When Do You Need Power Quality Testing in Coburg? 2026 Safety Guide

You may need Power Quality Testing when lights repeatedly flicker, equipment resets unexpectedly or machinery stops and an initial electrical inspection hasn’t found the cause. By recording voltage and other electrical measurements while your Coburg home or business operates normally, an electrician can check whether changes in the supply line up with the symptoms you’re seeing.

Signs You May Need Power Quality Testing

The pattern matters. If lights in several rooms dim when an air conditioner starts, or multiple machines reset around the same time, write down what happened and which equipment was running. Power Quality Testing can help investigate whether those events coincide with a voltage change. www.powerqualityaustralia.com.au

  • Lights flicker in several areas. Note whether it happens across the property or only in one room.

  • Equipment shuts down or resets. Record which devices were affected and whether they stopped together.

  • Machinery stops at a predictable time. Check whether the timing coincides with equipment starting elsewhere on site.

  • A fault keeps coming back. Note when it happens, particularly if the equipment was working normally during an earlier service visit.

An isolated flicker in one fitting or an error on one appliance may call for a closer look at that fitting or appliance first. If a circuit breaker or safety switch repeatedly trips, have a licensed electrician investigate the trip before deciding whether Power Quality Testing is useful. Energy Safe Victoria

What Power Quality Testing Measures

An electrician can use a power quality analyser to record voltage and current over time. Depending on the issue, Power Quality Testing may look for voltage dips, voltage rises, harmonics or an imbalance between phases on a three-phase supply. The electrician can compare the readings with the times your lights dimmed or equipment stopped.

Picture a Coburg workshop where a machine’s control panel restarts when the compressor kicks in. Power Quality Testing can show whether there was a voltage dip at the monitoring point when the panel restarted. If the timing matches, the electrician has a lead to investigate. If the readings stay steady during the restart, the next check might focus on the machine or its circuit. www.powerqualityaustralia.com.au

In Victoria, the Essential Services Commission’s Electricity Distribution Code of Practice sets out distributors’ supply quality obligations. If Power Quality Testing suggests a possible issue with the incoming supply, the results can help you describe what happened and when you report it to your distributor. esc.vic.gov.au

What to Record Before Power Quality Testing

If there’s no immediate safety concern, keep a short log of what you can observe during normal use. A few entries can help an electrician choose where to monitor and when Power Quality Testing is most likely to capture the issue. Leave the switchboard closed and record the symptoms from a safe position.

  1. Write down the date, time and duration. Even an approximate time can help match an event to the recorded data.

  2. List what was affected. Include the rooms, lights or machines involved and whether they were affected together.

  3. Note what else was running. Record whether a compressor, motor or air conditioner had just started.

  4. Save any equipment error messages. A photo of the display or a copy of the fault log can help an electrician compare events.

If the problem tends to happen during a particular shift or production cycle, share that schedule before Power Quality Testing starts. For example, if a machine only resets during the first run on Monday, a monitoring period that misses that run may miss the event you’re trying to capture. megavar.com.au

When to Call a Professional

If you notice dim or flickering lights, low voltage or partial supply after an outage, Energy Safe Victoria advises contacting your electricity distributor immediately and avoiding contact with your switchboard or metal objects in your home. Treat this as an immediate supply concern. Power Quality Testing can be considered later if the issue persists and needs investigation. Energy Safe Victoria

For a recurring issue at your Coburg home or business, contact EES Electrics and describe what happens, how often it occurs and what checks have already been done. Ask whether an initial fault-finding visit or Power Quality Testing is the right next step.

Conclusion

Power Quality Testing is useful when an electrical problem comes and goes and you need to find out whether a change in supply coincides with it. Start with a record of what happened and which equipment was affected. If the fault keeps interrupting your home or business, ask EES Electrics about the next step for your Coburg property.

Frequently Asked Questions

How long does Power Quality Testing take?

The monitoring period depends on how often the fault occurs. If it happens every morning, the electrician can plan around that window. A fault that occurs less often may need a longer recording period.

Can Power Quality Testing tell me whether the issue is inside my property?

It can help narrow down where to look. An electrician may compare readings at different points or check whether disturbances coincide with equipment starting on site. Further checks may be needed to confirm the source.

Can Power Quality Testing help if my solar inverter keeps disconnecting?

It can help check whether voltage changes coincide with the inverter disconnecting. Share the inverter’s error codes and event times with your electrician so they can compare the logs with the measurements.
