Our Services

Detailed Protection & Control Design

We have the ability to take a ‘high level’ conceptual design and turn it into a detailed working solution. This may either be as a stand-alone system or integration into an already existing and operational system. We will produce design outputs typically in the form of drawings such as Single Line and Key Line Diagrams, Schematic Diagrams, Wiring Diagrams, Cable Block Diagrams, Cable Schedules, Logic Diagrams and Fibre Optic Cable Diagrams to integrate and connect the system together.  We would also consider any ‘staged’ work and system constraints especially when integrating with existing arrangements to ensure the system is installed with minimal disruption and outage time.

Protection & Control Cubicle Design

We will design the system to be located into a suitable housing (cubicle or wallbox etc,) as required by the clients specifications and site requirement. We will produce design outputs typically in the form of drawings such as General Arrangements and Wiring Diagrams.

Project Management

TES offer project management services for a wide range of green and brownfield transmission projects. TES will manage, monitor and control projects from the very start to handover and closeout. Our proactive project management team provide leadership while monitoring and reporting HSE&Q, time, cost and quality.

We can provide dedicated protection settings engineers who can analyse the system parameters and provide detailed setting reports and relay setting files to suit. We can also provide DC and AC loading calculations and Voltage drop calculations. TES Engineers are TP107 authorised and can provide 1st and 2nd check as well as livelink flows to suit your needs.

Site Visit Reports & FDS

We can provide detailed or ‘high level’ functional design specifications, Functional Overview drawing and reports in a format to match the customers’ expectations. Additionally, we can also provide comprehensive site visit reports and Design Indent Documents if required.

We have following qualifications to gain access to substations to carry out site surveys and produce reports.

  • National Grid Persons  

  • BESC    

  • WI 1&2 and EN 1&2, providing independent access to Scottish Power Energy Network Substations

Provision of System Test Documentation

We have extensive experience in providing detailed structured test documentation. We can prepare configurations, paper works, compile suitable test sequences, test procedures and documents to fully functional test any protection and control scenario.

Principal Designer Role

TES have qualified Principal Designers who can ensure projects are planned safely and in accordance with the Construction Design Management Regulations. Through our engagement we will strengthen design risk management and simplify Health and Safety in the pre-construction phase of the project.

CAD Engineering

Accurate design drawings and as-built drawings are key to the successful execution and completion of a transmission and distribution project. Let TES handle all of your CAD, drawing management, construction box, as-built and Operation & Maintenance manuals while your engineering teams focus their attention on detailed design activities. All information is stored on our secure server and backed up via a dedicated secure cloud connection.

We are experienced at working in accordance with TP135. Next day and weekend services are available for projects that need CAD work done urgently.
