Application:

Incorporated into products used for electric power measurement, electric power quality monitoring, Supervisory Control and Data Acquisition (SCADA). The Rogowski Coil current sensor is ideal for current measurement applications that require a wide AC current input range and a wide frequency response range. Suitable for relatively small primary conductors, the mini-loop split-core design permits the installation of the sensor without disconnecting the primary conductor. These sensors offer exceptional accuracy in harsh environmental operating conditions.

Features:

• Split-core loop enables sensor installation while the primary conductor is “live”.
• Minimum sensitivity to primary conductor position within the sensor loop.
• Conforms with IP65 rating for outdoor environments.
