The Correll Group has an in-house training facility located at our head quarters in Skelton, in the North East of England for HV Operations.​

The training facility includes a bespoke mock-up training area, enabling our technicians to become familiar and competent with installation and maintenance systems prior, during and on-completion of a project.​

Our set –up includes:​

• Siemens 33kV Gas Insulated Switchgear (3 cubicles)​
• HV cabling (subsea, XLPE, EPR)​
• Hang-off systems​
• Containment​
• Mock transformer bushings​
• Gantry levels (as found on TP’s & WTG’s)​
• Cable pulling equipment​
• Fibre optical cables​
• Fibre optical junction box (with cassettes & bulk-heads)​

Having the Siemens GIS equipment as part of our set-up, enables us to train our technicians on other switchgear related activities.​

• Switching operations (circuit breaker, disconnector & earthing)​
• Secondary injection testing​
• With the subsea and transformer cables connected to the GIS, we can simulate conditions to train our technicians in the following techniques:​
• Insulation Resistance testing​
• Sheath testing​
• TDR testing​
• Very Low Frequency testing​
• Partial Discharge testing​
• Optical Time Domain testing​

Further developments and offerings are planned in 2022, with the addition of control room asset monitoring, high voltage safety rules, construction support and services operations & maintenance.
