I welcome all to this discussion.
Generally, we say that the algorithm giving fault location error of less than 5% is ok and lesser error indicates the superiority of the fault locator algorithm. Is any IEEE or other standard defines the limit of fault locator error?
This question is in the context of the transmission line protection.
Thank you for your time.
Fault location algorithm for transmission lines based on traveling wave phenomena is preferd and the obtained results are satisfied
The majority of defects are treated at a level above 10%, according to a review by ieee.
Ashraf Mohamed You rightly said, travelling wave methods have high accuracy.
Actually, my question is about the accuracy needed for fault locators or algorithms as per the IEEE or any other standards.

In the standard of Rosseti FGC UES (Russian energy company), the following errors are claimed:
1. ±1 % - for double-ended fault location;
2. ±2,5 % - for single-ended fault location.
Errors are claimed for 50 Ohm fault resistance.
