2. When using this instrument, the user must follow the “Safety Regulations†section 168 and install two obvious disconnection points before the working power enters the tester. When changing the test sample and wiring, the two power disconnect points should be disconnected first.
3, before the test, please check all test wiring, control box, double pressure tube and the test product ground wire is connected. The test circuit grounding wire should be grounded according to the requirements of this instrument manual.
4, the discharge of large capacitance test sample application TPZGF special discharge resistance rod discharge on the sample. Discharge rod can not be immediately exposed to the sample, should first gradually close the discharge rod sample, to a certain distance air gap began to discharge, there is a hum, when there is no sound discharge rod discharge, and finally directly connected to the ground Discharge.
5. When the DC high voltage is 200KV and above, although the tester wears insulated shoes and is located at a safe distance, due to the influence of the high voltage DC ion space electric field distribution printing, several nearby DCs may have different direct currents. Bit. The test personnel should not shake hands or touch the grounding body by hand, otherwise there will be a slight electric shock phenomenon. This phenomenon is more obvious in dry areas and winter, but due to the small energy, it will not cause harm to the human body.
6, DC high voltage generator control box power supply AC AC220V ± 10%, 50Hz. If the power supply is isolated by 1/1 or if spontaneous power is used in the field, the power supply must be connected to earth ground.
