- Objectives
-
This course will raise the awareness of the hazards and dangers associated with electrical equipment and machines and demonstrate safe methods of work accordingly.
On completion of the course delegates will be able to diagnose simple electrical faults and have an understanding of the possible causes and carry out necessary isolations and repairs, whilst understanding their limitations and hazards associated with the electrical systems and machines.
- Content
-
Over the course of the week, delegates will complete the following modules, timescales depend on delegates' understanding and speed at which practical sessions are completed
Day 1
Basic electrical safety
Current legislation
Safe isolation procedures
Safe systems of work
The safe use of multi meters (and their limitations)
Proving for "dead"
Ohms law and basic terminology
Conductors, Insulators, Volts, Amperes
Ohms, Watts AC and DC
The effects of current flowing in a conductor
Single phase and generation and distribution systems
Simple series and parallel circuits
Practical exercises will include the measurement of volts, amps and ohms using multi meters. Proving for “dead” and maintaining isolations. Wiring one way, two way and intermediate lighting circuits.
Day 2
Fuses and fuse types up to B.S 88 pt 2 and M.C.B's
Basic measurement of fault levels
The importance of earthing and fusing the live conductor
Basic diversity and discrimination
Electrical shock and the effects on the human body
Methods of reducing the risk of electrical shock
R.C.D's safe working practices and reduced voltages (110v C.T.E)
Three phase generation and distribution systems
The function of the neutral and earth conductors
Practical exercises will include blowing fuses, the measurement of fault levels on various parts of the system, "hands on" demonstrations of transformer operation, three phase generation.
Day 3
An overview of the electrical distribution network up to the customers supply
Three phase configurations star and delta
The operation and testing of the three phase squirrel cage induction motor
The safe use of a insulation resistance tester (megger)
Phase balance and earth continuity testing
Practical exercises will include the bench testing of three phase induction motors and the isolation, disconnection, reconnection and dynamic testing of 415v induction motors.
Day 4 and 5
Examine the component parts of a direct on line motor starter panel to include:
Isolators, fuses, contactors, overloads
M.C.B's, push buttons, switches, relays
Investigate and understand basic schematic diagrams
Wire the above panel, with the power, control and indication circuits
Static and dynamic testing of the panel at the relevant stages
