42 Technology announces a novel technology for robust, low cost polyphase metering

42 Technology’s expertise in metering and low cost electronics has led to the invention of a novel technology for robust and accurate polyphase metering with system costs estimated at up to 30% lower than currently available solutions.

This breakthrough approach uses a resistive sensing topology, which is already the preferred approach for single phase meters on account of its cost, performance and magnetic immunity. We have developed several working prototypes and are now actively looking for commercial partners to help bring the technology to market.

The resulting system is completely immune to strong DC magnetic fields and offers high isolation voltage up to 15 kV, whereas most alternative technologies fail at 12 kV or less.

It also offers additional performance and manufacturing benefits over existing metering topologies including: more accurate current measurement across a wide dynamic range from 100 mA to 100 A; higher frequency current measurement into the MHz region; and lower costs for product assembly and test.
