Calibration Of Single Phase Energy Meter Circuit Diagram

The meter which is used for measuring the energy utilises by the electric load is known as the energy meter.

Calibration of single phase energy meter circuit diagram.

But these are now being gradually replaced by electronic digital energy meters. The magnetic field produced by series magnetic in phase with the line current and magnetic field produced by shunt magnet is in quadrature with the applied voltage thus a phase difference exists between the fluxes produce by the two. Three phase energy meter connection wiring diagram meter board. Apply a load of 2 amps by switching on the load.

When the energy meter is connected in circuit the current coil carries the load current and pressure coil carries the current proportional to the supply voltage. In a typical residential single phase meter form 2s type the upper two lugs are connected to utility source and lower lugs are connected to the house branch circuit panel. Engineering circuit analysis duration. The stpm10 consists of two main sections.

If the meter is inserted in the socket upside down it will in fact rotate backward and subtract apparent energy usage from the register. 220v 10 50 60hz li polymer battery size mm. Electromechanical energy meters have been the standard for metering the electricity since billing began. Procedure for calibration and testing of single phase energy meter give the connections as per the circuit diagram above.

6 tft 640 480 power supply. The analog part is composed of preamplifier and first order sigma delta a d converter blocks a band gap voltage reference and low drop voltage regulator. The device can be implemented for peripheral measurement in a microcontroller based single phase or poly phase energy meter. Meter wiring diagrams for low voltage meter stations for in whangarei and kaipara.

The connection and circuit diagram of single phase 3 phase 4 wire kwh meter digital or analog energy meter from the supply to the main distribution board in the above graphics and diagrams p in incoming phase or live from the source supply voltage. Presented here is a simple energy meter using analog device s ade7757 chip for single phase 2 wire phase and neutral systems used in households. The energy is the total power consumed and utilised by the load at a particular interval of time it is used in domestic and industrial ac circuit for measuring the power consumption. The meter is less expensive and accurate.

Apply 220v a c to the pressure coil circuit by means of phase shifting transformer. 1 electrical parameters accuracy class.
