در عصر جنگ جریان‌ها در اواخر دهه ۱۸۸۰ جرج وستینگهاوس و توماس ادیسون با هم دشمن شدند. به خاطر توفیق ادیسون در استفاده از جریان مستقیم برای توزیع توان الکتریکی به جریان متناوب که از سوی چندین شرکت اروپایی حمایت می‌شد. وستینگهاوس الکتریک در پیتسبورگ، پنسیلوانیا واقع شده بود.[۱]

سابقه[ویرایش]

در طول اولین سالهای توزیع برق جریان مستقیم ادیسون استاندارد آمریکا بود. جریان مستقیم به خوبی با لامپ‌های رشته‌ای، که بار اصلی از روز بود، و موتورها کار می‌کرد. سیستم جریان مستقیم می‌توانست به طور مستقیم توسط باتری‌ها ذخیره شود که به هنگام وقفه مولد منبع با ارزشی بودند. مولدهای جریان مستقیم به راحتی می‌توانستند موازی شوند. ادیسون دستگاهی برای اندازه‌گیری میزان مصرف مصرف کنندگان و پرداخت قبض ساخته بود که فقط برای جریان dcکار می‌کرد. در سیستم جریان dc استفاده از موتور ac تعریف نشده بود. بازده تبدیل از اولیه ترانسفورماتور هسته‌ای دو قطبی باز بسیار کم بود. سیستم‌های acاولیه از سیستم توزیع توان با اتصال سری استفاده می‌کردند که نقص ذاتی داشت و خاموشی یک چراغ منجر به خاموشی دیگر اتصالات در آن مدار می‌شد. که سیستم dcاین مشکلات را نداشت.[۲][۳]
