Performance Assessment of Power Factor Capacitors.
Voltage effects: Ideally capacitor voltage rating is to match the supply voltage. If the supply voltage is lower, the reactive kVAr produced will be the ratio V1 2 /V2 2 where V1 is the actual supply voltage, V2 is the rated voltage. On the other ...
Explain THD & TDD in power quality.
The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the Fundamental frequency. TDD(I) = Total Current ...
Article 4.2.1F : Energy reading scaling ( Wh - Kwh - Mwh - Gwh) calculation
Elmeasure meter reads from zero WH and giving the perfect reading ... it is so simple - Meter starts with reading 1,2,3..etc... up to 9999 WH - [ To convert WH to KWH is Divide by 1000] . Example If the reading is 7000, divide it by 1000, It is 7 ...
