Power Transformers

Power transformers are essential items in a substation and should be preserved and maintained through inspections and tests at regular intervals.
The LPEng Engineers and Technicians bring the know-how of these devices and equipment with respect to testing, detailed inspections, corrective field service, assemblies and commissioning.

High Voltage (HV), Medium Voltage (MV), and Low Voltage (LV) Circuit Breakers

The circuit breakers perform the functions of maneuvering and protecting the electrical systems and equipment.
The protection system is made up of the combination of transformer instruments, batteries and rectifiers. Keeping these sets reliably requires skilled, trained, and constantly update labor.
The LPEng have available the necessary resources to ensure a good assistance in all these aspects.

Power Cables

The power cables and their connections or terminations should be inspected and tested regularly because it is through them that the equipment is interconnected and promote supply to the loads.
The greatest number of faults is located in terminations and bushings and the LPEng has the appropriate equipment for detecting these problems.

Panels and Cubicles

The panels are responsible for controlling and monitoring the equipment and contain the meters, while the cubicles house the medium voltage equipment.
Connection inspection, testing, cleaning and retightening are activities that should be done regularly
