17.12.4.3 Application example for OHL
Additionally, the PTRSTHR (51TF) function can be used to monitor faults on OHL. In such cases, the
OHL current and voltage shall be connected to W1 inputs. In case of one-and-a-half breaker
configuration, W1 and W2 currents shall be used.
For such applications, the PTRSTHR (51TF) function can be triggered either by the set phase
current level or externally by the START or TRIP signal from the distance protection. As a result, a
summary list that provides an overview about all through faults seen by the IED will be available on
the local HMI.

Function description
Current harmonic monitoring
17.13.2 Application
In order to maintain the power quality for better supply, harmonics in the system must be
monitored. Due to the nonlinear loads connected to the system, harmonics (apart from
fundamental frequency component) are generated and thereby the system voltage is distorted.
Voltage distortion appears to have a little effect on operation of nonlinear loads connected, either
phase-to-phase or phase-to-neutral. Current distortion is limited at the point of common coupling
PCC to control the harmonic current from the utility to the consumer. Thereby, the voltage
distortion must be limited in order to prevent it from spreading to other facilities.
