Elspec Active Industries

Welding Machines

Spot welding loads fluctuate extremely rapidly and consume large amounts of reactive power. Due to high current changes caused by the near-instantaneous reactive energy consumption, large voltage drops are produced. These sags reduce weld quality and decrease welding productivity. Additionally, these loads often create a high incidence of voltage flickering, which frequently exceeds weldong-machinesrecommended IEEE limits. Elspec’s real-time EQUALIZER benefits:

  • Improve Welding Quality & Reduce Scrap/Reprocessing
  • Increase Production Output
  • Reduce Voltage Flickering
  • Stabilize the Network Voltage
  • Optimize the Use of your Existing Power Structure
  • Reduce Maintenance Costs


Plastic Injection Moulding

plastic injection moulding

Due to widely varying unsynchronized load conditions, plastic injection moulding applications have rapid & inconsistent reactive energy requirements. Power supply failure during a production cycle can cause enormous financial and physical damage caused by plastic cooling inside the machines. Besides reducing overall system energy losses, Elspec’s EQUALIZER solution drastically reduces the risk for such an event by stabilizing the current and voltage levels in the facility on a cycle-by-cycle basis

  • Reduce Clean-up Costs, Raw Material Losses & Loss of Production
  • Improve Consistency & Quality of Product
  • Avoid Plastic Cooling Inside Machinery
  • Stabilize Voltage & Current Levels Cycle-X-Cycle

Harbour Cranes

The complete operation cycle of harbour cranes is approximately one minute. During this time, the crane requires variable amounts of reactive energy, fluctuating rapidly throughout the entire crane cycle. The Elspec EQUALIZER’s real-time solution:

  • Stabilize Voltage Fluctuations
  • Reduce Currents
  • Smaller Service Installations (Less Cable = Reduced Heat)
  • Reduce System Losses
  • Save Energy

Electric Trains

Electric rail lines have long power distribution systems and rapid load changes, leading to substantial voltage drops and voltage flickering. The Elspec EQUALIZER system

  • Provide Voltage Support to the Distribution Network
  • Stabilize Network Power
  • Compensate for Both Inductive & Capacitive Loads
  • Prevent Low Power Factor Penalties
  • Minimize System Losses & Maintenance Costs
  • Increase Network Loading Capabilities

Hospitals, High-rises and Other Commercial Buildings

hospitalsMost commercial buildings have significant load variations caused by elevators, air conditioning equipment and other rapidly changing loads. Further, today’s medical equipment, computers and other sensitive loads can be damaged by spikes caused by conventional capacitor systems.


  • Stabilize the Facility Load
  • Eliminates Spikes caused by capacitor switching
  • Highly Reliable System – High MTBF Value & Maintenance-Free
  • Increase Life Expectancy of Sensitive Equipment
  • Reduce Maintenance Costs
  • Increases available power for new loads on existing infrastructure

Wind Energy

Wind turbine generators have become a significant contributor to power generation throughout the world. As a result, utility regulations for wind turbines have become more constrained, and now require stable voltage, reactive energy supply to the network and voltage control to support network failures. The Elspec EQUALIZER-W is specifically engineered for the wind energy market, and features communication protocols that match its controller to the algorithms of leading wind turbine manufacturers worldwide

Motor Start-up

Typically demands during motor start-up activities, create reactive currents that are 3-8 times of the motor’s nominal current during a very short time period. Effective reactive compensation needs to occur not only during start-up period, but during steady-state period as well.

motor start-up

When connected directly to the line, large squirrel-case inductive motors consume very high current during the start-up period (six times higher than steady state operation). This high current consumption can lead to significant voltage drops on both the low and high voltage sides of the transformer, which interfere with other loads, reduce initial torque and increase start-up time. The EQUALIZER system tracks the reactive current and fully compensates it in 2/3 cycle typical, offering the following benefits:

  • Protection against voltage drop on the main service
  • Capability to central-start all loads, avoiding the use of individual starters commonly used to protect against voltage drop
  • Direct connection of motors to main service, obtaining maximum torque during start-ups. This benefit is unique to the EQUALIZER solution, as starters of all types typically reduce the current going through the motor, thereby reducing the starting torque.

Mines & Mineral Processing

The Mineral & Mining Industry faces enormous challenges in today’s economy. One of the biggest obstacles is the effective management of operating expenses. Therefore, the reduction in energy costs takes the highest priority in securing, maintaining & building a sustainable business.

Most facilities are located in rural areas, making them susceptible to a lower quality in their power supply. As a consequence, this severely constrains production & impedes their ability to achieve their intended business objectives. Another contributing factor, is the industry’s dependence on large loads. Mills, conveyers & pumps are powered by high capacity electric motors that are heavily reliant on a constant & good power supply.
