12 Apr PQM-701, PQM-701Z, PQM-701Zr, PQM-702: Why is the value of asymmetry 327,67%?
The value is shown unbalance because of the faulty connection of analyzer to the network – switch off two voltage test leads.
Unbalance on the level of 327% is impossible in reality (maximum real value of unbalance can be 100% in theory). This is also visible in the value of opposite component of U2, which usually should be within single volts.
For correctly connected system, value of U1 should be about the nominal voltage.
