How a Structured Electrical Maintenance Program Improved Food Production Plant Reliability

For maintenance managers and plant managers, the goal is simple: keep production running. Downtime means lost output and unnecessary pressure on teams trying to keep operations moving. Electrical failures are one of the most common causes of unplanned downtime in industrial electrical environments. While many sites respond to breakdowns as they happen, a proactive maintenance strategy can reduce the risk of production interruptions.

At CW Elec Automation, our team of electrical contractors in Melbourne recently implemented a structured preventative electrical maintenance program for a large Melbourne food production facility. The site was experiencing intermittent electrical issues that were disrupting operations and affecting production efficiency. To address this, we introduced a preventative maintenance program designed specifically around the plant’s production schedule. Regular maintenance windows were established on Sundays, allowing electrical systems to be inspected, tested and maintained without interfering with weekday production.

Within just three months, the site saw a 17% reduction in electrical breakdowns and an 8% increase in overall plant productivity. Here’s how a proactive approach to electrical maintenance helped protect production output and improve operational reliability.

Identifying and Solving Hidden Electrical Risks

One of the first issues identified during our inspections was moisture building up inside several electrical cabinets. Temperature fluctuations when machinery was switched was resulting in condensation forming inside electrical boards – a common issue in industrial environments that can lead to corrosion and unexpected shutdowns.

To resolve this, we implemented the following solutions to reduce the conditions that cause condensation and moisture-related faults:

• Installation of moisture-absorbing gel packs inside electrical enclosures
• Installation of cabinet heaters in selected boards to maintain a stable internal temperature when equipment is powered down

Using Thermal Imaging to Detect Problems Before They Cause Downtime

Another key element of our maintenance program was implementing thermal imaging inspections across the plant as part of our ongoing electrical maintenance services. Thermal imaging allows electrical components and connections to be inspected while equipment is running, identifying abnormal heat signatures that may indicate loose connections or failing components. Detecting these issues early means repairs can be scheduled during planned maintenance periods rather than after a breakdown has already disrupted production. For facilities running continuous production schedules, this proactive approach can dramatically reduce unplanned downtime.

Improving Reliability Through Automation and Control System Maintenance

Preventative maintenance doesn’t stop at hardware, as control systems and automation infrastructure also play a critical role in plant reliability. As part of our ongoing maintenance program for this facility, we implemented initiatives to strengthen system reliability, including:

• Uploading and backing up PLC programs to ensure system recovery is possible in the event of component failure
• Making program modifications to improve machine efficiency and operational consistency
• Reviewing control systems to identify opportunities for performance improvements

Maintaining Safety While Improving Production Performance

Safety is an important component of any industrial maintenance program. Through our partnership with this facility, we’ve completed upgrades to safety guards and installed additional safety devices on machinery to ensure the plant maintains a high level of operational safety. This work is particularly important in facilities that include compliance requirements for hazardous areas electrical installations. For maintenance managers, balancing production performance with workplace safety is essential, and preventative maintenance programs help support both objectives.

Rapid Response Support to Minimise Downtime

While preventative maintenance significantly reduces the risk of breakdowns, rapid response capability remains important in any production environment. For this facility, CW Elec Automation provides a qualified industrial electrician on site 24/7 to respond to electrical faults fast. Having immediate access to experienced electrical contractors in Melbourne ensures that any issues that do arise can be resolved quickly, minimising disruption to production.

The Results: Reduced Breakdowns and Higher Productivity

Since implementing this structured maintenance program, the results have been significant. Over a three-month sample period, the facility recorded:

• A 17% reduction in electrical breakdowns
• An 8% increase in overall plant productivity

Through the reduction of electrical disruptions, the plant has been able to maintain more consistent production output and improve efficiency. This has also allowed the client to further expand their maintenance program, reinvesting in additional preventative initiatives.
