MW TRANSDUCER (Active Power Transducer (Watt)) RELAY CONFIGURATION AND SETTINGS

MW TRANSDUCER (Active Power Transducer (Watt)) RELAY CONFIGURATION AND SETTINGS

The active power in a load represents the energy being converted into non-electrical forms such as heat, light, and mechanical work. It is represented by the voltage across the load multiplied by the in-phase component of the current through the load. Active power transducers obtain a power signal from the input current and voltage signals by passing them through an electronic multiplier. When this power signal is averaged it represents the true power independent of phase angle and wave shape. Single-phase transducers have a single multiplying element whilst three phases transducers have up to three multiplying elements depending on their type. A variety of power transducers are available to suit various purposes. The simpler types, whilst they are cheaper in price, often rely on some assumption being made which affects their accuracy.

Megawatt Transducer Failure

"If the MW signal indicates an excessive negative value, the megawatt transducer is assumed to have failed. The MKVIe reverse power sequencing will be faulted and prevented from opening the breaker. This condition is annunciated in an alarm to the operator."
