Application scope 
It is used for the soft start and protection of H.V. squirrel-cage motor or asynchronously-started synchronous motor,with rated voltage range of 3kV ~ *5KV, especially fit for the industrial enterprises with insufficient power capacity.
 
Advantages
1.Predictable: Domestically advanced computer emulated software used so that the starting process can be analyzed.
2.Adjustable: The starting time, the resistance of the liquid resistor can be adjusted.
3. Controllable: The resistance of the liquid resistor can be adjusted so the whole starting process and the power systems voltage are also controllable.
4.Repetition availability: The initial value of the liquid resistor can be adjusted based on the ambient temperature and the proceeding starting temperature so as to maintain the stability of the starting process.
5.PLC controller with high reliability is adopted, which makes available the remote communication and central control and meets the requirements by DCS control system.      
Smooth starting process with no impact to mechanical system, motor and power systems
