Making Fault Location Measurements
How to Make and Interpret Fault Location Measurements
NOTE Inspect or measure your cable for velocity factor and cable loss per 100
feet specifications. If your cable is not marked with these parameters,
you may refer to Appendix A for some typical values. The values in
Appendix A are typical only.
Automatically Determining Velocity Factor and
Cable Loss
An alternative to entering the velocity factor and cable loss of your cable
is to use the algorithm built in to the analyzer to determine these values
automatically. To use this function, you need a known length of cable of
the same type being measured that is at least 30 feet long.
Press the key and follow the prompts. See
“ ” in Chapter 8 for more information.
