The WHT is a two processor based power monitoring device that monitors and records numerous power system parameters. It continuously measures voltage and current to calculate and display over 57 values. 120 to 600V can be monitored without the need of potential transformers. 601 to 32000 V can be monitored with the use of potential transformers. All scaling calculations are handled by the meter. The WHT comes standard in a NEMA 4 rated enclosure ready to be mounted. A data port is provided on the front interface for easy setup and trend retrieval via desktop software.
