Current Sensor, Transformer & Monitoring Systems

Current monitoring covers the three devices that turn a live conductor into a number: a current transformer steps heavy current down to a safe proportional signal, a current sensor turns it into a controller input, and a power monitor records what the circuit actually consumed. Energy and protection teams fit them when load has to be watched rather than assumed, when a saturated transformer has been giving a false reading, or when new metering has to be added to an existing bus.

 

As an authorized electrical distributor for multiple manufacturers, we stock current transformers, current sensors and power monitoring devices from ABB and more across competing lines, so you can take the sensing and the recording from one order, compare circuit types and communications across brands, and measure a feeder rather than estimate it. Same-day shipping on in-stock items ordered before 2pm local time.
