High Voltage

Consultancy and High Voltage for ISG

A case study about our expertise at work in the Industrial sector

Power Management Design and Build was called in by KpH Environmental Services Ltd to work on the 11kV network for 20 Old Bailey, London EC4M 7BH, a prestigious office address opposite the Central Criminal Courts in London. 

Kph Environment Services was commissioned to remove mechanical and electrical services ahead of the new fit out works by ISG plc, the prime contractor for Blackstone.

Our project included visits by one of our Senior Authorised Persons and one of our Authorised Persons to assess the status of the high voltage switchboard which fed the 4 x 11kV transformers.

Switching operations were undertaken to suit the schedule of works. One 11kV transformer was isolated and earthed and we issued the necessary documentation to allow the safe disconnection and removal of the associated low voltage switchboard. 

A second transformer was restored to operation so that there would be sufficient lighting on the upper floors to allow strip out works to be undertaken safely. All of the High Voltage switching operations were completed across a Bank Holiday weekend.

The result was the successful completion of the electrical services for KpH Environmental Services, enabling ISG to make a prompt turnaround to the £59million scheme.

Consultancy and Installation for BBC World Service

A case study about our expertise at work in the Media and Entertainment sector

Power Management Design and Build was flown out to Cyprus by the BBC for an urgent intervention they needed on the power system that supplied the British East Mediterranean Relay Station (BEMRS) at Zygi, east of Limassol. The engagement came from a recommendation made by Andy West Associates.

The transmitter station is one of the largest of its kind in the world and broadcasts programmes created by BBC World Service in London.

Daily at 1400 GMT all transmitters are required simultaneously which means the working environment had to be very carefully managed without delays in reinstating any transmitter.

The project included replacing the vacuum bottle in the GEC 11kV circuit breakers, some of which had completed over 30,000 switching cycles.

We were responsible to oversee and sign the project off on behalf of the BBC, having satisfied ourselves that the team, including Areva T&D and site personnel, had completed the works. The intervention was delivered successfully and ahead of deadline.

High Voltage for Pinewood Studios

A case study about our expertise at work in the Media and Entertainment sector


Power Management Design and Build was asked by Andy West Associates on behalf of Pinewood Studios to provide an 11KV network and switchgear specification and design. 

Having invested several million pounds in a new 10MVA connection Pinewood needed a design for an 11kV distribution system for the entire Pinewood Studios site.

We specified a new 11kV switchboard and designed a new 11kV ring main. Previously, Pinewood needed to use their own on-site generator for peak lopping which proved noisy, expensive and operationally impractical. The newly specified switchgear utilised vacuum switches to replace SF6 switches which were not environmentally friendly. 

Our experts worked alongside the AWA electrical engineers to complete a critical project for this world renowned studios where TV and feature films are made, for example James Bond and Star Wars movies amongst others.
