Electrical Transmission ,Scale Transmission,Electrical Power Transmission Line Trainer,electrical transmission


The trainer should be design to perform learning aspects of the  electrical transmission line.  provided for easy measurement of voltage, current, power, power factor. Students can perform various experiments like short, medium and long transmission line and their behavior. Also one of the important experiment which can be per for med with this training system is Ferranti Effect.

Technical Specification :

The trainer should consist of the following :

· Three Phase Power Supply Unit

· Fault Current Circuit Breaker

· Transmission Line Model

· Power Meter

· Power Factor Meter

· RMS AC  Ammeter

· RMS AC Voltmeter

· Resistive Load

· Capacitive Load

· Inductive Load

· Earth Fault Compensation

The effect of power factor improvement or the efficiency of transmission :

– Operation of lines in parallel using various line connection configurations.

– Locus diagram of Vs for short line with constant current and varying load power factor.

– Verification of a power line on a short line characteristic using a unit p.f variable speed.

– Short line receiving end chart showing load power  and load vars using unit and zero power factor load.

– Verification of performance chart for a given power limit.

– Determination of transmission efficiency.
