ISOMETER® isoPV con AGH-PV
- Insulation monitoring device for AC and DC IT systems
- Application photovoltaic systems up to AC 793 V/DC 1100 V
- Separately adjustable response values 200 Ω…100 kΩ
- Automatic adaptation to the system leakage capacitance up to 2000 μF
- Isometer disconnecting relay for the operation of several ISOMETER® in interconnected IT systems
The ISOMETER® of the isoPV series is designed to monitor the insulation resistance of unearthed main circuits (IT systems) AC, AC/DC 0…793 V resp. DC 0…1100 V. Solar systems containing inverters and isolating transformers are often designed as IT systems. iso-PV variants using the AMPPlus measurement method capable of adapting to slow voltage fluctuations meet the particular requirements of modern solar systems. Due to wide spatial distribution or EMC interference suppression methods often high leakage capacitances against earth occur in these systems. Considering this, the isoPV automatically adapts to the system conditions in order to optimise the measuring time. In particular, the requirements for permissible voltage ranges along with a low level of insulation can be met here.
Use the ISOMETER® isoPV in combination with the AGH-PV only. An external supply voltage allows deenergised systems to be monitored too.
