What is the Problem?
As the UK aims to achieve net zero by 2050, low carbon technology (LCT) like EV chargers and heat pumps are being installed at a significant rate (around 3.5m new connections each year). This rapid growth is causing more customer complaints about voltage levels falling outside of the regulatory limit of 230 V +10%/-6%.
Currently, UK Power Networks (UKPN) use a qualified inspector to install a voltage recorder in the customer’s home for two weeks. The device is then collected and the data analysed; a slow and resource-heavy process.
Preferred output
UKPN want a voltage monitoring device that can be installed for the duration of an inspector’s visit to a property experiencing voltage fluctuations. The voltage trend needs to be transmitted to the inspector’s mobile phone or laptop.
The key requirements for the voltage monitoring device are:
- To be safe to be left plugged into a standard 13A socket unattended while the inspector carries out his checks
- To collect RMS voltage data for the duration of the inspectors visit allowing for a voltage profile to be displayed
- To have the ability to connect to a pre-existing portal such as iHost and begin transmitting voltage data immediately upon connection
- To use mobile 4G or similar communication technology for real-time data transmission
- To be stored in a protective case
- That it is priced similarly to a multi meter, ie less than £100.
