Are the Flicker values valid for a Delta, 2PT and 2CT system?
Causes and Fixes
Are the Flicker values valid for a Delta, 2PT and 2CT system?We are not aware of any standards that stipulate that the flicker values need to be based voltage phase to line values. As such, when the meter is in delta mode, the Flicker module in the meter detects this volts mode and calculates flicker data based on voltage line-to-line values. The accuracy of the calculation is the same whether line-to-neutral or line-to-line voltages are used.
Can you use 3 PTs instead of 2?
No. In delta mode only 2 PTs are required for V1 and V3 connections; V2 is calculated based off these values. The flicker module also uses the calculated V2 voltage to generate flicker data.
Can the Flicker module be made read-only?
The hardware-locked option locks all revenue related modules in the meter, but at this time there is no option to lock the Flicker Module as well. The way to proceed would be to enable Advanced Security and grant the user read-only access.
How to get flicker data?
The outputs of the Flicker Module need to be connected to a Data Recorder.
General information regarding the Flicker module or the Data Recorder module is available in the online help - ION Reference.
