<p>The device (10) has a high current generation unit (11) that is provided to generate a measurement current for the resistance measurement, and to feed the measurement current into an electrical power switch (1) coupled to a measurement unit (12). A time-resistance curve of the switching contact (5) is determined in response to the opening or closing of the switching contact, based on measurement current and measurement signal. A main portion is provided with a housing (16) in which the high current generation unit and the measurement unit are accommodated. An independent claim is included for method for measuring a resistance of a switching contact of an electrical power switch.</p> |
