What are the main job responsibilities of Insulation Oil Dielectric Strength Tester Upgraded Version?
The instrument adopts fully digital closed-loop boost control technology. The complete test cycle from boosting → breakdown detection → automatic power-off protection → magnetic stirring → settling → re-boosting requires no manual intervention. It can automatically complete 1 to 6 repeated tests, automatically calculate the mean and standard deviation, and generate a test report that meets the standard requirements.When the breakdown voltage of insulating oil drops due to aging, moisture, or contamination, it directly threatens the safe operation of transformers and power equipment.
The operator sets test parameters (such as ramp rate, target hold pressure, hold time, and number of cycles) on the touchscreen.
After starting up, the instrument automatically ramps up the pressure at the set rate and then enters hold mode when the hold pressure is reached.
After hold pressure ends, if further testing is required (such as a multi-cycle breakdown test), the instrument automatically ramps up the pressure again (starting from 0 or the hold pressure value, following a set logic) until the preset number of cycles is completed.
Electrode material: Copper substrate + cyanide-free gold plating process
Surface roughness: Ra ≤ 0.02μm (mirror finish)
Electrode spacing positioning accuracy: ± 0.02mm
Gold plating thickness: ≥ 2μm
The surface finish of the electrode directly determines the uniformity of the electric field distribution, which in turn affects the repeatability and reproducibility of the test results.
In summary, the instrument's voltage-boosting and pressure-maintaining functions not only meet the core technical requirements of Insulation oil withstand voltage testing, but also adapt to multiple industry standards (domestic and international) through automated control, precise parameter adjustment, and multiple safety protections. This lowers the operational barrier and serves as a key functional module for ensuring the accuracy and safety of oil sample testing.

FAQ
Q1: How to handle damage upon arrival?
A: All instruments are packaged with three layers of protection (instrument shockproof packaging + inner box + export wooden crate), and are labeled with shockproof indicators. If any damage is found upon arrival, please take photos for record-keeping and contact us within 48 hours. We will arrange for a replacement or refund within 7 business days.
Q2: How often should the electrodes be replaced?
A: Under normal operating conditions (clean oil, free of serious impurities), gold-plated electrodes can be used for approximately 500-800 tests. If noticeable pitting, oxidation discoloration, or wear is found on the electrode surface, it should be replaced immediately. Wholesale customers are advised to stock electrode consumables at a ratio of 1:5.
Q3: Does the instrument support use in high-altitude areas?
A: The standard version is suitable for areas below 2000m altitude. If customers need to use it in high-altitude areas (such as the Qinghai-Tibet Plateau, the Andes Mountains, the Ethiopian Highlands, etc.), please specify this when ordering. We will provide a high-altitude version (with appropriate derating design for the high-voltage section).
