Electrical Power Laboratory

ELECTRICAL POWER LABORATORY

DEPARTMENT OF ELECTRICAL AND ELECTRONIC ENGINEERING

The practical aspect in the power engineering undergraduate studies is taking increasing importance because of the requirements of the industry to employ engineers, not only with an important theoretical background But also with a practical experiment. Accordingly, our laboratory is designed to facilitate elegant learning activities on power engineering studies.

The following were designed to introduce the important facilities and equipment that the power laboratory uses,

Transmission Line Model

The laboratory is equipped with TERCO MV1420 Transmission Line Model corresponds to a power transmission line of a length 136 km, voltage 77 kV, amperage 100 A, power rating 13 MW. With this setup module we are able to perform the following studies.

  1. Measurements of characteristic data, resistance, reactance and capacitance of a line.
  2. As transmission line: Measurement of voltage drop and losses for different loads.
  3. For two-phase and especially three-phase short circuit measurements with two three phase transformers, one at each end.
  4. For single-phase and two-phase earth fault measurements.

The network model also can be used to complete a series of experiments with transmission lines.

Single Phase Transformer Windings

Our laboratory offers all the facilities to make the single-phase step – down transformers as accurately as possible according to the requirements given to the students.

Students are instructed to setup the transformers they need by following these steps.

  1. Selection of core material and core construction type.
  2. Finding no. of turns, Volt-Ampere rating, appropriate area or dimensions of the core laminations.
  3. Selecting suitable copper wire for transformer winding based on the current rating of the transformer.

Also, adequate facilities have been developed in the laboratory using FY-730 computer-controlled coil transformer winder for winding the transformers as required.

Single Phase Transformers

With the number of single-phase transformers and different loads for laboratory use, students are able to examine the design of single-phase transformers to study the voltage and current ratios of transformers and also the voltage regulations of the transformers with different loads. Students will also be able to learn the equivalent circuit parameters of transformers by performing the required tests on transformers.
