About Current Transformers
Measure and monitor AC current with a current transformer. This type of transformer enables the safe and ongoing monitoring of high currents without having to tap the load circuit with a probe. Within these transformers, a secondary winding surrounds the primary load carrier and generates a proportional current that can be measured by an ammeter. That proportional current can also open an overload relay if the current exceeds a set threshold. Manufacturers include Square D, Simpson electric and others.
