11.1 Testing disturbance report
11.1.1 Introduction
M17101-2 v7
The following sub-functions are included in the disturbance report function:
• Disturbance recorder
• Event list
• Event recorder
• Fault locator
• Trip value recorder
• Indications
If the disturbance report is set on, then its sub-functions are also set up and so it is not possible to
only switch these sub-functions off. The disturbance report function is switched off (parameter
Operation = Off) in PCM600 or the local HMI under Main menu/Settings/IED Settings/Monitoring /
Disturbance report/DRPRDRE:1 .
11.1.2 Disturbance report settings
M11746-2 v7
When the IED is in test mode, the disturbance report can be made active or inactive. If the
disturbance recorder is turned on during test mode, recordings will be made. When test mode is
switched off all recordings made during the test session are cleared.
Setting OpModeTest for the control of the disturbance recorder during test mode are located on the
local HMI under Main menu/Settings /IED Settings/Monitoring/Disturbance report /DRPRDRE:1.
11.1.3 Disturbance recorder (DR)
M11750-2 v7
A Manual Trig can be started at any time. This results in a recording of the actual values from all
recorded channels.
The Manual Trig can be started in two ways:
1. From the local HMI under Main menu/Disturbance records .
1.1. Enter on the row at the bottom of the HMI called Manual trig.
A new recording begins. The view is updated if you leave the menu and return.
1.2. Navigate to General information or to Trip values to obtain more detailed information.
2. Open the Disturbance handling tool for the IED in the plant structure in PCM600.
2.1. Right-click and select Execute manual Trig in the window Available recordings in IED.
2.2. Read the required recordings from the IED.
2.3. Refresh the window Recordings and select a recording.
2.4. Right-click and select Create Report or Open With to export the recordings to any
disturbance analyzing tool that can handle Comtrade formatted files.
Evaluation of the results from the disturbance recording function requires access to a PC either
permanently connected to the IED or temporarily connected to the Ethernet port (RJ-45) on the front.
The PCM600 software package must be installed in the PC.
