  3. Special Energy Meter Various Checks CHECKS for DATA VALIDATION : • NOMINAL VOLTAGE CHECK • FREQUENCY • TIME CORRECTION • WATTHOUR CHECK • PREVIOUS WEEK DATA • ALGEBRAIC SUM

  4. Special Energy Meter Data Computing • RAW DATA IN WHr • MWhr = RAW DATA x CT RATIO x PT RATIO • PAIR CHECK DONE FOR MAIN/ CHECK/ STANDBY/ FICTMETERS ( ex. : for both sides of ICTs, Lines, GT side & Line side at ISGS.

  5. Reactive Energy Accounting Reactive Energy is measuredwhen system voltage is > 103% of Nominal Voltage< 97% of Nominal Voltage
