Connection alternatives
In the electric grid there are multiple configurations of instrument transformers (PT= Potential
Transformer, CT= Current Transformer). The UP-2210 meters support all standard 1-phase and 3-
phase connections. The meter is configured using PQ Online, where all the common connections
methods with their respective wiring diagrams available and a graphical explanation. Here it is also
possible to set the transformer ratios as constants.
