Install, Test & Commission
We’re changing the face of the grid, enabling energy flow more safely, smoothly and more efficiently, to make a net zero world possible.
Overview
Turnkey or selective site survey, design, build, install, test and commission for the full AVC chain including SAP provision and CDM roles to leave you with fully working and optimised automatic regulation of voltage at your substation, complete with manufacturer’s warranty.
Challenges
- AVC relays need to be correctly installed, setup and commissioned with an operating tapchanger
- Lack of specialist voltage control knowledge can create blindspots in the process
- Voltage control is only as good as the weakest link in the chain
- Voltage control is often thrown in with protection; the reality is very different
Solutions
-
Existing transformers
We can offer full turnkey service for retrofitting new AVC to existing transformers
-
Tapchanger mechanisms
As part of AVC installation we can bring tapchanger mechanisms (i.e. not the switching elements) back to working order
-
Site surveys
We can carry out site surveys and condition reports
-
Support your contractors
We can offer specialist expertise in AVC and tapchangers to support your generic substation contractors
-
Individual services
We can offer design, test & commission and troubleshooting as individual services
-
Availability
Available for new installs, refurbishments, accommodation of new generation and smart/enhanced AVC programmes
