Digital oscillographic recorders are used for power efficiency tests in hydroelectric power plants.
Hydropower generates electricity by rotating a generator from the pressure of water from a dam. Changing the opening (stroke) of the guide vane will change the rotation speed of the generator, which affects the amount of power generated and frequency. Governor tests (load cut off) are performed to confirm the correct functioning of no-load operation in the event that the load is cut off due to an accident during power generation. During this time turbine rotation speed, generator voltage, iron pipe water pressure, and other factors must not exceed a specified range.
The RA2300MKII is equipped with a strain amplifier and can also fit a pressure sensor and displacement sensor.
