The low slip test is used to determine the D and Q axis impedance of salient pole machines. The machine terminals are short circuited, each phase voltage and current are measured. Since the terminals are short circuited, machine voltage must be reduced to prevent excessive output currents that would damage the machine.
The test equipment used to test high voltage cables is a hi-pot test where a high DC voltage is a applied to the cable. This voltage can be from 150% to 200% of the working voltage of the cable.See related links below.
It is the rated test voltage that will not cause insulation breakdown.

Stick-slip machines are designed to provide more controllable motion than a traditional electric motor. The basic design consists of a motor a control board and a stick-slip mechanism. The motor is used to provide the power to move the stick-slip mechanism while the control board is used to regulate the speed and position of the mechanism. The stick-slip mechanism consists of an elastic element such as a spring or rubber band that is connected to a shaft. When the shaft rotates the elastic element is compressed and then released creating a stick-slip effect. To design a stick-slip machine the following steps must be taken: Choose an appropriate motor and control board. Design the stick-slip mechanism and select an appropriate elastic element. Select the appropriate shaft and bearing system. Integrate the motor control board stick-slip mechanism and shaft into a single system. Test the system and adjust as necessary for optimal performance.By following these steps it is possible to design and build a reliable controllable stick-slip machine.
Working Voltage is the voltage at which the boot is safe at. Test Proof voltage is what the boot was tested up to before it failed. However you must keep in mind that if you are in wet conditions that can significantly lower the rating of the boot. Also voltage does not kill you it is the amperage.
The term electrical checks will differ with respect to the machine or system being referenced. Electrical checks on a car will include the DC battery Voltage, charging voltage and current and may be voltage during engine starting. On a machine it could be main voltage secondary control voltages and even specific test point voltages on a control board.

A test done on a transformer. The voltage at the power frequency is ramped up to verify the transformer is capable of handling the stresses due to switching and natural phenomena (lighting strikes).Withstand Voltage:The voltage which has to be applied to a test object under specified conditions in a "withstand test" is called the "withstand voltage".
