Dynamometer Type Wattmeter
A Dynamometer Type Wattmeter is an electromechanical device used for measuring electrical energy in a circuit. It operates based totally on the interplay of magnetic fields, generating a mechanical torque this is proportional to the electricity being measured. Here’s an in depth clarification of the operating principle of a Dynamometer Type Wattmeter:
Components of Dynamometer Type Wattmeter
- Fixed Field (Shunt Field) : This is a desk bound magnetic field that remains consistent all through operation. It is frequently created with the aid of a permanent magnet or a modern-day-sporting coil connected in parallel with the load.
- Moving Coil (Pressure Coil) : The moving coil is hooked up on a spindle and is free to rotate. It carries the burden present day, and the magnetic field it produces interacts with the fixed area, producing a torque.
- Control Spring : The control spring opposes the rotation of the moving coil and provides a restoring pressure.
- Pointer : The pointer is connected to the transferring coil and shows the dimension on a calibrated scale.
Working Principle of Dynamometer Type Wattmeter
- Fixed Field (Shunt Field) : The shunt subject produces a consistent magnetic discipline in the dynamometer wattmeter.
- Current Flow (Moving Coil – Pressure Coil) : The load present day flows through the transferring coil, growing a magnetic field round it.
- Magnetic Field Interaction : The magnetic discipline produced by means of the shifting coil interacts with the constant subject (shunt field), ensuing in a torque on the transferring coil.
- Torque Generation : The torque generated is proportional to the made from the cutting-edge and voltage in the circuit, representing the energy being measured.
- Rotation of Moving Coil : The torque reasons the shifting coil to rotate towards the control spring.
