Prepaid Metering

Prepaid metering is the state of art for single and three-phase although current metering, and should be implemented through utilities desirous of protecting their revenue. Among the various choices of types of prepayment meters, the key-pad based technology is far superior to other techniques such as smart cards as the latter is prone to tampers and is inconvenient to consumers.

The achievable level of losses is subject to several factors such as

  1. Configuration of the network;
  2. Physical parameters of the network;
  3. Level of loading; and
  4. Prevalent operating voltage levels, etc.

Therefore, with a view to meet the economic loss performance, target levels and maximum tolerable loss levels for every voltage level on the system might be taken as display in Table.
