5.3.1 Basic parameters
Set the basic parameters:
• Connection type
• Voltage
– Direct measurement on the system or using voltage transformers
– Measuring input voltage in the case of direct measurement on the system
– Primary and secondary voltage in the case of measurement using voltage transformers
• Current
– Primary current
– Secondary current
You can find additional information in chapters Operation (Page 43) and Parameterizing
(Page 49).
Example
You want to measure in a 3P4W 10 kV system using voltage transformers (10000 V/100 V)
and current transformers (100 A/5 A).
1. Select the "BASIC PARAMETERS" submenu of the "SETTINGS" menu.
Specify the connection type and the ratio of the voltage transformers you are using in the
"VOLTAGE INPUTS" menu item.
The ratio of the voltage transformer you are using can be only be adjusted when the
setting "USE PTs" is activated.
2. Confirm your entry and press the <F1> key to return to the "BASIC PARAMETERS" submenu.
Specify the ratio of the current transformers you are using in the "CURRENT INPUTS" menu
item.
3. You can configure the resolution of the current display in the "DISPLAY RANGE" menu item.
The setting has no impact on the measurement accuracy of the device.
The recommended setting is the current that is usually flowing in the system. If the usual
current is 50 A, set the display range to 50 A. In this case, the current is displayed with one
decimal place.
