Summary:The author describes a newly established precise mathematical model and CAD (computer-aided design) algorithms for a high-overload induction watthour meter (the software package is called WATTCAD). The problem of computing the dynamic induced magnetic and electric systems of the watthour meter is solved in WATTCAD with three new nonlinear equivalent circuits. The Monte Carlo method for tolerance analysis and an optimization technique have been programmed and improved for meter design. The user interface to WATTCAD was simplified and the amount of data to be entered minimized. The improved linear interpolation and secant algorithms are programmed for solving nonlinear equations of complex matrices which are used to describe the inductive electromagnetic phenomenon. As an example, the use of WATTCAD to design a new model watthour meter DD285 is discussed.< >
