CONTROL OR REGULATION OF ELECTRIC MOTORS, ELECTRIC GENERATORS OR DYNAMO-ELECTRIC CONVERTERS; CONTROLLING TRANSFORMERS, REACTORS OR CHOKE COILS

Introduced: September 1968

Description

H02P encompasses control and regulation systems for electric motors, generators, and dynamo-electric converters, as well as control of transformers, reactors, and choke coils. This includes speed control, torque regulation, power factor correction, starting circuits, braking systems, and protective devices for rotating electrical machinery and passive power components. The classification covers analog and digital control methods, feedback mechanisms, and conversion of electrical parameters to achieve desired operational characteristics across industrial, transport, and utility applications.

Of 27 combined children, 18 exist in both systems.

7 codes are CPC-only extensions, 2 exist only in IPC.

Note: 7 CPC extensions are marked as secondary classification only.

10 shared codes have differing titles between IPC and CPC.
