TK3310 miniature three-phase standard energy meter (intermittent type)

TK3310 Miniature Three Phase Standard Energy Meter (Intermodal Type) ◉ TK3310 is a miniature three-phase indirect connection standard energy meter, with two specifications to choose from: 0.01 level/0.02 level. ◉ Suitable for on-site detection of the basic errors, power stability, distortion, etc. of the automatic calibration system for three-phase electric energy meters connected through transformers, which can comprehensively improve the automation and detection level of the measuring equipment. ◉ Powered by a built-in battery, it can reduce the impact of traditional PT power supply methods on accuracy testing. ◉ With a wide range of current measurement capability from 1 mA to 6 A, current measurement does not require a single range change and has high reliability. ◉ The external dimensions should be consistent with the existing national electricity meter to achieve full automation testing.
