Safety Warning

● Those operating DC HV generators must be professional staff with electrical and HV test certificate.

● Provisions of Working Regulation of Power Safety should be strictly observed when using the equipment. There should be a clear cut-off point in the working power supply, which should be cut off clearly in case of replacement of test object and wiring.

● Before the test, it is necessary to make the connection of ground leads of tester control box, voltage-multiplying cylinder and sample reliable; the one-point grounding is conducted as shown in Figure 4-5.

● For large-capacitance test objects, a 100Ω/V resistance discharging rod should be used; the case that no discharging rod is passed through but ground lead is directly connected to the test object is prohibited.

Proper method of discharge: Firstly, make the top metal tip of discharging rod gradually close to the test object, then a hissing sound will appear when it comes to a certain distance, indicating that air gap begins to discharge free. When there is no discharge sound, the top tip of the discharging rod can be used to contact the test object for discharging, and finally the ground lead is connected directly to the test object.

● In case of 200kV+ DC HV tests, although testers wear insulated shoes and stａnd in a safety area, those persons standing nearby will carry different DC potentials due to HV DC ion space electric field distribution. There will be a slight shock occurred in testers when contacting with each other or the grounding body, which is more obvious in dry areas and in winter; however the energy is small and will not generally cause harm to human body.

● In the tests that discharge impact may be possible (test object breakdown), if the voltage rising is controlled by a host computer in a remote control manner, then the mode of isolating source and electrical isolation (optical fiber or radio) should be applied. Otherwise, the discharge impact may cause damage to the host computer instantaneously.
