What is CTS?
As our journey and ambitions to reach #netzero continue, so does the need for improvements to our #energy distribution networks. Coupled with the increasing demand for new transmission infrastructure, we should be full steam ahead with progress… but we aren’t.
Communities worldwide are seeking ways to integrate #renewableenergy into their day-to-day lives. Whilst this trend is growing, the NIMBY effect (not in my back yard) cannot be understated. The construction of overhead lines is often met with resistance by local communities, thus forcing DNOs (distribution network operators) and renewable energy developers to use other means – such as underground cables – more frequently and over much greater distances.
Fundamentally, this would not be an issue, but the current performance capabilities of standard cables are inefficient.
In a study for a DNO, a prototype capacitive transfer system (#CTS) cable was designed and manufactured by Enertechnos . The CTS cable offers lower cost, weight, and #carbon embodiment in installation, a more even current distribution, reduced voltage drops for the same load, and provides reactive power compensation. All of this leads to reduced CAPEX (capital expenditure) and OPEX (operating expenditure) over time compared to a traditional cable.
While also benefitting the planet, the reduced voltage drop also helps consumers. This is because there is much less ‘wasted energy’, thus minimising the cost for end-users.

So, how does all this work? The CTS AC cable introduces distributed series capacitance. Inside the cable core, input and output layers are separated by a dielectric layer which introduces a series capacitance effect.
If all of this sounds technical, it’s because it is! But that certainly doesn’t mean we will stop creating, testing, and delivering high-impact solutions.
In our planet’s quest to reach net zero, being able to reduce power losses is a significant step in the right direction.
