Sejauh mana anda faham tentang harmonic distortion, adakah ianya hanya berlaku di LV site atau sebaliknya dan berikan sebab serta cara mengatasinya.

Harmonic Ditortion (HD)  is 'dirty energy'.. boleh menyebabkan breaker trip x tentu pasal (jadi sensitif) sebab CT jadi x betul dan macam2 lagi masalah..Penggunaan peralatan elektronik yg meluas ketika ini, menjadi penyumbang kepada masalah HD.. Harmonic menyumbang kepada masalah power quality..Harmonic boleh diatasi dengan penggunaan filter (capasitor)..

harmonic boleh dipantau@ check guna fluke meter yang ada fungsi harmonic..Meter tu juga boleh memaparkan bentuk gelombang harmonic (gelombang voltan vs arus) dan siap boleh kira berapa total harmonic distortion (THD).. Memang canggih la, tp meter jenama fluke ni agak mahal di pasaran..Cara nak check dia mudah je, macam guna thong amp..kemudian set kan pada fungsi harmonic..akan keluar paparan bentuk gelombang siap dengan bacaan harmonic sekali..
