Description

Rogowski loops are a new generation of flexible current transformers that allow users to easily pass the product around the cable or bar, even in confined spaces.

Rogowski loops are particularly suitable for installations with limited accessibility or when switching off the system is not possible.Because of their design, they can be installed while the installation is live.

Our wide range of Rogowski loops allows measurements from 60 to 4800 A.

Equipped with a 333-mV converter, the Rogowski loop offers an accuracy class of 1% from 10 to 120% of rated intensity.

Flexibility and ease of use

Unlike traditional current transformers, the Rogowski loop is flexible and easily adapts to different busbar or cable diameters. It is lightweight and compact, making it easy to install and use in confined spaces.

Flexibility

The Rogowski loop offers a wide measuring range from 60 to 4800 A depending on the model, ideal for a variety of industrial and tertiary applications.

=

Precision

The Rogowski loop offers exceptional accuracy, 1%, from 10 to 120% of the load. Thanks to its unique design and features, it gives you reliable, accurate measurements.

3
=

Zero outage

The Rogowski loop’s 333 mV converter allows the equipment to be opened and closed while live, and without any risk to the user. This 333-mV secondary also allows a distance of several metres between the loop and the energy meter without any loss of measurement accuracy (unlike a 5 A secondary).

Easy wiring of existing installations

The BACS (Building Automation and Control System) requires all commercial buildings to be fitted with a BMS if they have a heating or air-conditioning system of more than 70 kW.

Our range of open CT or Rogowski loop meters makes it easy to add metering points to your electrical installation with minimum downtime. There’s no need to de-cable the existing installation, just wrap the cable around the CT or loop.

What’s more, our network expert can offer you a support service for uploading information to a web page.
