maintenance service with a team
of highly trained engineers.

HVSM Technicians are trained and experienced to perform Routine Maintenance and Emergency Repair of Industrial Electrical Power equipment and systems. It is important to maintain the equipment in a safe, reliable and fully functional state which can be done with regular maintenance.

Because your HV/MV Equipment and System is critical to plant reliability and because often there is no redundancy a failure can result in an unwanted shutdown of the complete plant.

Maintenance can be categorised into the following types

•  Routine maintenance   •  Corrective maintenance   •  Fault Repair 

Routine Maintenance

Sometimes referred to as predictive or preventive. This type of maintenance which should be cyclical is often planned on the bases Of the criticality of the plant. Best practice would dictate that some maintenance should be done at least once per year.

Corrective Maintenance

Following the identification of problems during routine maintenance follow up actions are identified. Any parts that may be required for repairs are sourced and a plan put in place to rectify the problem.

Fault Repair

HVSM Provide a comprehensive round the clock emergency response to the industry. We carry a large range of cubicle equipment spares which enables us to get customers supply reconnected ASAP

Oil Analysis

As part of the preventive maintenance service for transformers we provide an 'Oil Quality" monitoring service where a sample of oil is taken from the transformer and sent to a laboratory for analysis. The tests carried out are DGA and Oil quality with as many as 12 different elements being measured and analysed. When a problem is identified from the first sample further oil analysis and electrical tests can be done to establish the exact source of the problem.

The advantage of this is to give an early warning as to the health of the trafo. The results are mapped from one test to the next so that trends are established. Our expert maintenance team analyse the results. In the event of problems, we discuss and advise customers as to the best course of action required. Oil analysis is also an important function during commissioning of new transformers as it acts as a benchmark against which future analyses can be compared.

Having a preventive maintenance program in place can reduce the risk of unplanned outages. According to the IEEE this can be as high as 65%
