Description
The TIDA-01088 reference design implements power quality parameter measurement in a polyphase energy measurement system. Total harmonic distortion (THD), fundamental readings, and standard metrology parameters such as active and reactive energy and power are calculated. Phase to phase angles are also calculated to help prevent incorrect installation of the system. This design uses isolated shunt current sensors to maintain accuracy in harmonic analysis and also immunity from magnetic tamper attacks.
Features
- Class 0.5% Three-phase metrology with galvanically isolated shunt current sensors
- Isolation performance of up to 1-kV AC (working voltage) and 7 kV (Peak)
- Total Harmonic Distortion (THD) calculated for Voltage and Current
- Voltage Sag and Swell events logged with programmable threshold levels
- Phase to Phase angle measurement for determining phase sequence to help prevent incorrect installation of system
- Complete Energy Library with Fundamental Voltage and Current, Fundamental Active and Reactive power, Active and Reactive Energy, Root Mean Square(RMS) Current and Voltage, Power Factor, and Line Frequency
