1st, electricity stealing is prevented.Because in general stealing process occurs in low-pressure side, i.e., in secondary line, high-pressure side is moved
Trick can risk sizable risk, jeopardize its personal safety.
2nd, sample transformer and metering module is integrated, avoid the secondary voltage drop phenomenon occurred in secondary measurement mode, count
Accuracy of measurement is high.
3rd, sample transformer and metering module is integrated, the wiring for avoiding occurring in secondary measurement mode is complicated, safeguards not
The problems such as facilitating, reduce job costs, reduce failure odds.
Even so, but at present high-voltage electric energy meter on the market there is a problem in that：
1st, according to national measurement method relevant regulations, the measurement instrument to being related to trade settlement, it is necessary to which timing carries out cycle inspection
It is fixed, it is ensured that its function is normal, precision is in acceptability limit.If identified every year high-voltage electric energy meter, must just have a power failure into
OK, for user, frequently have a power failure, it is difficult to receive.
2nd, high-voltage electric energy meter if there is technical failure or needs to carry out technology upgrading, it is also necessary to which to have a power failure can be real
Apply, it is very inconvenient.
Problem above, especially first point, it have impact on the effective popularization and application of high-voltage electric energy meter.It is so most of at present
Or high pressure side joint voltage/current transformer is used, high voltage, high current are changed into low-voltage, low current, then connect secondary meter
The mode that amount instrument is measured.As described above, this mode still occurs that stealing, secondary voltage drop influence measuring accuracy etc.
Phenomenon.
