Settings for Medium Voltage Networks

When preparing a Logger for use, you can enter ratios for voltage and current, resulting
in the calculation and display of primary side values. For example, in 14 kV delta power
network, the primary side of a Potential Transformer (PT) might be at 14 kV potential,
and the secondary side might be at 100 V potential. There might be a Current
Transformer (CT) with a ratio of 1000 A to 5 A. For the Logger to display readings in the
14 kV and 1000 A range:
1. In the "Set up a logger for function P or A" screen, check the box for "Voltage
transformer" at the top of the screen. Entry boxes for Primary and Secondary
appear. Make the voltage entries as shown:
2. Open the Current menu. Check the box for Current Transformer, and enter the
current primary and secondary as shown:
