Product Description

Offered in 12”, 24” and 36” lengths, the Patrol Flex is the most accurate Rogowski Coil in submetering. Rogowski Coils offer significant installation advantages over split-core CT’s because of their light weight, wide current range (10-4000+ Amps), mechanical flexibility for mounting in tight quarters and easy placement around cable bundles or large busbars. The Patrol Flex leads can be extended up to 100’ without degrading the accuracy of the unit.

0.5% Revenue Grade Accuracy - Setra partnered with Fluke to deliver the Patrol Flex CT; the highest performance Rogowski coil in submetering. The Patrol Flex Rogowski Coil is calibrated to better than 0.5% accuracy for use in revenue grade (tenant billing) applications.

Save Money on Installation - Installers can save significant time and labor using the Patrol Flex due to its flexibility and ease of surrounding conductors or all sizes. Selecting a Rogowski Coil instead of a conventional split-core CT can save the installer over two hours per meter point in a challenging installation, which could be the difference between making and losing money on a job.

Wide Current Range = Reduced Shipping Costs - A typical 100A CT weighs 2 lbs, however as the current range expands to 3,000A the average weight can increase from 2lbs to 20 lbs. Considering three CT’s are required to monitor a 3-phase motor, certain applications could require up to 65lbs of shipping weight per meter point; a serious waste of shipping dollars. The Patrol Flex Rogowski Coil has a current range of 5-4,000A and up, yet weighs less than 1/2 lb, drastically reducing freight costs.

Best in Class Linearity - Conventional CT’s are wound over a magnetic iron core, which makes them more susceptible to saturation leading to linearity error. Engineers and contractors must adjust the phase shift of the meter to compensate in order to achieve an accurate reading. Rogowski Coils are wound over a non-magnetic core, giving them perfect linearity and improved accuracy over wide current ranges.
