General information
2.1. DEFINITIONS
Thefollowingdefinitionsareusedinthismanualforexplainingvariouselectrical
concepts, specifi cations and operations:
Peak Value:Itisthemaximumvalueofelectricalparameterlikevoltage/current.
RMS (Root Mean Square) Value: It is a statistical average value of a quantity that varies
invaluewithrespecttotime.Forexample,apuresinewavethatalternatesbetween
peakvaluesofPositive169.68VandNegative169.68VhasanRMSvalueof120VAC.
Also,forapuresinewave,theRMSvalue=Peakvalue÷1.414.
Voltage (V), Volts: It is denoted by “V” and the unit is “Volts”. It is the electrical force
thatdriveselectricalcurrent(I)whenconnectedtoaload.ItcanbeDC(DirectCurrent
– fl ow in one direction only) or AC (Alternating Current – direction of fl ow changes peri-
odically). The AC value shown in the specifi cations is the RMS (Root Mean Square) value.
Current (I), Amps, A: It is denoted by “I” and the unit is Amperes – shown as “A”. It is
the fl ow of electrons through a conductor when a voltage (V) is applied across it.
Frequency (F), Hz: It is a measure of the number of occurrences of a repeating event per
unittime.Forexample,cyclespersecond(orHertz)inasinusoidalvoltage.
Effi ciency, (
η
):ThisistheratioofPowerOutput÷PowerInput.
Phase Angle, (
φ): It is denoted by “φ” and specifi es the angle in degrees by which the
current vector leads or lags the voltage vector in a sinusoidal voltage. In a purely induc-
tive load, the current vector lags the voltage vector by Phase Angle (
φ)=90°.Inapurely
capacitive load, the current vector leads the voltage vector by Phase Angle, (
φ)=90°.In
a purely resistive load, the current vector is in phase with the voltage vector and hence,
the Phase Angle, (
φ)=0°.Inaloadconsistingofacombinationofresistances,induct-
ances and capacitances, the Phase Angle (
φ)ofthenetcurrentvectorwillbe>0°<90°
and may lag or lead the voltage vector.
