Talk about the high voltage test transformer test process precautions
1. Description
Naipu G series Gravel and sand slurry pump is
designed specifically for continuous pumping of extremely aggressive
slurries, with a wide particle size distribution. Capable of handling
large particles at consistently high efficiencies results in low cost of
ownership. The large volume internal profile of the casing reduces
associated velocities further increasing component life.

2. Pick up the working circuit according to your test. The test transformer housing and the operating system housing must be reliably grounded. The X terminal (high voltage tail) of the high-voltage winding of the test transformer and the F terminal of the measurement winding must be reliably grounded.
3. Before the power is turned on, the voltage regulator of the operating system must be turned to the zero position to turn on the power, switch on, and start boosting.
4. From zero, rotate the regulator handwheel at a constant speed to boost the pressure. Boosting methods include: fast boosting method, that is, 20s step-by-step boosting method; slow boosting method, that is, 60s step-by-step boosting method; extremely slow boosting method for selection. The voltage rises from zero from a certain boost mode and speed up to 75% of the rated test voltage you need, then rises to the required test voltage at 2% of the rated test voltage per second and pays close attention to the measurement. Instrumentation and the condition of the product being tested. If the indicator of the measuring instrument and the abnormal condition of the tested product are found during the boosting process or during the test, the pressure shall be immediately depressurized, the power shall be cut off, and the situation shall be ascertained.
5, this product must not exceed the rated parameters. In addition to the tests necessary, never voltage power or power off.
6. After the test is complete, the regulator should be returned to zero at a constant speed within a few seconds, and then cut off the power supply.
