With expertise in board level electronics and also in programming control software including Labview, Visual Basic, etc, Earthed Electrical are perfectly placed to advise on process control machinery.
One of our recent projects has been developing a test bench to quality check inverter drives prior to distribution. The benches will run 115 separate tests from load to calibration and report statistics centrally via a custom program. This work has resulted in fewer returns, better customer experience and increased performance from suppliers saving the business tens of thousands of pounds each year.
We have also created demo cases for sales people to show electrical equipment to potential customers. Simply plug in and give a meaningful demonstration of how the equipment works.

New test machines power Invertek’s ambition for world-leading quality
Leading drives and power control company Invertek has installed new automated testing machines, developed for it by Earthed Electrical Services, which are delivering major process and quality improvements.
Invertek Operations Director Charles Haspel said the new testing machines are a key element of the company’s “Customer Perfect” strategy which aims to establish Invertek as a world leader in manufacturing quality.
He added: “We already have a strong reputation for quality, but we are seeking an order of magnitude in driving down product failures. This new automated testing regime is a key part of the jigsaw in achieving.”
Mr Haspel said the testing machines, developed in partnership with Invertek by Brian Walker, of Telford-based Earthed Electrical Services, represents the biggest advance in power control testing he has seen in 20 years.
He said: “I wanted a testing approach that delivers whole system improvements and that is what Earthed Electrical Services has achieved. It is hugely impressive and hugely significant for us as a company.
“The testing machines provide us with full automation of product configuration and an indepth functionality test of power electronic products. This has delivered measurably greater certainty for our quality systems.
“It has also allowed us to review and plan our production systems with greater confidence which will help drive our plans for increasing output while constantly improving the reliability of our products. It has also improved operator satisfaction.”
Over an intensive 36 month development period, Earthed Electrical Services has built eleven testing machines at Invertek’s factory in Welshpool, Powys.
Brian Walker, Director of Earthed Electrical Services, said: “We take a whole system approach to providing solutions like this. Our aim from the beginning was to make the machines as flexible and futureproof as possible.
“They will test any product and any variant of the product. With the software we’ve developed, new product tests can be set up in days. We have also set out to make the equipment simple and quick to use so a technician can operate it rather than an engineer.
“A full test run can take as little as five minutes and because it is fully automated, repeatability is guaranteed. The programme also allows unusual faults to be flagged up and tested for before the item leaves the factory.”
Mr Haspel said the testing machines will support Invertek’s already strong research and development programme. They will be used to develop and test key specifications for new products, such as energy saving performance or specific functions and power outputs, which it can then tell customers with 100% assurance will be delivered.
He said: “The database driven control configuration the machines deliver will form a key part of our strong competitive advantage. They are giving us completely new ideas about what we can achieve. That is very exciting for us.”
Invertek is fast becoming a major player in the design, manufacture and marketing of electronic variable speed drives for controlling electric motors.
The company employs 110 people in Welshpool and 16 more in China. It also has joint ventures in the CzechRepublic, Spain and Singapore.
Products include the world-leading OptidriveTM CP2 which provides world-leading performance for standard induction motors and permanent magnetic motors.
