5 Line Parameters Calculators

Losses using Transmission Efficiency (STL)
Go Power Loss = ((3*Receiving End Voltage*Receiving End Current*(cos(Receiving End Phase Angle)))/Transmission Efficiency)-(3*Receiving End Voltage*Receiving End Current*(cos(Receiving End Phase Angle)))
Transmission Efficiency (STL)
Go Transmission Efficiency = (Receiving End Voltage*Receiving End Current*cos(Receiving End Phase Angle))/(Sending End Voltage*Sending End Current*cos(Sending End Phase Angle))
Voltage Regulation in Transmission Line
Go Voltage Regulation = ((Sending End Voltage-Receiving End Voltage)/Receiving End Voltage)*100
Impedance (STL)
Go Impedance = (Sending End Voltage-Receiving End Voltage)/Receiving End Current
Resistance using Losses (STL)
Go Resistance = Power Loss/(3*(Receiving End Current^2))
