Abstract
A method and an apparatus for monitoring an electrical power or current consuming device. In the method for monitoring a first time point at which a current value for current passing through the consuming device exceeds a first current threshold value and/or a second time point at which the current value drops below a second current threshold value is first measured. Then first time point and/or the second time point are compared with each other or with other variables, especially a starting time for a control signal for controlling the consuming device, to establish plausiblity.
Claims8
A method for monitoring an electric power or current consuming device, said method comprising the steps of:
- a) measuring at least one of a first time point at which a current value for current passing through the consuming device exceeds a first current threshold value and a second time point at which said current value drops below a second current threshold value;
- and
- b) comparing at least one of said first time point and said second time point measured in step a) with at least one of each other and with other variables to establish plausiblity.
An apparatus for monitoring an electrical power or current consuming device, said apparatus comprising
- means for measuring at least one of a first time point at which a current value for current passing through the consuming device exceeds a first current threshold value and a second time point at which said current value drops below a second current threshold value;
- and
- means for comparing at least one of said first time point and said second time point with at least one of each other and with other variables, in order to establish plausiblity.
