GreyMatters specialise in Electrical Earthing Grounding Services. Therefore, we take the earthing Risk off the table for your high-value critical assets. – Which means, in the process demystify any complexity into an easy-to-understand earthing system design, plan or strategy for you.
Hence, GreyMatters advice, designs and support will make your life a little easier. In so much, when you have a High Voltage Power System that needs HV electrical earthing grounding design. So, we do the leg-work to get your project compliant with the latest IEC / IEEE standards. So, you don’t have to worry.
As a matter of fact, compliance comes built-in, so your high voltage earthing system design is neither over, nor, under-engineered – it’s a correctly optimised so that every penny you invest, is a penny
“So, Say goodbye to open check-book installations!”
