Peak detection of the voltage sine wave shall not be permitted to avoid inaccurate tap switching due to input voltage distortion. Line Voltage Regulation and Correction Time: Output regulation shall be +5%, -6%, given an input voltage variation of -30% to +30% for nominal, when within +/-5% of the nominal frequency. The Micro card shall be equipped with both “Input Out of Range” , “Output Out of Range” indicators light shall be provided on the meter face to indicate that the input/Output voltage or frequency has exceeded acceptable limits. Metering: A digital input meter shall be provided to display line voltages, line currents, frequency, kVA, kW, and power factor. MAKE PARTNER/ ABB/ CG as approved by GE.
