- Hioki CAT III DC High Voltage Probe P2000
Safe Inspection of Solar Installations with High Voltage
Recent years have seen the introduction of solar power systems and EV batteries that operate at progressively higher voltages, creating new maintenance demand. At the same time, the hazards posted by maintenance work are increasing due to use of higher voltages.
Safety standards categorize measurement locations by measurement category ratings CAT II, CAT III, and CAT IV based on their line-to-ground rated voltage, current capacity, and transient overvoltage.
According to the standard for Photovoltaic (PV) module safety qualification (IEC 61730-1), PV modules are treated as the overvoltage category III, and an instrument categorized as Measurement Category III is required.
