What it represents
A measuring relay responds to a measured electrical quantity and issues an output according to its configuration. Measurement inputs, auxiliary supply and output contacts may be separate terminal groups.
How to read it
- Identify the measured quantity before tracing the output contact logic.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Label measured input
- State auxiliary supply
- Reference threshold or setting record
A distinction that matters
A measuring relay is not simply a coil powered by the same quantity it measures.
