A New Approach to Circuit Breaker Design Using Silicon Carbide Switches - Nov 21
Mechanical circuit breakers can be low cost with minimal losses, but they operate slowly and wear out. Solid state versions overcome the problems and are becoming increasing viable as replacements at...

Current transducer measures in three phases

Described as a convenient way to measure current in three phases, the RCTrms three-phase current transducer is from Power Electronic Measurements (PEM).

It features a thin, clip-around, flexible sensor coil and provides true RMS measurement with 4 to 20mA or 0 to 5V output. The compact, DIN-rail or panel mountable transducer connects to three Rogowski coils to capture measurements from three current phases simultaneously. With 18 current ratings options from 100 to 50,000 A, and a choice of 300, 500, 700mm or custom coil lengths, it can be used in a variety of SCADA systems, PLCs, data loggers, protection equipment or motor controllers.

The clip-around coil design allows fast and easy positioning for results without needing to be centralised around the conductor. An isolated BNC-BNC cable-split option is also available, to ease installation such as when threading through existing conduit.
