Applicable scope:
Mainly suitable for solid insulation materials such as plastic,
film, resin, mica, ceramics, silicone, glass, insulating paint,
etc. Measure the breakdown strength and withstand voltage time at
power frequency (48-62Hz) or corresponding DC voltage in air or
liquid medium. Suitable for continuous and uniform boosting or
stepwise boosting, apply AC/or DC voltage to the sample until
breakdown, measure the breakdown voltage value, and calculate the
breakdown strength of the sample; Using a rapid voltage increase
method, raise the voltage to the specified value and maintain the
sample without breakdown for a certain period of time. The
specified value at this time is the withstand voltage value of the
sample.

Usage: Take out the discharge rod and straighten the telescopic rod,
insert the other end of the grounding clip into the metal probe
socket of the discharge rod, and then clamp the grounding clip onto
the instrument grounding terminal A or B. Hold the insulated handle
as far away as possible from the instrument casing, stand, slightly
bend forward, open the glass door of the test box, and use the
metal probe to contact the high-voltage transformer output
equalization ball, sample electrode, and capacitor high-voltage end
one by one. (If necessary, after the discharge is completed, use a
multimeter in AC voltage range (AC20V range) to test if the voltage
between the electrode and the human body is less than 36V,
indicating that the residual voltage has been discharged
completely.)
Attention: Before taking out the sample after each experiment, it is
necessary to fully discharge it beforehand. During discharge, the
contact dwell time at each discharge point should exceed 2 seconds.
Safety instructions:
1. The equipment needs to be equipped with a separate protective
ground wire. Grounding the protective ground wire is mainly to
reduce the strong electromagnetic interference generated by the
sample breakdown on the surrounding area. It can also avoid losing
control of the computer.
2. The circuit of this testing equipment is equipped with multiple
protective measures, mainly including overcurrent protection,
voltage loss protection, leakage protection, short circuit
protection, DC test discharge alarm, etc.
3. Grounding requirements: A separate grounding is required, and
the grounding should comply with national standards. The metal rod
should be buried at least 1.5 meters underground.
4. The circuit of this testing equipment is equipped with multiple
protective measures, mainly including overcurrent protection,
voltage loss protection, leakage protection, short circuit
protection, DC test discharge alarm, etc.
Product features
1. Independent installation software running on the WIN
XP/WIN7/WIN8 system, with a user-friendly interface and simple
operation
2. Experimental display curve, automatic data storage, automatic
search.
3. multipurpose, can be used for accurate, reliable, and safe AC
and DC testing.
4. Computer controlled experimental process, automatic judgment
stop, automatic reset.
5. Multiple protections such as overvoltage, overcurrent, short
circuit, leakage, and misoperation.
Notes:
1. During the experiment, unrelated personnel should not be allowed
to approach, as this testing instrument can generate high voltage
and untrained personnel are not allowed to use the equipment.
During the experiment, there should be a supervisor and no one
should use it alone. In case of any unexpected situation.
2. If the equipment is not used for a long time, before reusing it,
first pressurize the instrument with no load, that is, remove the
wiring of the high-voltage electrode from the equalizing ball.
Check the computer test interface to see if the high voltage is
normal.
3. In case of unexpected situations during the experiment, the
power should be cut off in a timely manner, and the experiment can
only continue after the problem is resolved.
4. The equipment should be placed steadily and the ground should be
sturdy. It is best to use a cement floor to avoid resonance.
5. The casing of the device should be grounded to a protective
ground wire during use, ensuring the safety of operators and
equipment operation.
6. After using the equipment, turn off the power to all parts of
the system and do not plug or unplug the power cord with
electricity.
7. Connect the equipment according to the prescribed power supply
voltage. Ensure that the circuit wiring is correct. Otherwise, it
will damage the equipment.
8. The instrument needs to be placed indoors, and the laboratory
should be clean, dry, and free of corrosive media. Non relevant
personnel should not operate it casually.
9. Do not let the equipment cable touch the sharp edge to avoid
scratching the cable insulation; Do not let the cable be pressed
under heavy objects to avoid breaking the cable and causing a fire;
Do not use cables to pull or bind objects, as this can cause the
equipment to malfunction due to cable breakage.
10. Don't let the equipment get splashed with water, corrosive
gases, flammable gases, and combustibles.If not avoided, fire may
occur.
11. When moving equipment, cut off the power supply and pull the
plug from the socket. Do not place the device upside down or tilt
the device at an Angle greater than 45°when moving the device.
12. Do not unplug the power plug of the device while it is running.
