Chapter 3 Setup 17
3.3 Potential Transformer Ratio: Pt
Note: Pt must be defined before relay setpoint definition.
In a direct connection, at low voltage (up to 660V), the PT must be set
to 1. In the case of connection using PTs, the PT ratio must be
calculated.
Example: If the primary voltage is 165kV and the secondary is 110V,
the PT will be 165,000/110=1500.
