A Proactive Approach to Keep Equipment Cool this Summer

Excessive heat can cause equipment to operate outside its designed temperature limits. When the temperature spikes, the components naturally work harder and can wear out quickly.

Pay close attention to:

  • The display on your electrical system to see if it is operating at optimum capacity, especially as the day goes on. A stressed unit can be dangerous for the operator and anyone around the electrical systems.
  • Temperature fluctuations, seasonal weather changes, or even a location near heat producing equipment can adversely affect electrical components causing overheating and failure.

Facility managers that get ahead, thus staying on top of facility maintenance for these important systems will avoid costly expenditures and maximize their facility’s uptime. Expanse offers comprehensive preventative maintenance solutions to keep your equipment operating at optimum conditions.

Prolonged exposure to excessive heat can:

  • Reduce the operating life of electronic hardware
  • Require derating of power supplies
  • Change circuit protection performance
  • Contribute to overload conditions

Remote Monitoring of Electrical Systems

Add an Asset Monitoring System

The asset monitoring systems of today go far beyond traditional monitoring via SCADA systems. These systems include edge computing platforms with machine learning algorithms, web-accessible dashboards, and conditioning monitoring services. Expanse’s solutions include AI-based analytics with predictive maintenance, providing new avenues for early event detection that enable facilities to take corrective actions.

Asset monitoring systems comprise of:

  • Power monitoring
  • Operational Information
  • Condition monitoring
  • Equipment lifecycle monitoring
  • Predictive analytics
  • Event detection and notifications
  • Site dispatch

Conduct Summer Preventative Maintenance

It is recommended you establish a complete preventative maintenance plan to prep your equipment for the summer heat. Expanse offers a detailed scope and interval for maintenance and the testing of electrical equipment following the guidelines found in ANSI Maintenance Standards, NFPA 70B, and NFPA 70E.

Typical equipment requiring testing and maintenance:

  • Medium Voltage motor controls
  • Low Voltage motor controls
  • Variable frequency drives
  • Battery chargers
  • UPS systems
  • Medium voltage transformers
  • Switchgear
substation testing

Utilize Thermal Management

The effects of solar radiation on control panels can cause the internal temperature to rise dramatically. Controlling the temperature can eliminate the risk of condensation forming inside the enclosure and eliminate overheating of the electrical devices. Expanse utilizes different types of thermal management systems to maintain optimal environmental conditions inside control enclosures.

Controlling the temperature can:

  • Eliminate the risk of condensation forming inside the enclosure
  • Eliminate overheating of the electrical devices
  • Help account for solar heat gain
  • Decrease solar heat gain

Ensure Proper Air Flow

Without proper air flow the enclosure can turn into a hot box, trapping the heat. Clear and debris-free air passages in cooling systems provide efficient exchange of outside air.

When dust gets into electrical equipment regardless of the type of equipment such as motor starters, motor control centers, switchgear, dry-type transformers or enclosed circuit breakers two potential outcomes could occur:

  • An inability to allow normal convection cooling as the dust inhibits needed airflow to prevent equipment overheating.
  • A short circuit or an arc flash incident could occur as dust could be conductive and cause a flash across bus bars or phases.

Cooling systems required to operate in dusty and corrosive environments will require a regularly scheduled maintenance program. Ignoring maintenance can lead to blocked filters and condenser coils causing not only electrical component failure but also damage to the cooling systems resulting in voided warranties. In these cases, significant downtime could end up being the result which costs far more than the cost of preventative maintenance.

Cooling systems maintenance program includes:

  • Air filter cleaning or replacement
  • Condenser coils and fan blades dust accumulation inspection
  • Excessive dust, dirt, debris buildup removal
  • Air intake and exhaust routes obstruction removal
