PV-ISOTEST HT Instruments Insulation Meter

PV-ISOTEST HT Instruments Insulation Meter

Multifunction device for checking electric safety and performance of a photovoltaic system

Features:

Multifunction instrument for electrical safety testing and troubleshooting of photovoltaic systems up to 1,500V DC.

• Insulation measurement up to 1,500V DC even on live systems
• Localization of the faulty module through the new GFL function
• Continuity of the protective conductor with 200mA

PV-ISOTEST represents a real innovation in the panorama of PV verification and testing instrumentation. PV-ISOTEST measures the insulation resistance of a single module, a string or even an entire photovoltaic field up to 1,500 V DC according to IEC/EN62446 standard. Traditional insulation meters would require a DC-rated switch-box to short-circuit the positive and negative terminals of the module/string/PV field under test. With PV-ISOTEST the use of any external device is not required, PV-ISOTEST carries out the measurements in full autonomy and self-sufficiency. In addition, through the new GFL (Ground Fault Locator) function, PV-ISOTEST indicates the position of any poor insulation on a string of the photovoltaic system, due, for example, to water or humidity leakage.
