Taking Test Point Readings

The ground connection test points are tied to the turbine or generator case ground.

The red Voltage test point is connected to the Shaft Voltage Metering Rope.

The green Ground Current conductor running through the faceplate allows the operator to measure ground current with a hand-held, clamp-on style ammeter. To determine the current direction, the left side of the wire is connected to the shaft grounding rope and generator shaft, and the right-hand side of the wire is connected to case ground.

The Metering Rope and Grounding Rope test points connect to each rope’s insulated wear indicator line.
