Arc furnace current sensors installed at specialist company in Gauteng
12 March 2003
News
Cape Town company SURE Engineering recently designed and manufactured a set of SURETECH high current sensors for Johannesburg-based electric furnace specialist company, ELFU Engineering and its client, which the company says is happy with the installed performance of the sensors.
Rogowski coil technology was used, which has been field-proven in various applications over the past two years by SURE Engineering. Rogowski technology uses 'air cored' current sensing, which has been known for the past century. The technology has not been exploited much due to the tricky signal processing that is needed, says the company. SURE Engineering believes that the potential of this technology is enormous.
The three sense coils were each mounted around its bus-bar phase of the electric supply to the arc furnace. Each phase carries a maximum of 8000 A a.c. Each sensor has a screened cable carrying the low-level signal to a SURETECH transducer, which processes the signals generated. The signals are complex in waveform as the arc furnace is continuously changing its current. According to SURE Engineering, the wide bandwidth requirements need special care, especially on the low frequency side. The company now has Rogowski coil technology well under its belt. In fact, it even offers these current coils with integrated voltage sensors too.
SURE Engineering will be exhibiting this Rogowski technology, and other innovative and unique SURETECH current and voltage sensing technology at the CIRED exhibition in Barcelona later this year.
