TD5610 is a modular high-voltage wideband power standard meter. 

It consists of a V/V converter, an I/V converter and a three-phase wideband standard meter. Under various wiring methods such as three-phase Y/V, it can simultaneously measure multiple electrical parameters in the AC circuit, including: voltage, current, frequency, phase, harmonics, active power, reactive power, apparent power, power factor, active energy, reactive energy, etc. The measurement uncertainty has two specifications of class 0.05 and class 0.02.

The instrument is widely used, small in size, light in weight, and easy to carry and use on site.
