While utilizing equipment which emits a constant voltage source, similar to the way some transformers do, it’s essential to take safety precautions into consideration. As safety precautions aren’t met, emergency shutdown, system breakdown, and injury may result, each of which may put your operations in jeopardy.
Knowing your transformer’s proper installation and design ensures successful machinery operation. These transformer safety practices may be used in any transformer machinery piece, independent from the system or manufacturer type.
Top Ten Transformer Safety Tips
1. Observe your transformer prior to it being installed, assessing for any burning odor, unsuitable or cracked plugs or power cords, and misaligned or loose parts.
2. Routinely check the transformer to minimize breakdown or system failure.
3. As any work is done on the transformer, it must be performed as the equipment is tagged out, de-energized, and the circuit must be shut down. There shouldn’t be any continuity or electrical leakage between the house current and your system.
4. Stay careful of system overloading. Several transformers must be utilized in place of having a single transformer.
5. A person who is working with transformers must be utilizing protection equipment especially rated for the voltage output of the transformer.
6. Don’t change a transformer’s overcurrent protection of circuits and conductors to raise the permitted current. Overcurrent protection must be maintained at the right level per equipment standards.
7. You should always make sure that the transformer is grounded. Transformer grounding will remove all static charges that might otherwise accumulate. Also, grounding will protect the windings from contacting the core or enclosure.
8. Make certain that you note that control circuit power sources still will be on even after equipment interlocks disconnect.
9. Be certain no spare tools, nuts, bolts, or foreign objects of any type fall into or onto the transformer.
10. Never utilize the transformer in wet areas or spaces in which there is water present.
