RX9201 Insulating Oil Dielectric Strength Tester
I. Overview
This product is a new type of machine designed in accordance with the international standard IEC156 "Method for Determination of Dielectric Strength of Insulating Oils" and the requirements of national standard GB507-86, fully considering the needs of users at home and abroad.
This machine uses digital display and locking technology, with intuitive readings and high measurement accuracy: it takes into account the standard electrodes used domestically and internationally such as spherical, spherical cap, large flat plate, and the non-standard electrode of small flat plate with small gap, so that users can meet various requirements with one machine. This machine adopts advanced technology, provides a special high-strength insulating transformer, offering a maximum measurement range of 0-60KV, and is small in size and light in weight; as long as the standard ground wire is properly grounded, safety is ensured; when the oil breaks down, the overcurrent protection automatically cuts off the power within 0.02 seconds; this machine is safe and reliable, fully meeting the requirements for dielectric strength testing of various insulating oils.

III. Insulating Oil Dielectric Strength Tester Usage Method:
(1) Preparation
1. Use single-phase AC power supply 220V, and the grounding terminal on the shell must be connected to a standard ground wire.
2. Carefully install and check the oil cup, paying attention to the axis of the two electrodes. Adjust the electrode gap to: small flat plate: 1.25mm, others 2.5mm.
3. Turn on the power program switch, the power indicator lights up, and the voltmeter displays 00.0, indicating that the machine is working normally. (A few digits of error in the display is normal and does not affect test accuracy).
4. Before raising the voltage, the voltage must be lowered first, then the voltage rise test can be performed, otherwise the action will be refused.
(2) Insulating Oil Dielectric Strength Tester Test
1. Slowly pour the prepared oil sample into the oil cup, rinse it twice, then fill it with the oil sample, place the oil cup on the electrode holder, and close the oil cup cover to press the interlock switch. (If the oil cup cover is not closed, the action will be refused).
2. Let it stand for 10-15 minutes to remove air bubbles.
3. Press the voltage rise switch to automatically raise the voltage. When the oil breaks down, the overcurrent protection relay and protection system device will operate, cutting off the power to the device within 0.02 seconds, and the digital display will show the breakdown voltage value of the oil.
4. Press the voltage lowering switch, the voltage regulator automatically returns to zero, and after five minutes, the second test can be performed.
5. During the test, if the external voltage is insufficient, even if the digital display has not reached 60KV, the voltage regulator turntable may have already touched the limit switch.
6. During the test, if abnormal conditions occur, press the stop switch to forcibly cut off the high voltage power supply (when testing again, reset the stop switch).
IV. Precautions:
1. This instrument must be used in an environment equipped with a standard ground wire.
2. Keep the oil cup filled with clean and dry oil at all times to protect it.
3. Regularly wipe the electrode surface with soft leather or silk cloth to keep it clean and smooth.
4. With proper use and maintenance, users generally do not need to repair faults. Do not open the case arbitrarily. If the machine does not work properly, please contact our company promptly.
V. Insulating Oil Dielectric Strength Tester Maintenance Matters:
1. After use, place it in a dry, ventilated indoor area without corrosive gases.
2. If the instrument malfunctions, it should be inspected and repaired by professional personnel. Non-professionals are not allowed to inspect or repair it, and Insulating Oil Dielectric Strength Tester should not be opened by non-professionals, otherwise accidents may occur.
3. This product has a one-year warranty. During the warranty period, any quality or technical issues will be repaired free of charge. For damage caused by improper operation or negligence of the user, we provide preferential services.
