BDV Testing: Ensuring Transformer Oil Quality with GlobeCore’s TOR

In the electrical power industry, the reliability and safety of transformers are paramount. One critical aspect of transformer maintenance is assessing the insulating properties of transformer oil through BDV testing (Breakdown Voltage Testing). GlobeCore, a leading manufacturer of industrial equipment, offers the TOR-60 unit—an advanced solution designed to accurately measure the dielectric strength of transformer oil and other dielectric fluids in accordance with international standards.

BDV Testing

BDV testing involves measuring the breakdown voltage of insulating oils used in transformers. The breakdown voltage is the minimum voltage that causes a portion of an insulator to become electrically conductive. This test is essential because:

• Assessing Insulation Quality: Determines the oil’s ability to withstand electrical stress without failure.
• Detecting Contamination: Identifies the presence of moisture, particulates, and other contaminants that reduce dielectric strength.
• Preventing Failures: Early detection of degraded oil prevents transformer breakdowns and extends equipment life.
• Ensuring Compliance: Meets regulatory standards and safety requirements for transformer operation.

The BDV Testing Process with TOR-60

1. Sample Preparation: Collect a representative oil sample from the transformer, ensuring it is free from external contaminants.
2. Setting Up the TOR-60: Place the oil sample in the test cell and configure the testing parameters via the user interface or connected software.
3. Automated Testing: Initiate the test; the TOR-60 automatically increases the voltage until breakdown occurs.
4. Instantaneous Disconnection: Upon breakdown, the unit disconnects the voltage within 4 μs, preserving the integrity of the equipment.
5. Result Analysis: The TOR-60 records the breakdown voltage and provides detailed results, which can be stored, printed, or transferred for further analysis.

Importance of Regular BDV Testing

Regular BDV testing with reliable equipment like the TOR-60 is crucial for:

• Preventive Maintenance: Identifies degradation in oil quality before it leads to transformer failure.
