resistance box resistors of generator neutral point for tower crane

 The sliding rheostat can change the resistances of the connected circuit and act as a continuous change of current size, but can not know the resistance value of the connected circuit accurately.If you need to know the resistance of the connected circuit, the resistance box will be used.

Resistance box is a rheostat that can adjust resistances and can display resistance resistance.

It is compared with a sliding rheostat, and a sliding rheostat cannot represent the resistance of a connected circuit, but it can change the resistance in the access circuit continuously.The resistance box can indicate the resistance value of the connected circuit, but the resistance change is discontinuous and there is no sliding rheostat.
