Power Quality Solutions for Warehousing & Logistics

The skyrocketing demand for data centers is driven by the exponential growth of data for A.I., IoT, cloud storage, data analytics, security, communications, and digital currency. The cooling centers used within these centers are critical to maintaining proper operating temperatures. On average, cooling represents 40% of a data center’s energy consumption. In order to reduce costs, companies drive better cooling efficiencies through the use of Variable Frequency Drives (VFDs) on the chillers, cooling towers, and electronically controlled (EC) fans and motors. As the demand for VFDs rises, so do the power quality issues. MTE power quality solutions ensure maximum obtainable efficiencies are achieved, less stress on the utility is created, and the lifespan of motors are greatly increased.

Modern warehouse and logistics centers have increased complexity and harmonic issues

  • The motor control cabinet inside a facility provides integrated, precision control, but it’s also the leading cause of unwanted harmonics.
  • Stray voltages can cause strain, overheating, and damage to gear box motors.
  • Conveyor belt motors are often located 1,000 ft. or more from the drive unit, leading to heavy distortion from harmonics.
  • Electrical “pollution” can damage the sorters and lifters found on conveyance systems.
  • The increased use of battery powered forklifts and robotics require additional charging stations which ultimately drive up your facility’s harmonics.

Power Quality Challenges for Warehousing and Logistics

Warehouse facilities face a variety of power quality challenges, from both the line side and load side of the VFD. On the line side, unwanted harmonic loads throughout the system can lead to costly utility violations or nuisance tripping, while the harmonics generated on the load side often lead to premature motor and cable failure or motor bearing damage.

In addition, more facilities are using autonomous robots as part of their daily operations. While effective, the charging stations needed to recharge the robots throughout the day, can also create their own harmonics, which can adversely affect transformers.

Any and all of these challenges can lead to unexpected replacement expenditures and costly production downtime within your facility.

Unplanned Downtime

Motor and gearbox failures can result in numerous hours of maintenance, idled workers, and potential safety concerns.

Utility Compliance

IEEE-519 compliance is critical for industries to remain in accordance with local regulations.

Maintenance Staffing

Availability of specialized personnel during peak hours can be challenging, further extending downtime costs.

Damaged Shipments

Sudden stops or failures in sorting or conveyance can cause damage to valuable shipments, resulting in additional recuperation costs.
