Metal Enclosed Power Factor Correction Units

Power Consultants is a New Zealand manufacturer, supplying power factor correction units for power factor correction and/or voltage support for either low or high voltage systems to various industries and utilities throughout New Zealand and Australasia.

Our High Voltage unit is a packaged reactive compensation system, which combines primary components, and secondary control within a compact enclosure.

The system can either be configured as a switched or fixed capacitor bank. The switch bank can consist of single or multiple steps, automatically controlled to improve power factor or voltage support.

The design, built to customer specification, provides compensation for both large industrial consumers and electrical distribution utilities.
Control Section
The control cubicle can accommodate the following options:
  • Power Factor Controller with relevant communication protocol where required
  • Capacitor Switch operation - PLC Controlled or Zero Volt Closing Controlled(ZVC)
  • Control Relays & Terminals
High Voltage Section
The High Voltage section can, according to the options selected, accommodate the following:
  • Incoming High Voltage supply which is terminated on to copper bus bars
  • Line Current Transformers
  • Connecting busbars
  • High Voltage measuring Voltage Transformers
  • Capacitor HRC Fuses
  • Current Limiting Reactors and/or detuning reactors
  • Capacitors
  • Anti-condensation heaters
  • Cooling fan
  • Thermostat
  • Capacitor Switches
We are making use of Joslyn Capacitor switches, which are specifically manufactured for use as a capacitor switch.
The Joslyn Switches can be applied in two different methods.
The one as a switch, and the other is by making use of the Zero Volt Closing control. Zero Volt Closing Control reduce system over voltages and stress on capacitors due to over voltages and high inrush currents.
This in itself increases the life of the capacitor switch and the capacitor.
