1. Single line diagram of a power system and a distribution sub-station and basic functional study
of main components used in power systems.
2.
Make house wiring including earthing for 1-phase energy meter, MCB, ceiling fan, tube light,
three pin socket and a lamp operated from two different positions. Basic functional study of
components used in house wiring.
3.
Study the construction and basic working of ceiling fan, single phase induction motor and three
phase squirrel cage induction motor. Connect ceiling fan along with regulator and single phase
induction motor through auto-transformer to run and vary speed.
4.
(a) Basic functional study and connection of moving coil & moving iron ammeters and
voltmeters, dynamometer, wattmeter and energy meter.
(b) Run a 3-phase squirrel cage induction motor at no load and measure its voltage, current,
power and power factor. Reverse the direction of rotation.
5.
Study the construction, circuit, working and application of the following lamps:
(i) Fluorescent lamp, (ii) Sodium vapour lamp, (iii) Mercury vapour lamp, (iv) Halogen lamp and
(v) Neon lamp
6.
(a) Study the construction and connection of single phase transformer and auto-transformer.
Measure input and output voltage and fin turn ratio.
(b) Study the construction of a core type three phase transformer. Perform star and delta
connection on a 3-phase transformer and find relation between line and phase voltage.
