Tanpa jalur tersebut, sambaran dapat merambat melalui struktur rumah dan menimbulkan kerusakan atau kebakaran yang lebih parah.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Apakah stop kontak surge protector sudah cukup?<\/strong> <br \/>Surge protector biasa hanya meredam lonjakan tegangan ringan dan tidak dirancang untuk menahan sambaran petir secara langsung. Untuk perlindungan menyeluruh, kombinasikan dengan arrester, grounding, dan cara melindungi elektronik dari petir lainnya di atas.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Bolehkah mandi atau mencuci piring saat petir?<\/strong> <br \/>Sebaiknya tunda dulu, karena petir dapat merambat melalui pipa air dan instalasi listrik di dalam rumah. Badan Cuaca Nasional Amerika Serikat juga menyarankan menjauhi jendela dan pintu selama badai petir berlangsung.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\"><strong>Elektronik rusak tersambar petir, apakah masih bisa diservis?<\/strong> <br \/>Sebagian kerusakan akibat lonjakan tegangan terjadi pada power supply atau mainboard, sehingga masih bisa diperbaiki teknisi. Jangan menyalakan perangkat yang berbau hangus sebelum diperiksa, karena berisiko memicu korsleting lanjutan di rumah Anda.<\/p>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Petir memang tidak bisa dicegah, tetapi risiko kerusakan elektronik dapat ditekan dengan instalasi listrik yang aman dan terawat.
