CAS DataLoggers has introduced a 3-phase submetering kit for reducing energy costs, consumption, and carbon emissions. The Electrocorder EC-7VAR 3-phase voltage, current and power factor data logger kit helps save energy by providing an onsite view of power consumption in kWh. It also identifies power spikes and voltage supply faults.

For motors, lighting and other similar electrical equipment, the average voltage supply is often more than the standard operating voltage. This leads to increase in current and electricity consumption. The EC-7VAR kit monitors and saves on consumption costs. It monitors current and voltage variations as well as power and energy usage. The cause of low voltage – whether it is due to low voltage supply or due to high demand of current – can be determined. Electrocorder provides the EC-7VAR in four models that can record at amps ranging from 90 kVA - 690 kVA per phase to 270 kVA - 2 MVA in total. These models include four voltage leads, a USB lead, three Rogowski Coils, and free software.
The EC-7VAR kit utilizes a constant data sampling technique that takes samples of each cycle multiple times. It can record continuously for a period of 300 days. The voltage for plotting the energy and power can be defined by the user through the software provided by Electrosoft. The recorded data can be uploaded to PCs through a USB. The power factor for a current channel and a voltage channel are recorded and this data is used to calculate the reactive, apparent and real power for the three phases. This measurement helps determine the necessity of any power factor correction.
