Terminal blocks pass insulation testing for photovoltaic
applications Testing ensures that terminals can withstand a
continuous voltage of 1000 V dc under all climatic conditions.
Specialized insulation testing is required for solar
photovoltaic (PV) applications because standard insulation tests
do not detect low-energy (partial) discharges, which are common
in PV applications. Weidmuller announces the completion of
specialized insulation testing on its terminals blocks geared
specifically for solar photovoltaic (PV) applications. This
testing ensures that terminals can withstand a continuous
voltage of 1000 V dc under all climatic conditions. Specialized
insulation testing is required for PV applications because
standard insulation tests do not detect low-energy (partial)
discharges, which are common in PV applications. Partial
discharges can slowly work through a terminal’s insulation line,
ultimately causing a defect. In addition, insulation lines react
differently to partial discharge tests for dc voltag
