Single-cup, fully automatic insulating oil dielectric strength testing up to 80 kV &100KV optional — compact, portable, and compliant with national and international standards.

The **Portable 80kV (100KV)Insulation Oil BDV Tester** is a microprocessor-controlled instrument designed for automatic measurement of insulating oil breakdown voltage (BDV). With a single-cup design and a compact, portable form factor, it performs the complete test cycle — boosting, maintaining, stirring, standing, calculation, and printing — automatically after simple parameter setup.

Compliant with IEC 60156, ASTM D866, and ASTM D877, this portable oil BDV tester is widely used in power systems, railway systems, and large-scale petrochemical plants for routine insulating oil testing.

Why Choose the Portable 80kV Insulation Oil BDV Tester?

Challenge :Portable 80kV BDV Tester Solution |

Need for on-site oil testing , Compact, portable design (465 × 385 × 425 mm) |

| Data recording and traceability | Stores 100 test results with power-down preservation |

| On-site safety concerns | Over-voltage, over-current, and limit protections built-in |

| Immediate reporting needed | Built-in thermal printer prints each breakdown value and average |

| Temperature/humidity monitoring | Displays current ambient temperature and humidity |

Technical Specifications

Key Functions and Features

– **Fully Automatic Operation** — Microprocessor automatically completes boost, hold, stir, stand, calculation, and printing within 0–80 kV (100KV)range for oil circulation withstand voltage testing.

–

– **Simple Operation** — After simple parameter setup, the instrument automatically completes the withstand voltage test on one cup of oil sample. Breakdown voltage values of 1–6 times and cycle counts are automatically stored. After the test, the thermal printer prints each breakdown voltage value and average.

– **Power-Down Preservation** — Stores up to 100 test results, and displays current ambient temperature and humidity.

– **Uniform Voltage Boost** — Single-chip microcomputer-controlled uniform boost, voltage frequency accurate to 50 Hz, making the whole process easy to control.

– **Comprehensive Protection** — Over-voltage, over-current, and limit protections ensure operator safety.

– **Temperature & Clock Display** — Displays measured temperature and system clock.

– **RS232 Interface** — Standard RS232 for computer communication.
