SEL-TWFL — traveling wave fault locator and recorder for overhead lines
SEL-TWFL locates line faults using traveling wave and impedance methods. The device has a built-in 12-channel megahertz-range recorder, and one unit monitors two substation lines.
- Methods
- traveling wave and impedance
- Accuracy
- within one tower span
- Channels
- 12, recording at a frequency in MHz
- Lines
- overhead, cable, mixed, with series compensation; 2 lines per 1 device

Description
Traveling wave accuracy is within one tower span, so the crew goes straight to the required section. The locator works on overhead, cable and mixed lines and on lines with series compensation, 2 lines per 1 device.
The impedance method complements the traveling wave method.
