Overspeed Relay
All electronic turbine governors from Hymatek Controls can be delivered with built-in over–speed protection. This function is also available in a separate apparatus, TUVA.
TUVA® 2x
TUVA measures the rotation speed of the machine and provides output signals for different speed levels which in turn is used in the control and monitoring of the machine. Total 8 speed levels are available. The levels can be adjusted and covers the area from standstill to overspeed.
TUVA also acts as a protection unit that signal critical speed. TUVA is designed as a standalone product, but is often installed together with a turbine governor. Redundancy in the functionality can be achieved by the use of a turbine governor or alternatively with a secondary TUVA device.
The device is available in several versions:
- TUVA 20: Over-speed protection, standard single-channel design delivered on the Connexi® platform
- TUVA 22: Over-speed protection, two-channel design with redundant electronics delivered on the Connexi® platform
