EXTEND THE LIFE OF YOUR CIRCUIT BREAKER- With early circuit breaker problem detection and automated system performance evaluation, the Optimizer3 provides utilities with the tools to help improve efficiency, extend equipment service life, and enhance reliability of their systems.

24/7 REAL-TIME ANALYSIS- The web-based software provides monitoring data on both the mechanical and electrical performance of a circuit breaker, delivering trending analysis that predicts the date of future service.

CONDITION BASED MAINTENANCE- Armed with a high degree of circuit breaker performance insight from the Optimizer3, utilities can deploy maintenance with intelligence and only as needed – limiting truck roles, speeding reaction time, and lowering overall maintenance costs.

BREAKER TIMING- In the milliseconds it takes for a circuit breaker to trip, the Optimizer3 collects a full battery of timing data including opening (trip) time, clearing time, arc duration, and opening/closing travel times and velocities are automatically analyzed to provide a full assessment of the circuit breaker’s health.

SF6 REPORTING-The Optimizer3 aids 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.

COMPLETE CIRCUIT BREAKER DIAGNOSTICS- 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.

REMOTE WEB INTERFACE-The web-based interface allows users to securely connect directly to the Optimizer3 monitoring and alarm data from any web-enabled device without having to host anything on a server.

DATA COMMUNICATION- Performance data is delivered through standard network communication protocols to maintenance, reliability, and environmental protection stakeholders with role-based access and permissions.

SETUP & CONFIGURATION- Remotely setup and program, clear and reset alarms, install firmware upgrades. Personnel can also save, download and copy configurations between breakers.
