We would like to introduce examples of lightning damage countermeasures for electrical equipment at dams. Dams are located in mountainous areas with a high frequency of lightning strikes, and due to the distance between the monitoring station and the equipment within the dam body, an environment conducive to potential differences is created. Lightning strikes in the vicinity have caused damage to dam management equipment, and if the dam management system stops, it could lead to the worst-case scenario, making reliable lightning protection measures necessary. Our company has installed the VAJ series at the main power panel of the electrical room to protect the monitoring station's equipment from direct lightning surges, and we have provided grounding SPDs to equalize potential between grounding electrodes. [Case Overview] - Proposals for lightning protection measures suitable for the local situation and design of lightning protection panels - Implementation of countermeasures for equipment at risk of lightning surges, including meteorological observation devices, discharge warning systems, CCTV cameras, telephone lines, leakage flow meters, water level gauges, seismometers, audit corridor lighting, and signal lines between the monitoring station and each gate. *For more details, please download the PDF or feel free to contact us.
