Medium-Voltage Switchgear for Campus and Utility Intake
Medium-voltage (MV) switchgear and ring main units handle utility intake and distribution for large campuses and data centers, typically up to about 24kV. Platforms such as Schneider PremSet, SM6, and RM6, with EvoPacT vacuum breakers and Easergy protection relays, provide shielded, reliable MV distribution. Comp-Utility specs, installs, and services medium-voltage switchgear across Central Texas.

Reliable Power at the Front Door of the Facility
Large data centers and campuses often take power at medium voltage and distribute it before stepping down. MV switchgear and ring main units provide the breakers, protection, and switching for that intake and distribution, with shielded, solid-insulation designs for reliability and safety.
Comp-Utility specifies, installs, tests, and maintains MV switchgear, coordinating protection with the rest of the electrical system.

Frequently Asked Questions
What is medium-voltage switchgear?
Medium-voltage switchgear is electrical equipment that switches, protects, and distributes power at medium voltage, typically up to about 24kV, often at a facility's utility intake. It includes circuit breakers or switches, protection relays, and metering. Large data centers and campuses use MV switchgear to receive and distribute utility power before transformers step it down to low voltage.
When does a facility need medium-voltage switchgear?
A facility needs MV switchgear when it takes utility power at medium voltage, which is common for large data centers and campuses with high total demand, or when distributing power across a large site at medium voltage before local step-down. Comp-Utility's engineers determine whether your load and utility service warrant MV distribution.
What is a ring main unit (RMU)?
A ring main unit is a compact medium-voltage switchgear assembly used to connect into a utility ring or loop distribution, providing switching and protection for a transformer or feeder. RMUs like the Schneider RM6 are common at the intake of larger facilities. Comp-Utility specifies and installs RMUs as part of MV intake design.
What protection do MV systems require?
MV systems require protective relays that detect faults and operate breakers to isolate them quickly, coordinated with the utility and downstream protection. Digital relays such as Schneider Easergy provide this protection and control. Comp-Utility specifies and tests protection relays and coordinates the scheme so faults are cleared safely and selectively.
How is medium-voltage switchgear maintained?
MV switchgear maintenance includes inspection, insulation and contact testing, vacuum breaker testing, protective relay testing, and thermography, performed by qualified personnel following strict safety procedures because of the voltage. Comp-Utility maintains and tests MV switchgear and documents results, coordinating any required outages carefully.
Do you coordinate MV work with the utility?
Yes. MV intake design, installation, and switching often require coordination and approval from the serving utility, including protection coordination and metering. Comp-Utility's engineers work with your utility on the intake design and requirements as part of a turnkey project, so the MV system meets utility and code requirements.
