Measuring Each Phase of a 3-Phase Supply Independently
Challenge:
Our client had been requested to install metering on a 3-phase supply which had been split to three independent office units. Each office had been supplied with their own phase, and the building owner wanted to monitor consumption so they could bill each office for their share. It was advised that the end user was not technical, so they had requested a fool proof method for reading.
Solution:
S P Wales supplied a pre-wired enclosure incorporating three single phase meters, one for each phase. While many 3-phase meters are able to show consumption per phase, by installing three independent meters, it ensured an easy process for reading the meters and assigning consumption to the correct office. The pre-wired enclosure was supplied complete with split core CT’s to easily open and clip round the supplies to be measured. The meters were pre-programmed and the enclosure fitted with the appropriate fused terminals for the voltage references, all with a view to ensuring the installer had a simple job when fitting on site.
