Linetroll
Linetroll 110Eμ
Linetroll 110Eμ is a line mounted indicator for detection of PtG and PtP faults in overhead line networks.
- Single distribution systems
- Distribution systems with earth-wire
- Multiple distribution systems
About Linetroll 110Eμ
The indicator is powered by replaceable long-life lithium batteries which have a life expectancy of 10-15 years. It provides a 360 degree visibility for indication both for transient faults and permanent faults.
