We know electrical distribution systems and how to keep them working safely, delivering continuous quality power for your building.

Our testing equipment can detect load imbalance and harmonic distortions in your system, which can wreak havoc with computer operations and sensitive electronic equipment.

 While inspections are key, only servicing the equipment will ultimately reduce the risk of failure.


 Today 80% of all power problems occur on the customers’ side of the meter resulting in an estimated annual cost of $26 billion to businesses in North America.

Surely power quality, reliability, and efficiency issues are affecting your bottom line.

How can we help you?

We offer equipment, services, and supplies to an array of different facilities and clients. 

Environments of Care

SDM METRO can help make your hospital facilities compliant with all power, emergency, and standby power system requirements. This includes identification of essential electrical system components and connectivity.

Data Centers

Uninterrupted power supply is absolutely necessary in any digital environment. Loss of power, even for a fraction of a second, can lead to disastrous results. We can design, install, and maintain an appropriate uninterrupted power supply (UPS) for your facility.

Commercial Facilities

Time lost due to power outages or protective device failures can lead to big hits in your bottom line. Let us help you coordinate your facility’s electrical distribution, flagging any irregularities or coordination failures.
