How to Perform Step down Transformer Lamp Repairing

There are manufacturers across the world offering premium transformers repairing services. This post is about repairing the lamp of step down transformer at your own. This project will require the components of the lampbulb, transformer, and base. Apart from this, you will also require a soldering iron, power strip, and a little multipurpose tool used by technicians.

What’s inside the black box?

One of the lacking of the design of transformer lamp is the remote transformer inside a plastic box. The transformer is placed halfway between the ends of a power cord i.e. approx. 6 ft long. Transformer is a heavy component that the manufacturing company might have had a better design with reliable packaging. When the plastic case was unboxed, experts observed:    

Damaged plastic black case Step down coil with magnetic core Fractured output connector Primary side coil hardwired to AC power cord

Steps to Follow: 1. Remove the potting material and access the leads of the primary side coil Electrical component manufacturers rapidly pot their products with non-conductive material. This offers robustness to the product and make it safer for consumer. Electrical devices are built with sensitive components and with potting, manufacturers make them immobilize. This further helps them in making the device more robust and resistant to mechanical shock and abrasion.

High voltages can be a safety hazard, so potting material’s electrical isolation property prevents accidental electrical short circuits that can result in fire incident, fatalities, or injuries.

2. Reconnecting the primary winding leads to the AC power cord This is an additional step included in the troubleshooting process as the soldered connections may have been damaged by first step. Regardless of the time when leads were damaged or distorted, the connections were broken when inspected without potting material across the primary winding.

3. Apply power to the transformer and check proper operation

Output Connector Story Inspection of the lamp’s transformer revealed the damaged done to the output connector. However, when you see from the outside, you won’t find any disorder, but initially the connector has been fractured. This makes transformer unable to perform and function properly. You can hire some technicians if you are unable to perform transformers repairing job your own.
