Looking at using 3 of these voltage transformers for my 3 phase install in Australia, reasonably priced at AU$12.50 from Jaycar. Will be installing them into an enclosure & hard wiring to the 3 phases and neutral.
1: They are multi voltage tapped, should I use the full 15v tapping?
Will phase shifting be lower if using the full secondary coil rather the the intermediate taps?
Should be low phase shift as they weigh in at 665g ( 23 Oz). Apparently the bigger the better.
2: I will be using HWCT-004’s (known phase shift) CT’s, should I use the browser url:
iotawatt.local/command?vtphase=3 to obtain a measure of the relative phase difference between CT and VT. Or can it be done between the 3 VT’s?
