Abstract :
For the first time widely recognized transformation methods are analyzed within a unifying theoretical framework. The existence, uniqueness and stability of the estimate have been investigated. The results constitute a practical tool for convergence studies and can be used to compare metering system configurations, different load situations, etc.
