HZJQ-1 Transformer Oil BDV Test Kit 80kV 100kV
HZJQ-1 Transformer Oil BDV Test Kit 80kV 100kV
Summary
The HZJQ-1 transformer oil BDV test kit is a high-precision, all-digital industrial instrument developed by our scientific and technical team. Leveraging our expertise and conducting extensive field tests with long-term, unremitting efforts, we have designed this instrument in accordance with the relevant provisions of national standard GB 507-1986, industrial standard DL/T 846.7-2004, as well as ASTM D1816 and ASTM D877.
To meet the diverse needs of users, this series of instruments is available in multiple configurations, including single-cup, three-cup, and cup-type models. The instrument features a simple structure and an elegant appearance.
Features
Extended 100kV Range: Covers the full spectrum of insulating oil test requirements - from routine distribution transformer maintenance (typically 30–60kV) to acceptance testing of EHV transformer oil where standards call for 100kV withstand verification.
Fully Automated Workflow: Boosting → stirring → standing → breakdown detection → calculation → printing are all executed automatically after a single parameter setup, eliminating operator variability and reducing test time by up to 70% compared to manual ramp methods.
Built-In Safety: Over-voltage, over-current, and limit protection circuits safeguard the operator during every test. High-voltage energizes only when the oil cup cover is fully closed.
Field-Ready Documentation: The integrated thermal printer produces an immediate hardcopy of each individual breakdown value and the calculated average - ready for maintenance records, audit trails, and customer reports.

FAQ
Q1: 100kV vs standard 80kV BDV testers? 100kV covers EHV oil, esters, 100kV protocols.
Q2: How many breakdown tests per sample? Average? 1–6 tests; auto mean. 6 per IEC 60156.
Q3: How to clean the oil cup? Silk cloth, 2.5mm gap, ether×3, sample rinse.
Q4: No breakdown at maximum voltage? Display ">100kV". Re-check gap, clean, sample.
Q5: Common faults and how to fix them? Check power, connectors, contrast, printer cables.
