STPMS2 Description
The STPMS2 also called “smart sensor” device, is an ASSP designed for effective measurement in power line systems utilizing the Rogowski coil, current transformer and Hall or shunt sensors. This device is designed as a building block for single-phase or multi-phase energy meters along with the STPMC1 device, a digital signal processor designed for energy measurement. This device can be used in medium and high...
