SUSTAINABILITY
themselves or neighbouring equipment. Protection against transient voltage events should also form part of the design process. Voltage spikes caused by switching operations or lightning activity can damage sensitive electronics and reduce the operational life of charging equipment. Installing surge protection devices (SPDs), such as SineTamer devices, provides an effective first line of defence by diverting damaging transient energy away from critical assets.
A coordinated approach Surge protection is only one part of the solution. Where harmonic distortion is expected to be significant, additional mitigation may be required. Active harmonic filters continuously monitor the electrical supply and inject compensating currents to reduce distortion as loading conditions change, making them particularly suited to charging hubs where demand fluctuates throughout the day. The Comsys ADF range has a well-established impedance control software licence to help manage site resonances with ease and avoid costly failures caused when a site’s electrical system is mostly capacitive due to the EV chargers.
As EV adoption grows, attention will naturally focus on increasing the number of charging points available across the country. However, reliability is just as important as availability.
By considering metering and monitoring, surge protection and harmonic / supra-
harmonic mitigation and making power quality part of the design process from the outset, operators can reduce downtime and build charging networks that are ready to support the UK’s transition to electric mobility.
