What Is A Trivector Meter? Where Is It Used?
A three-vector meter is a type of energy meter that can measure active, reactive, and apparent power as well as the energy of the electrical energy source.
It can also measure peak demand, power factor, supply voltage, and current.
Tractor meters are used for commercial and industrial purposes where accurate billing and monitoring of energy consumption are required.
Tractor meters are typically connected to current and potential transformers that provide input signals to the meter. The instrument then processes the signals using a microcontroller and displays the results on an LCD screen or transmits them to a remote device¹²³.
Tractor meters are widely used in substations and power lines, where they can measure the current flowing through the lines and help optimize power distribution. They are also used by large electricity consumers such as factories, offices, shopping malls, etc. who have to pay for the energy they use at different rates and time intervals²⁴.
Three-vector meters can help these consumers reduce their electricity bills by shifting the load to off-peak times or improving power factor. Tractor meters can also help detect power outages or anomalies such as voltage fluctuations, harmonics, or energy theft¹⁴.
