Modal density of rectangular structures in a wide frequency range
آشنایی با موضوع
ضریب توان در یک سیستم الکتریکی متناوب واژای است که به نسبت توان واقعی به توان ظاهری گفته می‌شود و ضریبی بین ۰ تا ۱ دارد. توان واقعی در واقع توانایی یک مصرف‌کننده برای تبدیل انرژی الکتریکی به دیگر شکل‌های انرژی را نشان می‌دهد در حالی که توان ظاهری در اثر وجود اختلاف بین ولتاژ و جریان پدید می‌آید. با توجه به نوع بارها و میزان توان راکتیو آنها توان ظاهری می‌تواند از توان واقعی نیز بیشتر باشد.
فرایند تعدیل ضریب توان از مقادیر کوچکتر از ۱ به مقادیر نزدیک ۱ است. این فرایند ممکن است در طول انتقال انرژی الکتریکی و در پست‌های تبدیل ولتاژ انجام بگیرد چراکه به این ترتیب راندمان تبدیل ولتاژ بالا می‌رود. این فرایند همچنین در مراکز مصرف به ویژه واحدهای صنعتی نیز مرسوم است چراکه به این ترتیب گذشته از کاهش هزینه‌ها مربوط به تهیه انرژی الکتریکی هزینه‌های مربوط به انتخاب کابل و تجهیزات تغذیه نیز کاهش می‌یابد. که این فرایند با اتصال خازن به مدار انجام می شود و انتخاب مقدار خازن بستگی به بزرگی بار سلفی دارد. ضریب توان بالا در انتقال انرژی به ما کمک می کند تا در استفاده از هادی و دیگر تجهیزات صرفه جویی کنیم
