INCON Optimizer 3
INCON Optimizer 3
The INCON® Optimizer3 Circuit Breaker Monitor delivers advanced automated reporting of all critical circuit breaker diagnostics to ensure uptime and facilitate predictive maintenance. The Optimizer3 is ideal for high-voltage, live or dead-tank, oil, vacuum or gas circuit breakers.
With early detection of circuit breaker deficiencies and automated system performance evaluation, the Optimizer3 Circuit Breaker Monitor provides utilities with the tools to help improve efficiency, extend equipment service life, and enhance reliability of their systems.

With 8 sensor inputs, 5 timing inputs, and an onboard ambient temperature sensor and supply voltage monitor, the Optimzer3 and its array of sensors deliver a complete diagnostics report of a circuit breaker’s performance. Utility technicians are empowered with the data to repair a small issue before it causes a substantial failure that may require equipment replacement or even an entire overhaul of a high-cost asset.

VOLTAGE & CURRENT MONITORING
Real-time voltage and current are measured with an array of high-accuracy, loop-powered voltage and current transducers. Applications include motor current, station battery voltage, heater current, and compressor run-time.

SF6 GAS MONITORING
SF6 gas density, pressure, and dew point sensors and fill point adapters aid in the mandatory compliance reporting required by the EPA, resources boards, and other regulatory agencies by monitoring for SF6 gas leaks and related indicators and automatically reporting any fugitive emissions.

SF6 GAS HUMIDITY ABSORBER
The SF6 gas humidity absorber is capable of passively absorbing up to 40 milliliters of water from SF6 gas, saving major expense compared to standard circuit breaker moisture removal. The corrosion-resistant absorber is easily connected to a circuit breaker's SF6 gas port.

TANK HEATER MONITORING
The Optimizer3 monitors the tank heater’s supply current using a universal power status monitor. If one or more of the heater elements fails, the Optimizer3 will assert a heater alarm.
