Data Validation:

The data compiled for the existing system has to be validated for correctness and consistency, especially in respect of load and network data. In the case of meter supplies, metering deficiencies within the form of non-functioning/defective meters have an impact on the correctness of loading/consumption figures. The proportion of non-working and defective meters should be identified. Check metering has to be done periodically on random sample primary. In case of un-metered supplies, the data would have to be worked out through sample metering and field studies. These measures would help in evolving appropriate mechanisms for data validation.
