A recording wattmeter measures active power and records it according to the specified instrument.

## What it represents

A recording wattmeter measures active power and records it according to the specified instrument. The schematic identifies voltage and current inputs while the logging settings belong in the instrument configuration.

## How to read it

- Check input phase relationships and the recorded power sign convention.
- 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

- Show voltage and current inputs
- Reference CT/VT ratios
- Identify recording interval

## Important distinction

A wattmeter records power at a time or interval; an energy meter accumulates power over time.
