the manufacturer doesnt comment on the problem and says it could be cause by an unbalance between the poles of the correction capacitors..yet they fail to give a convincing explanation
the tranformer in use is called the H61mostly 50 KVA rating
delta to wye
22kv-400v
the meter expects a wye connection thus the neutral connection in the meter
thank you guys for ur suggestions
i have been working on the problem and checked all the sequences from the secon dary of the distribution transformer to no avail :(
The electronic meter is connected to 3 CT's one per phase the voltages are taken from the secondary of the transformer (240V L-N) and connected to the meter with...
Actually a the meters were tested and calibrated today ..doesnt change anything ..still shows exprot or active energy
THis phenom happens only with customers equipped with capacitor banks
i know he reqding on the meter is related to the capacitors banks just cannot find a logical explanation...
there are altaris(french) meters
and they only display the magnitudes or the phase votages and currents...they also show a warning when the phase sequences are not respected.. so my guess is that it s not a sequence problem ..unfortunately :(
that was my first guess also but doesnt seem to be a...
we have been experiencing some weird issues concerning exported energy into the distribution grid ..the meters show readings for exported active energy at customers having capcitors installed for power factor correction
when the capacitors are disconnected the meters show 0 KW exported
