Abstract

Although modern vehicles are equipped with special electronic controller similar to programmable
logic controller (PLC) to reduce wiring harness and relays, switching elements have found more
and more place in vehicles with the increase of electronic circuits and safety requirements like
every aspect of industry.
In spite of its wide use, relays have some disadvantages because of being an electromechanical
part. Limited mechanical and electrical lifetime, influence from environmental conditions such as
ambient temperature, humidity, dust and contaminant gases, arc discharge between contacts and
subsequently material transfer and erosion on contact surface are some of them.
The main aim of manufacturers and consumers of relay is to remove these disadvantages and
subsequently to increase efficiency of relays. In this study, DC relays which uses automotive
applications, arc and arc caused a real problem belongs to an intercity bus electrical system will
be mentioned

Keywords
