Three Phase Three Wire/Four Wire Class 0.1S Meter--MDVH3016 manufacturer
HHigh-precision measurement: Achieve 0.1S-level accuracy, compared with ordinary electric meters, the error is smaller when measuring active energy in three-phase three-wire or three-phase four-wire circuits.
Multi-function measurement and strong compatibility: In addition to basic energy measurement, it can also perform reactive/apparent energy measurement, power quality measurement, etc.
FAQ
1. What is the accuracy of a 0.1S-class meter?
0.1S-class: means that the meter has a measurement error of no more than ±0.1% within the range of 1%~120% of the rated current, and is a high-precision meter.
2. In which scenarios do you need to use a 0.1S-class meter?
Such as the power delivery between power plants and power grids, and the power transfer measurement between large enterprises.
3. How to choose a three-phase three-wire or four-wire 0.1S-class meter?
If the power supply system is a "three-phase three-wire system", select a three-phase three-wire meter; if it is a "three-phase four-wire system, select a three-phase four-wire meter.
