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. 517 $aIEEE Std 622A-1984: IEEE Recommended Practice for the Design and Installation of Electric Pipe Heating Control and Alarm Systems for Power Generating Stations 606 $aResistance heating 606 $aTemperature control 606 $aElectric heating 615 0$aResistance heating. 615 0$aTemperature control. 615 0$aElectric heating. 676 $a621.31042 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a996279421803316 996 $aIEEE Recommended Practice for the Design and Installation of Electric Pipe Heating Control and Alarm Systems for Power Generating Stations (Supplement to ANSI$93647533 997 $aUNISA
