Electrical Engineering ⇒ Topic : Errors of dynamometer wattmeters
Errors. A wattmeter may not give true reading due to several sources of errors such as
(i) error due to connection of potential coil circuit
(ii) error due to inductance of potential coil
(iii) error due to capacitance in potential coil circuit
(iv) error due to stray fields and
(v) error due to eddy currents.
