A Study for Analysis of Poor Contact Signals of Electrical Connector

This paper is purposed to analyze current and voltage waveforms and thermal characteristic for poor contact of electrical connector(breaker load connector). In this paper, current and voltage waveforms by loads(lamp, drill and electric heater) and thermal data by poor contact are analyzed distinguishing data for normal state. The current and voltage waveforms can not easily distinguish between poor contact and normal state. Thermal characteristic without vibration is generated thermal energy different then normal state and after 20 minute, breaker load connector is generated high thermal energy of over 21 0℃. Therefore, the poor contact data are referred and applied by poor contact basic data of current and voltage waveforms and thermal data.
