OVERSPEED MONITORING

OVERSPEED MONITORING

One of the most critical protection systems for rotating machinery. Overspeed control.

HEINZMANN developed the VOP O3 unit to monitor 3 speed probes with 2 out of 3 voting  to protect the machinery. Installed on many gas turbines and reciprocating engines alike. Gearboxes, turbos and other critical systems.

Overspeed Protection Unit

The VOP 03 is a Triple Voting Overspeed Protection Unit. It has 3 speed channels, each one monitored totally independently whilst the two out of three voting system considers the output from each channel. At least two of the channels must agree an over frequency and trip simultaneously for the overall voting contact to trip the turbine. Each channel can be tested while running and replaced, hot swap, while the machinery is running. The design provides protection from nuisance trips.
