Multi-rate meter and time switch constitutes Indexer

Limited period of time each day measuring energy to electrical energy at different rates denominated tables, also known as the timeshare interest rate level meter or meter . Multi-rate watt-hour meter has a number of degrees , respectively, in each of degrees within the prescribed period of time to work out the different measurement periods  Circuit breaker energy tariffs . Using multi-rate watt-hour meter peaks and valleys of electricity can be measured separately , namely billing, is an economical means to regulate the electricity load with effective measures . Multi-rate watt-hour meter energy meter by the agency ,  electric meter  protractor and time switches. The active power integrated over time to measure the AC circuit functional capacity of the meter , also known kWh meter or meter . Power meter is widely used, can be used to measure the energy emitted power plants and a variety of user consumption of electricity , and as  mcb circuit breaker  and collection of electricity basis. Meter is divided into single -phase energy meter and three-phase energy meter , there are some special-purpose power meter, such as multi-rate meter , largest scale , reactive power meter, DC energy meter , standard meter and so on. Induction single-phase energy meter system structure shown in Fig. Voltage element 1 and the current element 2 from the corresponding coil and core components.
