Current Transformer

Current transformers step a high alternating current down to a small, safe, proportional current, so a meter or relay can measure a heavy feeder without being connected to its full load. Meter installs call for one when a feeder carries more current than an instrument can accept directly, when a CT has been found saturated or wrongly rated, or when new metering has to be added to an existing bus.

 

As an authorized electrical distributor for multiple manufacturers, we stock current transformers across competing lines, in a full range of ratios, window sizes and accuracy classes, so you can match the ratio and window the conductor needs, compare ratios and accuracy classes brand to brand, and meter a heavy feeder safely.
