POWER TRANSMISSION AND DISTRIBUTION EXPERIMENT SYSTEM

Description

POWER TRANSMISSION AND DISTRIBUTION EXPERIMENT SYSTEM

Desription :

Using the Power Transmission Line trainer set it will be possible to assemble an absolute power transmission system. From a transformer with tapping switch to the power circuit breaker and 415V power transmission line model, including line termination with surge impedance. Various experiments can be are carried out on this power transmission system, no load operation with natural load, asymmetrical and asymmetrical short circuit, parallel and series compensation of the transmission line as well as neutral-point connection.
