Power systems Studies

Electrical power systems require various studies to aid in system evaluation, reliability, safety, and ability to grow with production according to operating requirements. The system designer must decide what studies are necessary to ensure that the system operates safely, economically and efficiently for the expected lifetime. Some of the studies we have in our service proposal are:

Electrical Maintenance

We can offer our clients punctual electrical maintenance services or through annual service policies where we guarantee the continuity of your electrical supply.

Our electrical maintenance program aims to

Reduce costs and risks in your electrical system

Avoid production shutdown.

Increase the useful life of the electrical system

Our service consists of:

Review, inspection and cleaning of equipment

Electrical diagnostic tests

Commissioning of all equipment

Predictive Electrical Maintenance.

These are the actions we can perform to detect in advance any problem in the electrical system without making any shutdown or interruption of power supply. We recommend to apply the thermography service before the preventive maintenance service in order to be able to make the necessary corrections. Perform the service after the maintenance in order to verify the corrections made.

Visual inspection and supervision of monitoring equipment readings.

Thermography and hot spot detection.

Power Quality Measurements

Laboratory analysis of transformer oil

Preventive Maintenance

In order to keep the facilities and equipment in optimal operation, it is suggested to perform periodic preventive maintenance to avoid unexpected plant shutdowns and production losses.
