Synchronized phasor (synchrophasor) measurements for power systems are presented. This standard defines synchrophasors, frequency, and rate of change of frequency (ROCOF) measurement under all operating conditions. It specifies methods for…
A test procedure to provide a uniform method for investigating the effect of operating temperature on the life expectancy of liquid-immersed transformers is provided. The test procedures are intended to…
Methods of testing and evaluating dissolved gases in mineral based transformer oils found in Load Tap Changers (LTCs) are discussed and recommended in this guide. General types of LTC mechanisms,…
Revision of IEEE Std 1313.1-1996. The procedure for selection of the withstand voltages for equipment phase-to-ground and phase-to-phase insulation systems is specified. A list of standard insulation levels, based on…
A method for real-time exchange of synchronized phasor measurement data between power system equipment is defined. This standard specifies messaging that can be used with any suitable communication protocol for…
The testing of fault current limiters (FCLs) operating on condition-based impedance increase for AC systems 1000 V and above is described in this guide. Constant impedance series reactors and single…
