute
