Speed Sensing & Protection
The digital governor controllers from L&S Electric have at least two redundant speed channels. First, they process the signal coming from the potential transformer (PT), secondly, they also measure speed from pulses generated by Pick-ups. For the latter application, L&S Electric supplies a Speed Signal Generator (SSG).
For those application that may require a Mechanical-Hydraulic Overspeed protection, we also provide a Mechanical Overspeed Device
