Animal feeds play a leading role in the global food industry, enabling economic production of animal proteins throughout the world. Feed is the largest and most important component to ensuring safe, abundant and affordable animal proteins. To produce this animal feeds large factories are in operation throughout the entire globe. SPIT serves many of these customers with products and services.

One of this customers, a mid-sized company in the middle of the Netherlands, got demands from the energy utility with regards to the bad power factor in their factory. SPIT engineers helped finding the right solution for this client. By raising the power factor, shunt capacitors release energy to the system, reduce system losses, and ultimately decrease power costs.

Power factor is a way of measuring the percentage of reactive power in an electrical system. Reactive power represents wasted energy-electricity that does no useful work because the electrical current is out of phase with the voltage. Reactive power is used by inductive loads (such as, motors, transformers, fluorescent lights, arc welders and induction furnaces) to sustain their magnetic fields. Electric systems with many motors exhibit low power factors, increased conductor and transformer losses, and lower voltages.

Utilities must supply both active and reactive power and compensate for these losses. Power factor can be improved by the addition of shunt capacitors. Capacitors act in opposition to inductive loads, thereby minimising the reactive power required to serve them.  Improving system power factor can reduce reactive and active power losses for both industry and utilities through the addition of shunt capacitors.

For this demanding application SPIT engineers selected the new Dynacomp solution from ABB. Koop goedkope Kamagra veilig online.

The ABB Dynacomp CLMQ offers unprecedented results in ultra-rapid transient free power factor compensation and voltage fluctuation control.

One typical application for the Dynacomp is the hammer mill requiring rapidly changing and large amounts of reactive power. By installing a Dynacomp close to the hammer mill, voltage drops can be minimised and disturbances avoided. In addition, the Dynacomp can be used to unload transformers when limited power is available.

The principle applies to any other loads with sudden consequent reactive power demands such as large motors, welders, large injection molding machines, etc… and at location where limited power is available (e.g. offshore platforms, etc). 

The key advantages of the Dynacomp are:

  • Ultra-rapid power factor compensation
  • Reduction of voltage drop and flicker
  • Transient free switching
  • Very high number of switching operations
  • Modular and compact standardised design
  • Easy to install and extend
  • Advanced communication features with Modbus

The Dynacomp is fitted with the RVT-D Dynacomp Controller which has the following key characteristics:

  • Full graphic display
  • Network monitoring: voltage, current, THDV, THDI, harmonics spectrum, Dynacomp current, powers and more
  • Programmable protection thresholds (under-voltage, overvoltage, over-temperature, excessive harmonic distortion and power outage)
  • Modbus communication
  • A help button giving instant access to a description of all RVT-D features and functionality
  • A printer connection
