Engineering Consultancy

In addition to a range of design and surveying work, Line Design Technology Limited also offers engineering consultancy services, providing independent expertise to those working within the electrical industry.

With a skilled and knowledgeable consultancy team, LDT can answer questions with regards to specific developments (acting as an expert witness when required) and aid in determining the best route, specifications, and materials for an overhead power line project.

The engineering consultancy offered by LDT gives clients access to a range of practical and innovative solutions for the design, construction and ongoing maintenance of overhead power lines.

Below are details of some of the projects we've worked on over the years

Voltage Regulator Structure Design

Voltage Regulator Structure - LDT

LDT’s services were engaged by Scottish Power Energy Networks to undertake a design study to facilitate the mounting of voltage regulators on a wood pole structure.

Due to the increased amount of micro generation on the electricity network in rural areas, there has been a need to regulate the voltage of the network on a more local level.

SPEN approached us to assist with installing three Cooper Power Systems Voltage regulator units on a wood pole structure.

We produced several design concepts based around the OHL-09-03-099 design specification. The main project goals were to utilise as much standard specification materials as possible, to avoid the need for costly bespoke fabrication.

The final design was a two-pole structure that enabled a minimal footprint, which was conducive to landowner negotiations.

The only non-standard steelwork was the VR platform which consisted of a C channel beam, braced by tie struts.

The design was so successful that Northern Power Grid engaged LDT to produce a similar structure for their network.


Rhyl Grid - Downlead Reconfiguration

Rhyl Grid Substation - LDT

The T2 transformer at Rhyl Grid is in need of replacement and LDT were engaged to come up with a solution to facilitate a jumper configuration to allow for the decommissioning of the existing transformer.

As Rhyl Grid is served by a single circuit 132kV connection the T1 transformer needs to remain energised.

The existing jumper arrangement didn’t allow for the T1 circuit to be disconnected without affecting the T2 circuit. LDT conducted a 3D survey of the terminal tower and existing jumpers.

The existing arrangements were then modelled in CAD to produce a digital representation of the pylon. This enabled LDT’s designers to virtually reconfigure the jumpers to see if a workable solution could be found.

By modelling the tower in 3D, clearances could be checked to ensure safety distances are maintained. A detailed stage by stage works schedule could then be developed to facilitate the transformer outage.
