| description | The article studies the dependences of active power losses in contacts and contact
systems of circuit breakers, contactors and magnetic starters on the main parameters
of electrical equipment. Models of functional dependences of active power losses
on nominal current for low-voltage switching devices of some manufacturers are
developed. Approximation functions of these characteristics have been compiled
and the value of determination coefficient of the obtained functions of active losses
and approximation error have been calculated. Graphical dependences of the
investigated parameters of low-voltage equipment are presented. |
