Troubleshooting Potential Causes1. Surge Protection

Verify that all computers and phone equipment are properly connected to surge protectors. Faulty or outdated surge protectors could allow power surges to damage devices.2.

Power Supply Units (PSUs)

Check the PSUs of the affected computers. Failing or underpowered PSUs can cause power-related issues.3.

Electrical Wiring and Circuitry

While the electrician and utility company may have found no obvious problems, it's possible that there could be intermittent issues or hidden wiring faults that are causing the problems.4.

Office Equipment Cross-Interference

Certain office equipment, such as refrigerators, microwaves, or copiers, can generate electrical noise that can interfere with sensitive electronic devices. Try isolating the affected equipment from potential noise sources.5.

Grounding Issues

Inadequate grounding can lead to power-related problems. Check that all electrical outlets and grounding points are securely connected.

Recommended Steps1. Call a Different Electrician

Consider hiring a different electrician who specializes in troubleshooting electrical issues in commercial buildings. They may have more experience with complex wiring systems and be able to identify hidden problems.2.

Check Surge Protectors and PSUs

Replace any faulty or outdated surge protectors and consider upgrading the PSUs of affected computers if necessary.3.

Isolate Potential Interference Sources

Disconnect non-essential office equipment, such as refrigerators or copiers, to see if the problems persist.4.

Consider a Power Quality Audit

Hire a qualified power quality specialist to conduct a thorough audit of the electrical system and identify any potential issues that may be causing the interruptions.5.

Document the Problem: Keep a detailed record of the problems encountered, including the dates, times, and equipment affected. This information can be valuable for troubleshooting purposes and for reporting to the utility or electrician. Flag for review
