MAINTENANCE OF LOW VOLTAGE EQUIPMENT

The electrical switchboard and all its equipment continue to age whether they operate or not. This aging process is due mainly to environmental influences and operating conditions. To ensure that low-voltage switchgear and especially circuit breaker retains the operating and safety characteristics specified in the catalogue for the whole of its service life, it is recommended that regular maintenance is carried out.

MAINTENANCE OF HIGH VOLTAGE EQUIPMENT

In any installation, the high-voltage switchgear equipment is designed to trip or otherwise open the electrical circuits in the event of malfunction of connected equipment. This automatic disconnect function is required to protect the personnel, the facility, equipment, and the utility providing the electrical service. Hence, to function properly when needed, all switchgear requires maintenance.

TROUBLESHOOTING FOR ELECTRICAL NETWORK

Our company provides this test as a high level predictive maintenance to monitor the condition of high-voltage switchgears with expert interpretation by our experienced engineers.

 

INFRA-RED THERMOGRAPHIC SURVEYS

IR SURVEYS

Our company uses infrared cameras to scan and detect thermal anomalies on switchboards. This high level predictive maintenance is used to monitor the state of health of switchboards carrying high currents.

DISSOLVED GAS ANALYSIS AND OIL TESTS

OIL & GAS TESTING

Insulating materials within transformers and electrical equipment break down to liberate gases within the unit. The distribution of these gases can be related to the type of electrical fault, and the rate of gas generation can indicate the severity of the fault. The identity of the gases being generated by a particular unit can be very useful information in any preventative maintenance program.

TROUBLESHOOTING ELECTRICAL NETWORKS

TROUBLESHOOTING

There’s more to a repair than simply throwing parts at a problem until it’s fixed. Our engineers take the time to analyze the root cause of each repair before we begin work. Just because a symptom highlights a part it doesn’t mean that part needs to be replaced. We’ll troubleshoot your system, find the cause of the problem, and then give you a set of possible solutions to choose from.
