Product Details
Brand: Huazheng
Model: HZJQ-X1
Portable Transformer Oil Dielectric Strength Test Equipment 100kV I. OVERVIEW HZJQ-X1 Transformer Oil Dielectric Strength Test Equipment is a device used to detect the dielectric strength of insulation oil, mainly used for oil quality testing of high-voltage electrical equipment such as transformers.
Typical Applications
Transformer oil acceptance testing - verify dielectric strength of new oil before filling
Routine oil quality monitoring - periodic BDV checks per grid company maintenance schedules
Post-filtration verification - confirm oil quality after regeneration or dehydration treatment
Fault investigation - assess oil condition after overheating, arcing, or moisture ingress
Laboratory and field testing - portable design for use at substations, workshops, and mobile test teams
High-voltage equipment oil sampling - applicable to circuit breakers, cables, and other oil-insulated assets

| PRECAUTION |
1. The selection, placing and electrode distance of the oil sample before testing shall meet relevant national and industrial standards. 2. The operators or other personnel are strictly forbidden to touch the casing after the power is switched on to avoid accidents. 3. The power shall be cut off immediately if any abnormal event is found during the operation. 4. For a new oil cup or after cleaning, perform 24 breakdown tests before actual testing. When not in use, the oil cup should be soaked in clean oil. |
| Why Transformer Oil BDV Testing Is Required |
The breakdown voltage (BDV) of insulating oil is a critical indicator of its breakdown voltage and overall condition. Degraded, contaminated, or moisture-laden oil cannot withstand normal operating voltage stress and may lead to internal flashover, insulation failure, and catastrophic transformer damage. BDV testing is specified in IEC 60156, ASTM D1816, and ASTM D877, and is required during oil filling, routine maintenance, after filtration, and following any suspected contamination event. Regular BDV monitoring helps utilities and industrial operators decide when oil regeneration, filtration, or replacement is needed - before insulation failure occurs. The HZJQ-X1 is a portable automatic oil dielectric strength tester with output voltage up to 100 kV, featuring automatic voltage ramp, automatic stirring, digital display, automatic printing, and ±3% measurement accuracy - designed for safe, repeatable field and laboratory oil quality assessment. |
