Safe Inspection of Solar Installations with High Voltage
Solar installations (also known as photovoltaic or PV installations) are becoming increasingly high-voltage
in order to reduce costs and improve the efficiency of power generation systems.
As a result, it is important to select measuring instruments
that support higher voltage measurement to protect the safety of inspection workers.
The P2000 enables high voltage measurement up to CAT Ⅲ 2000 V
by simply connecting to a compatible Hioki clamp meter or digital multimeter.
Why is CAT III 2000 V capability necessary?
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. As part of a transition to a new standard (IEC61010-2-030:2017) in 2017, measurements of solar installations were classified as CAT III.
Against this backdrop, measuring instruments used in maintenance of solar installations must accommodate high voltages to ensure they can be used safely. Using instruments that can accommodate the appropriate measurement category serves to protect workers and equipment from serious accidents such as electric shock and burnout.
Currently, adoption of 1500 V solar installation is growing, but instruments that can accommodate even higher voltages will be necessary in the future as larger and even more efficient systems enter into use.
Hioki developed the P2000 to support CAT III 2000 V measurement in response to the near-term prospect of such applications.
