Dry-Type Transformer Upgrade for an Electronics Plant

Project Background

A large electronics manufacturing site had recurring line trips during peak shifts. The existing transformers had high heat rise and unstable voltage under variable-frequency motor loads, causing process interruptions and scrap risk.

Solution

The customer adopted new SCB-series dry-type transformers near key production zones and rebalanced feeder allocation:

• Replaced legacy units with low-loss, low-noise dry-type models.
• Added temperature monitoring and alarm integration to the plant BMS.
• Reconfigured cable routing to reduce distribution distance and voltage drop.

Results

Within three months of commissioning, the plant reported:

• About 18% reduction in unplanned power-related stoppages.
• Improved voltage stability for SMT and testing lines.
• Lower routine maintenance workload due to oil-free design.

Key Takeaway

For high-value manufacturing, a dry-type transformer upgrade can deliver both reliability and operational consistency, especially when paired with monitoring and feeder optimization.
