A new type of transducer is described which enables the continuous monitoring of transmission line current voltage, real and reactive power, and which can also be used to operate the relays necessary for the protection of the line. The new transducer is designed as an integrated unit containing both the current and voltage sensors, thus eliminating the need for conventional current transformers and voltage transformers. The signals from the two sensors are processed using a simple electronic circuit which brings them to a level suitable for metering and relaying purposes. An analogue to digital interface enables the transducer to be connected to a computer for continuous data acquisition storage and monitoring. Due to its geometry and its simple structure, the transducer is ideally suitable for integration into a gas-insulated busbar duct system.
