OPTIMIZER3 OVERVIEW
This guide is written for the Optimizer3 with firmware version 1.9.1 and higher.
The Optimizer3 is an on-line continuous performance monitor for high voltage circuit breakers. It provides information for the
process of Condition-Based Maintenance
Optimizer3 performs four main functions:
1. Mechanism Timing.
2. Estimation of interrupter condition as degraded by internal arcing effects.
3. Measurement of SF₆ gas density, pressure, and dew point temperature.
4. Status Monitoring of Auxiliary systems.
The Optimizer3 is designed to be installed in the circuit breaker control cabinet. Usually this is the most convenient place because
there is easy access to SF₆ plumbing for the density sensors, bushing CT circuits, and control circuits. Often the O&M technicians
have no access to the control building where the protective relays are located. If it is not possible to locate the Optimizer3 in the
control cabinet, then it may be installed in the control building. Most often this decision is based on access to communication links
or SCADA RTU access.
For use as a SF₆-only monitor, such as for monitoring compartments of GIS or SF₆ insulated bus, the Optimizer3 may be located up
to 2000 feet from the digital SF₆ density or pressure sensors if AWG 14 wire is used. This makes it feasible to locate the Optimizer3
in a control building, near communications access points.
If access to circuit breaker control cabinets is restricted, Optimizer3 may also be installed in a separate enclosure, mounted to the
frame of the circuit breaker. This way, Optimizer3 can be accessed without opening the circuit breaker control cabinet, without
restriction of the breaker being taken out of service.
