Easywire CTs
By using the Rayleigh Instruments easywire® system of Current Transformers and Energy Meters, installation labour savings of around 90% are achieved when compared to traditional wiring methods.
The easywire® system is also safer than using traditional current transformers because easywire® current transformers incorporate the resistive shunts usually located within the power meter. This means that the secondaries are always loaded, therefore eliminating the possibility of dangerously high voltages developing during open circuit conditions.
All our easywire® current transformers have been designed with hole centres and apertures to fit most standard industrial circuit breakers.
