Transformers are helpful devices used in construction that essentially reduce or increase the voltage of an alternating current. Since these devices are designed for high-voltage purposes, you need to observe the following safety protocol.
Keep Transformers Grounded
When a transformer is not grounded, stray charges can spread that builds up over time. Too much charge and you could do serious harm to equipment on the construction site, or worse, do harm to nearby construction workers.
Basic transformer grounding requires a stable electrical path that's designed for ground-fault conditions. The path also needs to have the correct electrical carrying capacity because otherwise, you risk electrical shock and severe equipment damage as currents try to find a suitable point of navigation.
If your transformers are not grounded adequately or at all, consult with the appropriate service right away to ensure overall safety for workers onsite.
Be Aware of Moisture and Water
Transformers carry a tremendous amount of voltage, and the slightest drip of water could result in a severe accident. As such, you need to keep the transformer and components around it completely dry. Avoid bringing water bottles and other beverages near these high-voltage areas, at least while the transformer is active.
If there are new workers on the job site, you may want to set up warning signs stressing the importance of a dry work zone. There are plenty of other ways to prevent moisture too, such as ensuring that the main tank is properly sealed. You'll also want to repair any oil leaks that occur around the body of the transformer.
Perform Regular Inspections
Even if the transformers you're working on are relatively new, they still need a thorough inspection a couple of times a year. These inspections can be carried out safely and efficiently when you use a professional service.
A professional will come out and check the transformer's power cords, connectors, tank, and other integral parts. If any part needs to be replaced, whether it's because of wear and tear or leaks, they'll provide an in-depth evaluation beforehand. Even parts that are in good condition can be checked to make sure they were properly installed.
Construction sites are naturally dangerous, especially if there are transformers near the vicinity. Fortunately, you can maximize safety by working with pole mounted transformers in a controlled, well-researched manner. The more you know about these machines, the less risk you take on when working with them.
