Maintenance managers' guide overview

This Guide offers qualified PQ information relating to several different plant or office building scenarios in terms of the power system measurements required to understand and manage the following typical cases:

• Premature wear or breakdown of electrical equipment
• Unexpected circuit-breaker tripping
• Electrical equipment over-heating
• Inconsistent behaviour of components due to inadequate earthing systems
• Loss of voltage gensets
• Incorrectly rated voltage gensets
• Malfunction of electrical equipment
• Lack of synchronisation between equipment
• Low electrical insulation leading to high risk of breakdowns

Each individual Guide will be based on this check-list:

• a general description of the malfunction;
• what is expected to be achieved by effective measurement;
• the choice of measurement instruments at our disposal (from the basic multimeter to more sophisticated Power Quality analyzers, oscilloscopes, electrical multitester, current probes, infrared thermal cameras, etc.). Their individual use will be justified according to the type of measurement required;
• where to position measurement equipment to make sure useful information is captured;
• illustrations of data management;
• the diagnostics directly related to the measurements

To summarise, Leonardo ENERGY presents these Guides to Maintenance Managers to assist in choices you have to make on a daily basis both to make sure the “lights do not go out” and as importantly that your plant is running as reliably and efficiently as it should. The choices will range from basic, less specialist every day measurement to more complicated approaches that may require more specific expertise..

Adopting the correct electrical installation measurement regime will contribute to improving the end users’ electrical energy efficiency as well as significantly reducing if not eliminating predictable plant or power system failure.
