Romero Engineering Company on Instagram: "This example shows Mho ground distance protection on a 230 kV transmission line using an SEL-411L relay. Zone 1 is set to 80% reach for high-speed protection, while Zone 2 is set to 120% reach with a time delay to coordinate with the remote substation. This is a typical starting point for transmission line distance protection design. #DistanceProtection #PowerEngineering #ProtectionRelays #SEL411L #GroundDistance #ElectricalEngineering"
