Insulation monitoring device for unearthed photovoltaic systems up to AC 1000V* and DC 1500 V Product description The device is used for insulation of large photovoltaic systems up to AC 1000 V*/DC 1500 V designed as IT systems. The measurement method specially developed for slow voltage fluctuations (MPP tracking) monitors the insulation resistance even in systems equipped with large solar generator panels where extremely high system leakage capacitances against earth exist due to interference suppression methods. Adaptation to system-related high leakage capacitances also occurs...

Response time for insulation measurement isoPV1685... Response times insulation resistance measurement 1000 In the case of a leakage capacitance of 2000 µF, the measuring range for the insulation resistance is limited to 50 kΩ. The measurable leakage capacitance depends on the insulation resistance Minimum limiting condition for determining the value of the capacitance The determination of the leakage capacitance depends on the size of the insulation resistance. Example: In the case of an insulation resistance of 50 kΩ , the minimum measurable leakage capacitance is 35 μF. In the case of an...
