In dynamometer wattmeter, the pressure coil is designed for having a low value of resistance so that the high value of current passes through it. This current produces the deflecting torque on the moving coil.
In a low power circuit, the value of the current is high, and that of the power is low. This high-value current causes the error in the wattmeter reading. To reduce this error, the compensation coil is used in the circuit.
Compensating coil has an equal number of turns of the current coil and is connected in series with a voltage coil or pressure coil. It carries current equal to the sum of two currents i.e. load current plus pressure coil current. The pressure coil is placed such that the field produced by the compensating coil is opposed by the field produced by pressure coil as shown in the above circuit diagram.

Explanation:
The dynamometer wattmeter is an instrument used to measure the power in AC circuits. It works on the principle of the mutual induction between two coils. The two coils are the voltage coil and the current coil. The voltage coil is connected in series with the load, and the current coil is connected in series with the supply.
Compensation Coil:
The compensation coil is used to compensate the mutual inductance between the voltage and current coils. It has an equal number of turns of the current coil and is connected in series with the voltage coil. The compensation coil produces a magnetic field that opposes the magnetic field produced by the current coil. This opposition reduces the mutual inductance between the current and voltage coils.
Working:
The current coil produces a magnetic field proportional to the current flowing through it. The voltage coil produces a magnetic field proportional to the voltage across it. The magnetic field produced by the voltage coil interacts with the magnetic field produced by the current coil, and the resultant torque on the moving coil is proportional to the product of the current and voltage.
Conclusion:
The compensation coil is used to compensate for the mutual inductance between the voltage and current coils. It has an equal number of turns of the current coil and is connected in series with the voltage coil. The compensation coil produces a magnetic field that opposes the magnetic field produced by the current coil. This opposition reduces the mutual inductance between the current and voltage coils, and the resultant torque on the moving coil is proportional to the product of the current and voltage.
