HT Italia PV-ISOTEST: Advanced 1500VDC Photovoltaic System Tester

Photovoltaic technology is advancing, with installations increasingly designed for higher voltages, such as 1500VDC, to enhance power generation and operational efficiency. This evolution necessitates the use of sophisticated tools for accurate verification, ongoing maintenance, and ensuring the safety compliance of these systems.

Introducing the PV-ISOTEST by HT Italia

The HT Italia PV-ISOTEST is engineered to meet these critical requirements. It stands as a leading instrument for performing essential safety checks on photovoltaic systems operating up to 1500VDC, fully compliant with the international standard IEC/EN62446-1.

Key Features and Functions

• Dual Mode Insulation Testing

  Provides immediate OK/NO results for insulation resistance of active conductors within modules, strings, or entire PV fields, simplifying fault identification without external switches.

• Ground Fault Locator (GFL)

  Precisely pinpoints the location of single low insulation faults within a PV string, aiding in the diagnosis of issues potentially caused by environmental factors like moisture.

• Timer Mode Insulation Testing

  Evaluates the quality of cable insulation by calculating the Dielectric Absorption Ratio (DAR) and Polarization Index (PI), which are indicative of the insulation's condition, especially for older or longer cables.

• Protective Conductor Continuity (RPE)

  Ensures the integrity of protective conductors through testing with a current exceeding 200mA, verifying essential safety connections.

• Digital Multimeter (DMM) Functionality

  Offers immediate display of DC and RMS voltages, including any AC components, measured between the system's poles and the earth.
