TRAINING ACCOMPLISHMENTS
A trainee, on completion of a 4-year of training program, should have the knowledge and hands-
on skills in his/her trade as mentioned below:
H-1. ELECTRICIAN.
a. KNOWLEDGE
(1) Electrical Equipment. Familiar with theory, and working of various components of
electrical machinery - windings, commutators, slip rings, wiring, insulation, power control circuits
and other associated equipment. Must be capable of understanding electrical schematic diagrams
and solid state circuits. Must be familiar with the principles of operation of protective relays,
ground detection systems, remote control systems, excitation systems, measuring instruments,
rectifiers, control circuits for motor operated disconnects, air circuit breakers, oil circuit breakers,
transformers - power, potential & current, excitation systems, lighting arresters and H.V.
arresters. Be familiar with National Electrical Code and its application and conformance to all
jobs.
(2) Mechanical Equipment. Be familiar with the operating principles of hydraulic
turbines, governors, water and oil pumps, lubrication systems, gantry cranes, heating, ventilating
and air-conditioning (HVAC) systems, and other auxiliaries such as fishways and spillway
machinery.
b. SKILLS
(1) Main Generator. Must be able to assemble/disassemble, repair and maintenance all
components of the generator. Be familiar with the capacity, voltage and continuous output rating
of the generator. Be able to start and stop the generator and set the reactive power before
opening the generator breaker. Know operating and temperature limits of different components
of the generator and adjust annunciation systems accordingly.
(2) Voltage Regulator. By using schematic diagram, be able to describe operation of
voltage regulator (VR) and adjustments to system voltage. Know source of electric supply to
VR, purpose and use of voltage adjusting rheostat and voltage regulator transfer switch.
(3) Exciter. Must know winding arrangements of pilot and main exciters, both rotating
and solid state, and methods to control excitation current, purpose of excitation protective relays
and how they are connected. Be able to draw a simple diagram showing the excitation system and
generator field circuits.
(4) Transformer. Be familiar with all types of transformers (power, potential & current),
function of transformers, winding arrangements, cooling arrangements, and control circuits. Be
able to draw single line diagram and indicate various components of transformers and the way
they are connected.
