Facility MaintenanceMaintenance service for power conversion facilities
In order to keep the mission critical facility of customer like UPS at the constantly prime and sound condition, we provide the proper advice on the preventive maintenance such as the recommendation of part replacements at the designated period and notice of any sign of product deterioration. In addition, given the high general hope on the renewable energy resources, there are growing numbers of soar farm projects in Japan. Our expert field service engineers on solar farm conduct periodic maintenance service.

Facility diagnosis
Diagnosis on the deterioration level of energy storage system
Energy storage battery unitsused in UPSs and DC power supply are the mission critical facilities since it prevents the load side systems from the dynamic volage dip of AC power supply and power outage.
We perform internal resistance measurement for storage batteries using the BATTERY HiTESTER as a standard inspection item for degradation analysis of control valve type lead storage battery. We also perform residual product life diagnosis by using the storage battery short-term capacity tester manufactured by B-BEST in line with the customers' requests. We will also help the customer in draftnig the suitable preventive maintenance plan for the facilities based on checks of the past measured data.
Thermographic diagnosis
Abnormalities on the solar panel are checked by thermographic diagnosis.
-
Infrared thermal imaging analysis on the back of panel
Heat bank was detected on the top -
Peeling is visually checked
-
When the panel was closely checked, we found a pinhole of 1 mm square.
