The recommendations include selection of control and alarm systems, accuracy considerations, local control usage, centralized control usage, qualification criteria of controls and alarms, and calibration and testing of controls and alarms. The purpose of this recommended practice is to provide recommendations that will ensure design consistency and reliable operation of electric pipe heating control and alarm systems which in turn will ensure that piping systems' fluids will be available for use not only during station operation but also during normal shutdown.IEEE Std 622A-1984: IEEE Recommended Practice for the Design and Installation of Electric Pipe Heating Control and Alarm Systems for Power Generating StationsResistance heatingTemperature controlElectric heatingResistance heating.Temperature control.Electric heating.621.31042NjHacINjHaclDOCUMENT9910135989903321IEEE Recommended Practice for the Design and Installation of Electric Pipe Heating Control and Alarm Systems for Power Generating Stations (Supplement to ANSI3647533UNINA
