1.1.4.  Arc sensors ARC-SP, ARC-SL and ARC-SM

 

Sensors placed in the switchgear transfer the light information to the I/O units. 

 

Arc sensor ARC-SP

 

Figure: Arc sensor ARC-SP

 

 • 

Strong light is transformed to a current signal in the sensor

 

 • 

ARC-EP10/2.0 transfers the current signal to the master unit

 

 • 

Standard cable lengths 6 m and 20 m

 

 • 

The sensor type offers a cost-effective arc protection solution

 

 • 

Easy to install and replace

 

 • 

Normal installation involves one sensor in each switchgear compartment

 

 • 

Self-supervised arc sensor

 Arc 

fi bre sensor ARC-SL

 Figure: 

Arc 

fi bre sensor ARC-SL

 

 • The 

fi bre sensor is a durable glass fi bre, which is manufactured in lengths of 

 

  10, 11, 12, 13, 15, 20 and 25 metres (the active sensor length is always 5m less)

 

 • 

The detected light information is transferred to the ARC-EL3/2.0 unit inside the fi bre

 

 • The 

fi bre will be installed to go through the supervised compartments

 

 • 

Monitoring the light information with a fi bre system is a cost-effective solution 

 

  e.g. in low voltage switchgears with several compartments

 

 • 

Self-supervised arc sensor
