FAQs - Power Circuit Monitoring
Power circuit monitoring for server rooms, data centres and other building circuits where you want to measure and record power parameters.
A branch circuit is part of the electrical distribution wiring within a building. The branch circuit is connected to an individual Way within a distribution panel and protected by an individual circuit breaker or fuse. The branch circuit provides the electrical power and energy to connected devices.
Branch monitors record and monitor electrical parameters within an individual electrical circuit. The most commonly measured parameters including electrical supply voltage (V – volts), amperage (A – amps), power factor (pF), real power usage (W – Watts or kW) and energy usage (kWh – kilo-Watt hours).
A current transformer (CT) is a device used to measure electrical parameters within a circuit using electromagnetic induction. Sometimes referred to as a CT clamp, the electrical supply cable to to be monitored is fed through the centre of the CT core or more commonly the CT core ‘splits’ and can be connected around the cable. CT cores are sized for various voltages (V) and amps (A) have to be suitably sized for the cable size, voltages and current in use.
