Pre-Commissioning LV HV Systems by Oakes Power Services Ltd

Pre-Commissioning, also known as “Pre-functional Testing,” is an essential step in the installation and implementation of Low & High Voltage Electrical Power Systems – this process ensures that all components and cable accessories of the system are functioning properly and safely before the system is put into operation or “Commissioned“.

High voltage systems are critical to the operation of many industries, including utilities, manufacturing, data centres and commercial buildings. These HV systems are responsible for distributing and transmitting electrical power, and any failure or malfunction can have serious consequences, including injury, property damage, and loss of revenue.

Commissioning is a comprehensive process that involves testing and verifying the performance of all components in a high voltage system. This includes electrical and mechanical components, such as transformers, switchgear, protective devices, and control systems. The commissioning team will also verify that the system meets all safety and technical standards, and ensure that it is properly grounded and bonded.

In addition to ensuring the safety and reliability of the system, pre-commissioning can also identify potential issues and improve the overall performance of the system. This can save time and money by preventing costly repairs, mal-operation and downtime in the future.

Oakes Power Services is a leading provider of commissioning services for Low & High Voltage Electrical Power Systems – their team of experienced professionals have extensive knowledge and expertise in testing and verifying the performance of these systems using the latest tools and technology to ensure that your system is safe and operational

Oakes Power Services provide ongoing support and maintenance to keep LV HV power running smoothly.

By partnering with Oakes Power Services for your commissioning needs, you can have peace of mind knowing that your network is in good hands.

UKPN London Power Tunnel

The London Power Tunnels project will create a new 32km electricity super highway deep below the capital, which will help keep Londoners connected to safe and reliable electricity supplies. In some areas of the system power is transmitted via 6 sets of cables in trefoil arrangement, to safely contain these cables a new trefoil cable cleat was required.

Trefoil Cable Cleat

Ellis Patents Solution

Working directly with UK Power Networks (UKPN), Ellis Patents developed a trefoil version of its Centaur cable saddle, a bespoke product that not only allowed the preferred trefoil arrangement of HV cables to be run through a stretch of tunnel between New Cross and Finsbury Market, but also significantly reduce the number of supports required. An essential part of the development process was a product test in a short circuit test station in Prague. For the test the structure used in the tunnel was created and suitable cable shipped from the UK.

Summit Tunnel Track Renewal

Ellis Patents recieved a request from ISS Labour Ltd, whom required cable hangers for the track renewal programme at Summit Tunnel in Todmorden, Lancashire. Contractor CRSA Balfour Beatty had requested that the cable hangers be fitted onto the tunnel wall in order to replace the previous troughing route. The hangers were to be installed at 1m intervals, with the bottom bracket installed at rail height.

The Ellis Pegasus hanger offered a non-corrosive, lightweight & modular hanger option. The modular element allowed the 4 way hanger to consist of a combination of 100mm hooks and a control style bottom hook, to suit project requirements. ISS Labour selected Pegasus for its high quality. The 1200 units were supplied to a short project timeframe, to suit the track access timetable provided by ISS Labour.

Cable System Replacement Project

The client approached Ellis Patents for an upgrade to the cable systems at the USACE operated Fort Randall Dam, requiring a flexible system to be designed to cope with thermodynamic movement of the cables.

With no prior experience of such systems, USACE & Interstate Electrical Contractors Inc. contacted Ellis for assistance. The requirement was to install 12 cables onto an existing support framework which left limited space for installation

The cables could not be mounted in a rigid system using standard cable cleats, so Ellis developed a custom made variation of the Centaur Cable Saddle with a cable range of 68-73mm. With several bends and risers along the route, they also developed Anchor Clamps to secure the run and provided the Centaur Roller System to assist with installation.
