Italy HT Insulation Resistance Test/Fault Locator PV255s

PV255s Insulation Resistance Test Analysis and Ground Insulation Fault Locator

The PV-255s is a multifunctional instrument used to verify electrical safety and locate ground insulation faults in photovoltaic systems. It is a truly innovative instrument and is another tool developed by HT to measure the insulation performance of photovoltaic modules, photovoltaic strings, or the entire photovoltaic array according to the standard IEC/EN62446. The PV-255s test system voltage can reach up to 1500V DC, specifically designed for 1500V photovoltaic systems. Due to the innovative GFL (Ground Insulation Fault Localization) function, it provides inspectors with precise location of individual insulation faults that may exist on photovoltaic system strings, such as those caused by water or moisture infiltration.
