Current Transformers from Standex Electronics Allow “Time of Use” Monitoring and “Smart Meter” Monitoring for Electricity Usage

Cincinnati, OH – May 21, 2012 – Standex Electronics introduces their CT current transformers which allow “time of use” and “smart meter” monitoring of electricity usage. Faced with the expensive option of adding electrical capacity, these methodologies allow utilities to monitor the time of use and invoice those customers that are driving the need for increased capacity with higher rates – thereby altering demand. Standex CT transformers are applied on circuits with current that is too high for direct monitoring. Current in the monitored circuit produces a reduced but proportional current in the Standex Current Transformer which is then monitored by measuring instrumentation. This serves to isolate the measuring instrumentation from the monitored circuit. CT transformers have minimal size/space requirements, making them ideal for new construction or retrofits of apartment buildings, condominiums and other multi-tenant structures.

Highly accurate, these proven 200-5A transformers are available with accuracies of 0.30% as standard. They include a 10-foot lead length of #16AWG wire, which is believed to be the longest in the industry. Standex CT current transformers, which also have UL approval for the US and Canada, are ideal for use in electricity sub-metering in condominiums and apartments – as the sensing component within the metering system. In addition to sub-metering, time of use monitoring is also facilitated by the CT. Models are available for use with socket meters or closet meters. They are designed for primary currents of 200 amps, and for secondary currents of 5A.

“These highly accurate transformers are ideal for smart metering applications – as evidenced by their approval from Measurement Canada for this application” said Christian Rogiers, Director of Global Marketing for Standex Electronics. “Their small size and long lead length allow their easy installation into new buildings as well as retrofits of existing multi-tenant structures.”
