AI Customer ServiceLeak current detection should be able to detect the total (including the DC and AC parts) effective value current, continuous residual current. If the continuous residual
AI Customer ServiceStandard and detection of leakage current According to the 7.10.2 regulation of NB32004-2013 standard, in any case where the solar inverter is connected to the AC grid and the AC breaker is turned off, the inverter should provide leak current detection.
Leakage current of the photovoltaic system, which is also known as the square matrix residual current, is essentially a kind of common mode current. The cause is that there is parasitic capacitance between the photovoltaic system and the earth.
While solar panels can protect your roofs, if you install the solar panels when the roofs are in bad shape, you would end up in more trouble. While the panels won’t protect the roof from the leak, it would be tough for you to revamp your roof after installing the solar panels. How to identify and fix the solar water leaks on the roof?
And it has an extremely high precision requirement, a special current sensor is required. The photovoltaic standard stipulates that for the detection of photovoltaic leakage current, Type B, that is, a current sensor capable of measuring both AC and DC leakage currents, must be used.
The result is PV leakage currents can indeed trip an RCD though inverters are supposed to check for and fault if such leakage exists though this feature can be disabled. Get the company back with a different technician or if that fails have it independently inspected.
Hazard of leakage current If the leakage current in the photovoltaic system, including the DC part and the AC part, is connected to the grid, it can cause problems such as grid-connected current distortion and electromagnetic interference, so as to affect the operation of the equipment in the grid.
