6. Installation and Maintenance

Installation

• Base Fixing: During installation, the transformer must first be fixed on a solid base to ensure levelness.
• Wiring: Connect the primary high-voltage cable and the secondary low-voltage cable, ensuring strict insulation separation between the primary and secondary sides.
• Grounding: Effective grounding must be carried out to prevent hazards caused by electromagnetic induction.

Maintenance

• Oil-Immersed Maintenance: Regularly check the oil level and oil quality, conduct oil sample analysis, and detect impurities and moisture in the oil.
• Dry-Type Maintenance: Regularly check the insulation performance to ensure no dust accumulation.
• Regular Inspection: Regularly conduct electrical tests (such as DC resistance test, dielectric loss test) and temperature detection of the transformer to prevent faults.
