MEASUREMENT SETUP FOR A POWER LABORATORY MOTOR GENERATOR STATION

Measurement set up developed for autonomous motor generator stations f or an undergraduate power laboratory is described in this paper. Metho ds used to measure and display the various electrical and mechanical q uantities for easy observation by the students during the experiment a re described. A microcontroller-based instrument to measure speed, fre quency, load-angle and slip has been developed. The setup minimizes th e tangle of wires on the work table. It also allows the students to de vote their time more usefully to the experiment and observation of the characteristics itself. The setup has proven to be safe, functional d urable and instructive.
