1. Features
An advanced notebook computer is used in the tester as a master machine. Accurately metering the power, tubing and casing pressures load torque and rotation speed and the depth of dynamic liquid level and the other parameters.
Testing Function: three phase active power\reactive power\oil pressure\casing pressure\load\torque\curve of rotation speed synchronism detection\test for depth of dynamic liquid level.
Calculation Function: for calculating each testing curve and maximum\minimum\average value for each item;output pump efficiency\surface efficiency\downhole efficiency\systematic efficiency.
Analysis Function: based on each electric energy, the load and equilibrium level of the motor are analyzed for judging if it is operated correctly.
