AI Customer ServiceAs mentioned, detection of a DC ground fault is difficult, particularly in large PV systems. This is because DC ground faults are often less than the minimum sensitivity of the GFP device.
AI Customer ServiceModules with defective module isolation, unshielded wires, defective power optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth).
AI Customer ServiceThe problem here is that, the DC leakage current in the cables flows through its insulating material through ground, and this is often known as DC leakage. The faults in the
AI Customer ServiceThe first is to effectively release the capacitive leakage current of the system to avoid excessive accumulation; the second is to ensure the safety of the system. If the grounding is sufficient
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 current exceeds the following limits, the inverter should be disconnected and send a fault signal within 0.3s:
Standard 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.
In photovoltaic systems with a transformer-less inverter, the DC is isolated from ground. Modules with defective module isolation, unshielded wires, defective Power Optimizers, or an inverter internal fault can cause DC current leakage to ground (PE - protective earth). Such a fault is also called an isolation fault. system. WARNING!
There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.
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.
