What is the difference between dry-type and oil-type transformers?

Dry-type transformers use air as the cooling medium, while oil-filled transformers use oil instead of air.

How do I clean and maintain these control transformers?

• Ensure safety by disconnecting the power supply to the control transformers.
• Inspect for any visible dirt, dust, or debris on the transformer surfaces.
• Use a soft brush or compressed air to remove loose particles from the transformer components.
• Wipe the surfaces with a dry or slightly dampened cloth to remove remaining dirt or contaminants.
• Check for any signs of overheating, discoloration, or unusual smells, indicating potential issues.
• Tighten any loose connections or terminals on the transformer to ensure proper electrical conductivity.
• Inspect the transformer for signs of wear, corrosion, or damage and address any issues accordingly.

When should I replace these control transformers?

• Replace control transformers with visible physical damage.
• If transformers consistently exhibit signs of overheating, consider replacement.
• Replace if transformers frequently fail or provide inconsistent power output.
• Upgrade if transformers use outdated technology or do not meet current efficiency standards.
• Replace transformers with significant corrosion affecting performance and reliability.
• If transformers have surpassed their expected lifespan, consider replacement to prevent unexpected failures.
