Single Phase – A single phase electric meter is a two-wire AC and is typically used on services that use lower consumptions. It must have a single phase supply feeding into it to be installed. The maximum voltage used for a single phase is 230V. Typically a single phase meter will have one 100amp fuse.

Three Phase – A three phase electric meter has 3 individual electric services feeding into it. This is used on supplies that have a higher consumption than those of single phases. Again, to have the meter installed, it must have a three phase supply feeding into it. The maximum voltage used for a three phase is 415V. A three phase will typically have three 100amp fuses.

Half Hourly – Half Hourly meters are designed specifically for business energy users. The technology uses Automated Meter Reading (AMR) to capture consumption data every 30 minutes. It helps businesses to see a deeper understanding of usage patterns and peak consumption times. They are a legal requirement for businesses that consume 100kw or more during a half hour period. If you have a maximum half hourly demand of 70kw you can also opt for a half hourly meter.

CT – Current Transformer meters are installed on any connections with a load greater than 100 Amps. They measure a fraction of the amps passing through the connection and multiplier is applied to reflect the actual amps. All CT Meter will have a CT Ratio which will be in a format of X / X.
