High Voltage Transformers – Vacuum Filling – Fast Track Power
Vacuum filling using dielectric oil or gas are essential for the proper operation of high-voltage equipment and energy facilities. Our engineering teams and field technicians perform vacuum filling for clients who require equipment and services for high-voltage substations and fast-track power plants. We complete vacuum filling following repairs, routine maintenance and the installation of new equipment.
Oil filling is one of the final steps that must be completed before individual transformers and entire substations are operational. We have the equipment and on-call staff needed to handle jobs with fast-track deadlines. Our technicians inspect, install and assemble transformers and other high-voltage equipment. We can complete vacuum filling services exclusively or as part of the installation process. Complete and limited services are available depending on the configuration of transformer shipment.
High-Voltage Vacuum Filling
Our self-contained vacuum units are capable of filling high-voltage transformers with capacities ranging from 500 kV to 550 MVA. Units can be filled according to specifications provided by the manufacturer, the client or our engineering team. The following process ensures that oil levels support safe and efficient operation.
- Transformer tanks are put under a high vacuum according to the unit type.
- Oil is filtered and heated to ensure complete dehydration and degasification.
- Purified oil is pumped into the transformer at optimal rates.
- Temperature, quality and pressure are monitored during the filling process.
We also offer filling and reclamation services for high-voltage circuit breakers that use SF6 gas. Efficient filling services prepare new equipment for long-term operation. We process oil and use vacuum dehydrators to restore dielectric strength. When required, our vacuum equipment can drain transformer oil and prepare units for repairs and upgrades. Combining services allows clients to minimize downtime and limit expenses.
