Power quality specialist REO UK has launched a new range of current transformers designed to ensure high power efficiency and quality by offering highly accurate linear current sensing and electricity metering. These transformers come in a selection of power ranges to suit industry sectors including automation, railway engineering and renewable energy.
As electrical control systems get faster, they become responsible for higher currents and frequencies. This is driving demand for current transformers that can provide precise measurement even at these increased levels of operation and regardless of current type.
To meet this demand, REO’s range of current transformers are able to accurately measure currents up to 3000A and frequencies up to 150kHz while providing superior linearity and overcurrent protection. Each series of transformers is designed to deliver reliable power quality catering to a specific industrial sector; for example, the series IE is suitable for use under high currents in the rail sector.
Depending on the application in which it is being used, there are different electrical expectations for each current transformer. As an increasing number of electronic devices begin to operate on higher working frequencies, applications that involve such devices will require a current transformer with an extended frequency range, such as REO’s IN series of instrument transformers.
“As they are used in a wide range of applications it is essential that current transformers offer versatility,” explained Steve Hughes, managing director of REO UK. “Both in terms of technical and mechanical properties, a current transformer must be a perfect fit for a circuit before it can benefit the application.
“Housing and termination casing can be just as important to an application as the electrical characteristics of the transformer itself. Finding a product with the ideal frequency range isn't beneficial if it lacks suitable connections and fittings to be successfully implemented into a specific system.”
