Safety Practices In Handling Capacitors

Working with capacitors, especially high-voltage ceramic capacitors, as well as Doorknob Capacitors that could be found always, require you to be mindful of certain practices. This is because if you don’t properly handle these capacitors, chances are, you’d end up facing the risk of injury. If you are working with capacitors having 10 joules worth of energy or more, then you should take all the more precaution. Here are the following things to keep in mind when handling capacitors.

Before Operating

First know the status of the work area. Has the capacitor been charged? Has the area been surrounded by a barrier to protect the unqualified from going near the place? Do the workers know the procedures that have been established to bypass and restore safety interlocks? Has the log of events been checked? Are the necessary apparel to safely handle these electrical devices already worn?

On Handling Capacitors

Always check the device grounding, and use only the approved shorting sticks to de-energize the capacitor. In re-energizing, make sure to take out all shorts and grounds, and while servicing, maintain these two.  Verify using all means possible on the device safety. Never proceed to any of these aforementioned steps if you have not been through the standard safety protocol.

Additional Requirements

Before de-energizing, make it a point to measure the voltage prior to grounding and shorting the device. Make sure that you have received and/or given proper training to the workers assigned for this particular task. For new designs, safety features for maintenance as well as personnel for troubleshooting should be mindful of things. To make things easier, it would be best to have permanent indicators situated near the capacitor to check on whether or not the capacitor is charged, to make things more convenient.
