High-Voltage Circuit Breaker Services

High-voltage circuit breakers protect critical electrical equipment and help maintain reliable power delivery. MVA provides field support for breaker assembly, repair and maintenance during new installations, planned outages and equipment upgrades.

Breaker Assembly

MVA supports the assembly of high-voltage circuit breakers for new installations and equipment replacements. Our field team works from the equipment documentation and project requirements to assemble components, inspect the completed work and prepare the breaker for testing and commissioning.

Breaker Repair

When a circuit breaker develops a mechanical or operational issue, MVA can inspect the equipment, identify the concern and perform appropriate field repairs. Our team can coordinate breaker repairs with other work scheduled during an outage, helping customers make effective use of the time their equipment is out of service.

Breaker Maintenance

Scheduled maintenance helps identify wear, damage and developing issues before they affect breaker operation. MVA provides inspection and maintenance support based on the breaker type, its service history and the customer’s maintenance program. If an inspection reveals a concern, our team can help determine the next steps for repair or further evaluation.

Experienced Field Support for Your Substation

Breaker work often takes place alongside transformer maintenance, repairs or other substation projects. MVA’s field service team can help customers coordinate these activities through one provider, simplifying project planning and execution.
