Electrical and Electronics Measurements Measurement of Frequency and Power Factor Measurement of Power Factor
A pointer is connected to the spindle of a dynamometer type phase angle meter. The two light coils of the phase angle meter mounted on the spindle
1
carry equal amount of currents in phase with each other and develop torques opposing each other
2
carry unequal amount of currents in phase with each other and develop torques opposing each other
3
carry equal amount of currents at quadrature to each other and develop torques opposing each other
4
carry the load current and develop the magnetic field required for the meter
