Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount of electrical energy required by a specific consumer during a given period of time. MDI instruments record the base load requirement of electrical energy. They can also measure the peak load, but are unable to record sudden short circuit or high motor starting currents. The main parts of MDI are: 1. * Dial connected with moving system 2. * Pointer on dial 3. * Reset device 4. * Fraction device 5. * Indicating pin MDI is often available as a built-in feature of three phase energy meters.

  • الحمل الأقصى (بالإنجليزية: maximum demand)‏ هي أعلى قيمة للقدرة أو التيار أو الجهد... الخ ، خلال فترة محددة (يوم أو شهر أو سنة). ويتم تقدير القيمة القصوى للقدرة المستهلكة خلال فترات زمنية متساوية ومتعاقبة، أي كل ربع ساعة أو كل نصف ساعة مثلاً. (ar)
