We provide specialized technical support for substation maintenance, electrical testing, and commissioning, helping reduce risk and keep critical operations running safely.
When a substation fails, the entire operation stops
Electrical substations are critical infrastructure for many industrial and commercial operations. A failure can affect production, personnel safety, operational continuity, and high-value equipment.
That’s why proper maintenance, technical testing, and expert assessment are essential to reduce risk and prevent unexpected outages.

Substation services FAQ
What do your substation services include?
Our substation services cover preventive and corrective maintenance, electrical testing, fault diagnosis, commissioning of new or modified equipment, and inspection of transformers, breakers, switchgear, protection systems, and grounding.
How often should an industrial substation be serviced?
As a general guideline, at least once a year. Substations that feed critical processes, run near full load, or operate in dusty or humid environments may need shorter intervals. We review your equipment and history to recommend a schedule.
Can substation work be done without stopping the plant?
Inspections and thermography can be done with the substation energized. Cleaning, tightening, and most electrical tests require a planned outage; we coordinate the switching sequence and the timing with your team to keep the shutdown short.
Do you work on medium- and high-voltage substations?
Yes. Our crew works on medium- and high-voltage substations for industrial and commercial customers, following lockout and switching procedures suited to each voltage level.
What happens if my substation fails outside business hours?
Call our 24/7 emergency line. We send a crew to diagnose the failure, make the installation safe, and restore service as soon as conditions allow.
Do you commission new substations or equipment?
Yes. Before energizing new or repaired equipment we verify connections, protection settings, insulation, and operation, so the system starts up safely and with documented results.
Which standards apply to substation maintenance in Mexico?
Electrical installations in Mexico follow NOM-001-SEDE-2012, and maintenance safety is covered by NOM-029-STPS-2011. We work in accordance with the NOM standards that apply to each installation.
What information do you need for a quote?
Tell us the substation voltage and capacity, the number of transformers and breakers, the location, and the type of service you need. Photos of the nameplates help us prepare an accurate quote for your substation services.
