Abstract
This study was done at ligtning detection system in Padang. The systems was consist of 3 electric field sensors with synchronous satelite GPS. Time of arrival and sensors coordinate was taken from each sensors. This data was used to calculate ligtning location by Time of Arrival Linear Spherical method. Then the distances between lighting and sensor can be calculated. The distances will compared with electric field waveforms recorded at lightning sensor to testing validity our results. After validity, lightning current peak can be calculated. 8 of 20 data sample are valid with lowest lightning current peak is -1,001 kA dan highest value is -2,661 kA.
Keywords : Lightning, Lightning Detection System, Time of Arrival Ligtning Current Peak.
Abstrak
Penelitian ini dilakukan pada sistem deteksi petir yang dibangun di kota Padang. Sistem terdiri dari 3 sensor medan listrik dan GPS yang tersinkronisasi. Perbedaan waktu datang dan koordinat sensor didapatkan dari masing-masing sensor. Data ini digunakan untuk mendapatkan lokasi kejadian petir dengan metode Time of Arrival Linear Spherical. Setelah lokasi petir didapatkan maka jarak antara stasiun dengan lokasi kejadian petir dapat diketahui. Jarak sensor dengan petir dibandingkan dengan parameter gelombang medan listrik yang terekam sehingga dapat diketahui validnya hasil perhitungan. Setelah hasil perhitungan valid maka arus puncak dapat ditentukan. Dari 20 data tersebut terdapat 8 data yang bentuk gelombang medan listriknya sesuai dengan jarak antara sensor dengan lokasi petir dengan arus puncak petir yang terendah berada pada nilai -1,001 kA dan tertinggi berada pada nilai -22,661 kA.
