تفاوت جریان زیاد و جریان اضافه بار

متن کامل
تفاوت جریان زیاد و جریان اضافه بار

جریان زیاد (overcurrent) هر جریانی بیش از جریان نامی هادی ها، تجهیزات و یا دستگاه‌ها در شرایط مورد استفاده است. اصطلاح "جریان زیاد" هم جریان اتصال کوتاه (short circuit current) و هم جریان اضافه بار (overload current) را شامل می‌شود.
پس در واقع هر اضافه جریان یک جریان زیاد است، ولی یک جریان زیاد ممکن است یک اضافه جریان نباشد. 



همچنین می‌توان گفت که یک اضافه جریان، جریان زیادی است که محدود به مسیر طبیعی جریان است و هیچ شکست عایق وجود ندارد، اما جریان اتصال کوتاه جریانی است که از طریق شکست عایقی یا اتصال خطا اتفاق می‌افتد.
