PowerLogic™ Current Sensors Technical Datasheet
Solid Core, Split Core types, and Rogowski Coil
Schneider Electric's Current Transformers (CTs) offer secondary voltage AC or secondary amperage proportional to the primary (sensed) current. These CTs are designed for use with power meters, data loggers, chart recorders, and other instruments, providing a cost-effective means to convert electrical service amperages to a voltage or current compatible with monitoring equipment.
The Low Voltage CTs are available in Split Core and Solid Core models, with 0.333 Vac output versions. Current Output CTs are available in Split Core models with 5 A output versions.
Schneider Electric provides four proven models of PowerLogic™ Rogowski flexible core current transducers, ranging from 300 to 900 mm in length and operating within a current range of 50 to 5000 A.

CT Principle
When the primary circuit of a Current Transformer is energized, the Current Transformer presents a very low impedance to the secondary circuit, resulting in a low secondary voltage across the burden.
Diagram Description: A schematic shows a primary conductor (Ph) connected to P1 and P2. The secondary circuit has connections S1 (White X1) and S2 (Black X2) leading to a Low Voltage Output, connected via a resistor (R) to a load. The diagram illustrates the basic electrical principle of a current transformer.
Solid Core LVCTs
CT Selection - Conductor Rating Aspects
- The choice depends on the conductor size and the maximum current of the primary circuit.
- Primary current can be measured through CT with let-through primary.

CT Principle
When the primary circuit of a Current Transformer is energized, the CTs present a very low impedance to the secondary circuit, resulting in a low secondary voltage across the burden.
Diagram Description: A schematic shows a primary conductor (Ph) connected to P1 and P2. The secondary circuit has connections S1 (White X1) and S2 (Black X2) leading to a Low Voltage Output, connected via a resistor (R) to a load. The diagram illustrates the basic electrical principle of a current transformer.
When the primary circuit is energized, the measurement equipment acts as a short circuit which keeps the secondary voltage very low. This voltage increases significantly if the short circuit is removed.
