Keep switchgear, transformers and protection systems performing across their whole lifecycle. Experienced service teams deliver preventive maintenance, condition assessment, diagnostics and repair for high-voltage equipment — from a single scheduled inspection to a planned maintenance campaign across an entire fleet.
Every intervention starts from the actual condition of your equipment. A structured condition checklist — type, serial number, operating-cycle counters, short-circuit operations and visual findings such as leaks or corrosion — lets the service team scope exactly the work that is needed. For transformers, insulating-oil services such as degassing, drying and regeneration can restore oil parameters and extend service life, in many cases while the unit stays energized.
For critical assets, optional on-call agreements provide 24/7 access to specialists in high-voltage and transformer technology, with defined response times for remote support and on-site deployment. A certified support center coordinates and documents every case through to closure.
Example: an operator of 3AP1 circuit breakers submits the condition checklist for several units, including serial numbers, operating-cycle counters and a noted gas leakage on one pole. The service center scopes a combined intervention — leak repair on the affected breaker plus preventive maintenance on the rest — confirms the outage window, executes on site and hands over a condition report with prioritized follow-up recommendations for each unit.
