What is the overspeed trip set at for a turbine with a normal operating speed of 1870 RPM?

In the context of turbine operation, the overspeed trip is a crucial safety mechanism designed to protect the turbine from operating at dangerously high speeds. Typically, the overspeed trip is set at a percentage above the normal operating speed to provide a safety margin.

For a turbine with a normal operating speed of 1870 RPM, the overspeed trip is commonly set around 10% above this normal speed. Calculating this involves taking 10% of 1870 RPM, which is approximately 187 RPM, and adding that to the normal operating speed.

When you do the math:

1870 RPM + 187 RPM = 2057 RPM.

This calculated value aligns with the standard practices in the industry to ensure that the turbine does not reach a speed that could jeopardize its integrity or the safety of operations. Hence, setting the overspeed trip at 2057 RPM is a suitable and correct choice, as it effectively manages the risk of overspeed under operational conditions.
