Troubleshooting

[Adrian Francis]

Good day, have a questions to ask u.

You are working in an industry as a Maintenance electrician, you receive an email from your supervisor that there is on electrical issue at the main Building. It issues relates to high Voltage, where small load equipment is working and high load equipment r not working. The Main Breaker trips periodically.

How you Would approach this?
And How solve this problem?

Make arrangements with the building owner to shut down the power first.

Step 1, gather all of the real information first hand, not what someone tells someone else, who tells someone else, who tells you.
Step 2, determine if YOU are qualified to deal with it, i.e. if you have the right skillset and have had proper safety training on whatever voltage level is involved. If not, you let them know they need to call someone else who is qualified.

What is the voltage? Alarm installers refer to 120 as high voltage.

Sounds like an overload on the "high load equipment." Not an electrical fault, but a mechanical problem like a jammed conveyor or bad pump bearings. Find out which piece of high load equipment is drawing too many amps and go from there.

When a breaker trips, it's either because the current actually exceeded the breaker's rating, or because it tripped for another reason, such as excess internal or eternal heat, or the breaker's mechanism is faulty.

Your job is to determine why it's tripping. I would first look for heat generation and contact and termination integrity. You can measure/monitor the current over time to see if the breaker is simply doing its job.
