Maximum indication electricity meter - has kilowatt-hour meter, maximum indicator, current supply, controlled display elements and data output

摘要

The maximum indication electricity meter described comprises a kilowatt-hour meter (KW), a maximum indicator (MW), an electrical supply (SV), control devices for the display elements (AZ) and for a data output (DA), and a receiver of circulating commands (RE). These are integrated with a common housing. A time-base device is associated with the max indicator (MW) and is used to establish temporal interruption points. A battery constantly charged by the automatic line to an approx. max. capacity, is associated with the electrical current supply (SV). Alternatively, a memory, independent of the supply voltage, is used to memorise the measurement state at the time of a voltage drop. Cumulative counters fitted with stepping motors, or similar devices, act as display devices (AZ) to memorise the maxima.
