Symbols act as the language medium to understand the working process of the electricity metering equipment.

BS EN 62053-52 walks you through terms and definitions, symbols for the measuring, elements, symbols of principal units used for meters, marking of the measured quantity, symbols indicating the accuracy class, the meter constant and the insulating class, symbols for transformer-operated meters, tariff device symbols, symbols for auxiliary devices, symbols for details of the suspension of the moving element and warning symbol.
Thus, adopting standardized and globally recognised symbols can help in reducing miscommunication among the entities closely associated with electricity metering equipment.
