LIMITATIONS OF ENERGY AUDIT
The losses arrived at can at best indicate only the range of losses but not a very accurate figure on account of the following constraints.
• High cost of metering at EHT & HT points. As meters are to be connected using instrument transformers CT & PT for stepping down the primary parameters to levels acceptable by meters the errors in the CT & PT together with errors in meters add up to inaccuracies. The high multiplying factors cause to magnify even small errors in registration of reading.
• Simultaneous reading of all meters at every metering point is not possible unless an expensive automatic logging is provided.
• Near impossibility of reading meters at all consumers at one time. Each State Electricity Board have about 10 million consumers spread over vast area. Also SEBs have different meter reading cycles such as monthly, bi-monthly, trimonthly etc., by grouping number of services.
• Assessed consumption at services with defective meters to be added up to sales.150
• Assessed consumption of unmetered services such as agriculture, have large bearing on arriving at the T&D losses.
