(1) Power supply routine maintenance

 regular testing of the UPS AC uninterrupted power supply output voltage, frequency, output power, load power factor, waveform distortion, phase deviation, three-phase voltage unbalance.

Maintenance and detection period: at least one full test per quarter.

(2) All types of generator sets routine maintenance

 regular testing of the output voltage, frequency,output power, frequency deviation of the generator set.

Maintenance and detection period: at least once every six months load test, test a comprehensive test of the power quality.

(3) The rectifier routine maintenance and efficiency testing.

(4)Communication power equipment fault diagnosis, troubleshooting.

(5)Routine maintenance of the AC voltage regulator and testing of the quality of power supply.

(6) Acceptance, installation and commissioning of newly installed UPS AC uninterrupted power supply.

(7)During the expansion and renovation, the maximum demand of electricity for the mobile base station related communication equipment is tested and calculated.

(8)Detect the power quality of the mobile base station in the field and track the cause of equipment failure.and automatically generate a written test report.
