News - General T&MHIOKI launches PV Power Verifier27 May 2013 - Hioki E.E. Corporation launches the Photovoltaic Power Verifier LR8400-92 and LR8400-93. In addition to estimating optimal electricity generation for photovoltaic solar power systems, the PV Power Verifiers measure actual generation. By comparing expected power with actual power, energy auditors and maintenance technicians can assess whether solar power generating systems are operating properly. If an equipment failure is suspected, the instruments can also be used to pinpoint its location. Hioki test and measurement products simplify maintenance and management compared to what is possible with older instruments, dramatically increasing the level of convenience for customers. The PV Power Verifier LR8400-92 includes a 200 A AC/DC clamp on current sensor, while the LR8400-93 includes a 2000A AC/DC clamp on current sensor. The LR8400-92 and LR8400-93 use channels 1 and 2 to measure actual electricity generation and channels 3 and 4 to estimate optimal generation based on the following architecture:
Hioki is in the process of patenting this approach to measuring photovoltaic solar power system performance, which is the first of its kind in the industry. Related Articles: |
