Because there are differences between the Hydraulic and Transmission systems, it is absolutely critical that you use the right filter for each system.Īlthough it may seem as if will-fit elements will get the job done, will-fitters may recommend an element that won’t optimize your equipment and could potentially cause significant damage. They are designed to maximize hydraulic and transmission oil cleanliness, meet expected oil change intervals, and provide the best machine system protection available.

Total line resistance and inductance are assumed to be present in middle of the line.Cat® Hydraulic and Transmission Filters for off-highway equipment provide excellent component protection. In the nominal pi method total line capacitance is assumed to be lumped and divided into two halves to be connected across sending end and receiving end respectively. Nominal π Method in Medium Transmission Line I R is the receiving end load current per phase, In the nominal T method the capacitance of the line is assumed to be concentrated at the middle point of the line, and at both side half of line resistance and inductance is lumped. Nominal T Method in Medium Transmission Line X L is the inductive reactance per phase,ĬosΦ R is the receiving end lagging power factor, Here I R is the receiving end load current per phase, In this method capacitance is assumed to be lumped at receiving end. End Condenser Method in Medium Transmission Line Here it is clear that transmission efficiency depends on the receiving end power factor. Now it is clear that to transmit given amount of power, the load current is inversely proportional to receiving end power factor.Īgain in case of medium and long transmission line, So, considering three phase short transmission line, Now, for short transmission line, I R = I S = I We know efficiency of transmission line is Load Power Factor on Efficiency of Transmission Line

Power factor is leading, and then VR is decreased and goes to be negative.

Power factor is lagging or unity, and then VR is increased and goes to be positive.

Where, V s is the sending end voltage per phase and V R is the receiving end voltage per phase.Įffect of load power factor on regulation of transmission line: Voltage regulation of transmission line is defined as the ratio of difference between sending and receiving end voltage to receiving end voltage of a transmission line between conditions of no load and full load. V R is the receiving end voltage per phase.

V s is the sending end voltage per phase. Transmission efficiency is defined as the ration of receiving end power P R to the sending end power P S and it is expressed in percentage value.Ĭosθ R is the receiving end power factor.
