FAQ

What is medium voltage electrical service?

Medium voltage electrical service refers to power distribution systems typically operating above 600 volts and used to deliver electricity across large commercial and industrial facilities. These systems require specialized design, installation, testing, and maintenance to ensure safe and reliable operation.

When does a facility need medium voltage work?

A facility may need medium voltage services when expanding power capacity, upgrading electrical infrastructure, experiencing repeated outages, or transitioning to a customer-owned primary system. Medium voltage work is also required for new construction projects and planned maintenance programs.

What is a primary electrical system?

A primary electrical system is the portion of a power distribution system that operates at medium voltage before electricity is stepped down for use within a building. These systems typically include utility feeds, transformers, switchgear, and distribution cables.

How often should medium voltage systems be tested?

Medium voltage systems should be tested regularly as part of a preventative maintenance program. Industry standards and manufacturer recommendations typically call for testing every one to three years, depending on system usage, environment, and criticality of operations.

Electrical Testing & Maintenance Services

Can medium voltage work be done without shutting down operations?

In some cases, medium voltage work can be performed with limited disruption using planned outages, temporary power solutions, or phased installation strategies. However, certain repairs and installations may require a full shutdown to ensure safety and proper execution.
