4. Information on maximum demand indicator Maximum Demand Indicator (MDI) is an instrument for measuring the maximum amount[clarification needed] of electrical energy required by a specific consumer during a given period of time.[1] 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 s tarting current. 4

5. Working of maximum demand indicator The energy consumed for an integrating time period (15 or 30 minutes) is indicated by the pointer on the dial. The pointer is driven by the pin. After this time period, the reset device comes into action and makes the pin return to its zero position as explained earlier. But the pointer continues to indicate the same reading. The pin starts indicating the energy consumed in the next time period. 5

6. consumption increases beyond the previous consumption value, which is being indicated by the pointer then only the pointer moves further, otherwise, it will be stable at the same position. The Merz-Price maximum demand indicator is also known as average demand indicator since the average maximum demand can be obt ained by maximum demand indicator. 6

7. Application of maximum demand indicator High accuracy in the maximum demand measured Ezoic The scale is uniform Disadvantages of Maximum Demand Indicator : The use of a gearing mechanism makes the construction complicated and increases the 7

8. Information on four Quadrant metering Four quadrant metering can be used to understand individually or collectively: Real Power consumed by the end user Apparent Power delivered by the utility Real Power delivered to the utility by an end user's generation source Apparent Power generated by the end user's generation source Having these measurements allows . 8

9. 1St Quadrant Quadrant I is defined as an area where both powers flow positively. Both are delivered to the consumer load. In many cases the CLOU terminology is forward. The power factor is lagging, we have inductive influence. The IEC literature is using the term import. In this quadrant we have Import of active power and Import of reactive power. 9

10. 2nd Quadrant In quadrant II, reactive power is positive and active power flows negatively. In many cases the CLOU terminology is reversed. The IEC literature is using the term export. 10

11. 3rd Quadrant In quadrant III, reactive and active power flow negatively (both powers are received from the customer). This is also a export condition. 11

12. 4th Quadrant In quadrant III, reactive and active power flow negatively (both powers are received from the customer). This is also a export condition. 12
