Section 3 1MRK 506 335-UUS A Analog inputs Section 3 Analog inputs Introduction Analog input channels in the IED must be set properly in order to get correct measurement results and correct protection operations. For power measuring and all directional and differential functions the directions of the input currents must be defined in order to reflect the way the current transformers are installed/connected in the field ( primary and secondary connections ).
Section 3 1MRK 506 335-UUS A Analog inputs • Forward means the direction is into the object. • Reverse means the direction is out from the object. Definition of direction Definition of direction for directional functions for directional functions Reverse Forward Forward Reverse...

Section 14 1MRK 506 335-UUS A Monitoring Manual trigger A disturbance report can be manually triggered from the local HMI, PCM600 or via station bus (IEC 61850). When the trigger is activated, the manual trigger signal is generated. This feature is especially useful for testing. Binary-signal trigger Any binary signal state (logic one or a logic zero) can be selected to generate a trigger (Triglevel = Trig on 0/Trig on 1).

There are three LEDs on the local HMI (green, yellow and red), which will display status information about the IED and the Disturbance recorder function (triggered).
Section 14 1MRK 506 335-UUS A Monitoring The indication function tracks 0 to 1 changes of binary signals during the recording period of the collection window.

Section 14 1MRK 506 335-UUS A Monitoring 14.8.3 Signals 14.8.3.1 Input signals The trip value recorder function uses analog input signals connected to A1RADR to A3RADR (not A4RADR). 14.8.4 Operation principle Trip value recorder calculates and presents both fault and pre-fault magnitudes as well as the phase angles of all the selected analog input signals.
Section 14 1MRK 506 335-UUS A Monitoring 14.9 Disturbance recorder 14.9.1 Functionality The Disturbance recorder function supplies fast, complete and reliable information about disturbances in the power system. It facilitates understanding system behavior and related primary and secondary equipment during and after a disturbance. Recorded information is used for different purposes in the short perspective (for example corrective actions) and long perspective (for example functional analysis).
Section 14 1MRK 506 335-UUS A Monitoring Disturbance recorder collects analog values and binary signals continuously, in a cyclic buffer. The pre-fault buffer operates according to the FIFO principle; old data will continuously be overwritten as new data arrives when the buffer is full. The size of this buffer is determined by the set pre-fault recording time.

Section 21 1MRK 506 335-UUS A Time inverse characteristics Section 21 Time inverse characteristics 21.1 Application In order to assure time selectivity between different overcurrent protections in different points in the network different time delays for the different relays are normally used. The simplest way to do this is to use definite time delay.
