CTV Current Sensor with voltage outputs, compatible with most transducers, based on "rope type" Flexible split core Rogowski coil transformer

The CTV current sensors are the world's first flexible 'clip-around' current probe with 0.333V and optional 5A output, allowing compatibility to existing 0.333V metering circuits and 5A metering. Unlike conventional CTs, there are no open circuit hazards - ideal for retrospective metering projects and installations in confined spaces where installation of conventional iron core CTs is not possible. The CTV flexible current sensor also simplifies installation and eliminates the need for expensive LV/HV plant shutdown.

The CTV sensors convert ac current to an isolated 0-0.333V, 0-5V or 0-10V with available ranges from 100A to 10,000A. Because the current sensors are flexible split core, installation is possible without shutting down the LV electrical supply, avoiding expensive down-time costs. Typical applications are retrospective energy monitoring in factories, offices buildings, process control data logging systems, where power, energy and current monitoring is important. Typical applications are factories, offices buildings, ac/dc VFD drives, welding, power conversion and power distribution. For all CTV sensor models, an A2LA NIST/NPL (UKAS) traceable calibration certificate and certificate of conformance is supplied. All CTV sensors use UL94V0 or CSA approved materials. The CTV flexible current sensors are suited to permanent or semi permanent installation. The coil sensor is durable, lightweight, flexible and will easily clip-around a power cable. The optional 5A output (CTA) connects direct to installed 1A or 5A metering, rotary metering or current transducers.
