Multiple partial discharge source discrimination with multiclass support vector machines

作者:

Highlights:

• Different types of partial discharges are created with test objects in laboratory.

• Their frequency content depends on the type of discharge and other external factors.

• An SVM extracts characteristics from the power spectral density of the pulses.

• Noise, corona, internal and surface discharges have different characteristics.

• The differences are used to classify discharges and separate them from noise.
