Substation Automation - Transducer


In substation automation, transducers convert AC/DC parameters (voltage, current or power) into output that is an equivalent representation of the input. They monitor critical loads and transmit a standardized signal used across the industry or a communication signal over interfaces such as UART or Ethernet to a central monitoring system.

A voltage/current transducer measures AC/DC input accurately (typically within ±0.5% of Full Scale) and produces a DC voltage/current (typically within ±0.2% of Full Scale). Power transducers measure both power and energy in both directions, indicated by the direction of flow of current. The transducer output can be scaled depending on the system architecture.
