Electrical Installations and Maintenance

• The safety factors required by national and international standards
• The functional considerations that a designer has to take into account
• How new technology can impact on the design particularly power quality
• Safety requirements during installation, inspection and testing
• Inspection and testing techniques that affect the maintenance requirements
• How to improve productivity by improving the reliability of an installation

CONTENT

Preliminary Design Requirements

The design process requires consideration of the installation requirements with respect to the load characteristics, the circuit arrangements, and the source of supply.

• Building Services
• Purpose of an Installation
• Cables
• External Influences
• Transformers
• Compatibility
• Protective Devices
• Maintainability

Design Characteristics

To enable work to begin on any electrical installation a detailed specification is required. This specification will be based on the safety and functional requirements.

• Electrical Safety
• Cable Installation
• Terminations
• Wiring Regulations
• Inspection and Testing
• Cable Sizing
• Documentation

Designing an Installation

Building on the first two days of the training course this module puts into practice the theories developed.

• Single Phase Design
• Power Quality
• Three Phase Design
• Cable Requirements
• Protective Device Selection
• Installation Method
• Earthing and Bonding
• Source of Supply

Commissioning and Testing

The requirements for any maintenance routine begin during the design process and continue though installation into operation. In many countries there is also a legal requirement to maintain an installation in a safe condition.

• The Need to Maintain
• Test Results
• What is Maintenance?
• Documentation
• Introduction to Commissioning
• Harmonics
• Inspection
• Earth Leakage

Periodic Maintenance

After the initial verification of the safety and function of the installation it is necessary to ensure that safety remains effective throughout the lifetime of the installation.

• Maintenance Planning
• Periodic Inspection
• Equipment Reliability
• Complex Testing
• Categories of System
• Harmonic Analysis
• Safety Critical
• Records

Works, Services and Maintenance Personnel

TRAINING METHODOLOGY

The training methodology combines lectures, discussions, group exercises and illustrations. Participants will gain both theoretical and practical knowledge of the topics. The emphasis is on the practical application of the topics and as a result participant will go back to the workplace with both the ability and the confidence to apply the techniques learned to their duties.
