1. Non contact voltage sensor
ITRI developed an unique voltage sensor that can sense the electric field flux generated by the wire simply by measuring the induced current. By integration with data from current transformer, the real power consumption can be calculated. 
2. kW accuracy enhanced algorithm
The calibration algorithm by ITRI is applied to reduce the interference and noise introduced by the multiple-wire configuration. The accuracy of each individual sensor is improved through a system level configurational calibration after the whole system is setup in the switch panel.

Power Tab has been introduced in Famous telecommunications company and at one of the largest plastic manufacturer. There is no need for extra room in the installation, nor is it required to break the power during installation when circumstances prohibit power breakage.

This patented Power Tab technology has many advantages, including low-cost, no need to turn power-off while installation, easy wiring, and kW measurement. It provides a perfect solution for industries that need detailed energy disclosure. Besides, Power Tab technology can be integrated with various EMS system, such as KepServerEx, ITRI iAuto EMS and ITRI micro EMS for rapid energy disclosure and energy saving control.
