Grommet Strip - (GS) - PVC Beading strip is used to protect cables routed through sharp-edged cut-out sections. It can also be used to provide an attractive finish to panel edges. Manufactured to high standards using flexible PVC compound.

Terminals - (Copper Tube) – All types manufactured from electrolytic copper tube. The terminals are designed to obtain the most efficient electrical conductivity and mechanical strength to resist vibration pull out.

Cable Markers - (PA) – Secure identification marker sleeves for unconnected wires and cables. Designed to interlock when fitted, enabling easy alignment of multiple character markings.

Contactors - (UA) - Contactors used in the automatic panels are specifically designed for capacitive loads, and for this reason are provided with pre-insertion resistors and reinforced special contacts. Contactors must be sized according to the rating of the capacitor bank it’s switching and the...

Fuses - (NH) - Fuses with top and combination indicator are available in a large variety of voltage ratings, body sizes and operating classes. Only use superior quality fuses for cooler running and efficiency when installed with capacitors.

Thermostats - (KT) - Ensure components are operating within their approved temperature range by maintaining the minimum and maximum conditions within cabinets. These DIN rail mountable thermostats have control ranges of -10 to +60 degrees °C and can be used with heaters or fans.

PFC Electric offers a full range of three phase power transformers. These can be manufactured to order in days, not weeks and we do stock many standard three phase transformers.
Transformers can be supplied as open style or in enclosures to IP23 through to IP65. Some applications are for isolatio...

Our Tri-rated H07V2-K cable has been designed for the internal wiring of electrical cabinets, switchboards and small electrical devices. Due to its manufacturing characteristics, it can be used in conduit or in flexible motor ducts, transformers and other machinery in general

t’s recommended that Power Factor Correction is serviced annually. PFC Electric will complete a test report which includes environment, loading and suitability checks to accommodate changes in supply. They will also interrogate the relay to determine the number of operations attributed to each ca...

Power Factor Correction

  • Power Factor Correction Site Service With Test Report

    Regular servicing of power factor correction equipment ensures that the rated output is maintained. When failure occurs no apparent warning is given and faults may go undetected for quite some time. Digital controllers continue operate and contactors will still switch in and out, but the capacitors may not be fully operational. Most modern capacitors incorporate fail-safe protection mechanisms which quietly disconnect them so again failure goes undetected. A faulty capacitor bank can cause a multitude of supply problems and monthly savings could be compromised.

What is Power Factor Correction?

Power factor correction is a technique of increasing the power factor of a power supply. Power supplies without power factor correction draw current in short, high-magnitude pulses. These pulses can be smoothed out by using active or passive techniques and this reduces the input RMS current and apparent input power, thereby increasing the power factor. The power factor correction shapes the input current in order to maximize the real power from the AC supply. Ideally, electrical equipment should present with a load that emulates a pure resistor, meaning that the reactive power would be zero. The current and voltage waveforms would be the same sine wave and in phase with one another. However, due to the reactive components in a majority of circuits, there is always a power lag that leads to lower poor power factor. In an ideal system, all the power drawn from the AC mains is utilized in doing useful work, this is only possible when the current is in phase with the voltage. When the phase between the two varies, some of the energy from the AC outlet does not perform useful work and is lost. The power generating company must therefore produce more power to meet the demand for the useful power and the one that is lost. This means more capital investments in generation, transmission, distribution and control. The costs are passed on to the consumer in addition to contributing to global warming. Power factor correction tries to push the power factor of the electrical system such as the power supply towards 1, and even though it doesn’t reach this it gets to as close as 0.95 which is acceptable for most applications.
