<p>The invention relates to a contactor detector (100), which can be arranged into a functional relationship with a contactor, which contactor detector comprises detecting means for detecting the failed contactor. The contactor detector (100) further comprises a programmable control unit (101), which can be arranged to generate and send an identification code, with which the defective contactor can be identified. The invention further relates to a contactor detector system, which further comprises a monitoring device (200), which has been arranged into a functional relationship with the contactor detector (100), and a method for identifying the contactor. In the method the variable describing the contactor state for detecting the failure of the contactor is measured by the detecting means of the contactor detector, and an identification code is generated and sent to a monitoring device by a programmable control unit (101) of the contactor detector (100) for identifying the failed contactor.</p> |
