انخفاض الجهد الناجم عن ضربات البرق - في لوحة التوزيع (HIOKI)

الإعداد

  1. موقع: HIOKI headquarters building, East side, 5th floor, 1-المرحلة 3 أسلاك, 200V distribution panel
  2. Measured period: From June 9, 2002 to August 9, 2002

مشكلة & تحليل

4 voltage dips caused by lightning were detected during measurement (different period than Case Study 4). The distribution panel (1-المرحلة 3 أسلاك) was affected by the voltage dip that occurred at the high voltage distribution network. The table below shows the residual voltage and period of each voltage dip. Voltage dips caused by lightning cannot be prevented by power distribution companies. لذلك, users should take appropriate countermeasures such as connecting a UPS to their PCs.
