What is Power Factor Correction?
Power Factor (Cos φ) is the ratio of True Power (kW) to Apparent Power (kVA) and is used as an indication of how efficiently an industrial or commercial site is operating. The closer the Power Factor is to unity (1), the more efficiently a site is said to be operating.
Can Power Factor Correction Save Me Money?
Yes! Reducing your sites Power Factor will in turn reduce the amount of Reactive Charge you maybe being billed for on your monthly electricity statement.
Whats checks are carried out during a PFC Maintenance?
During a annual service of your Power Factor Equipment some of the main tests we carry out are:
Other additional tests may be carried out depending on the type of PFC installed on site
How much does it cost to carry out a PFC Maintenace?
The cost to carry out a full Power Factor maintenance will vairy from site to site depending on the total number of PFC units on site as well as the total amount of kVAr. We can provide quotations for individual customers based upon theses factors and our office team are happy to assist with any further questions regarding pricing.
What is a Active Harmonic Filter?
An active filter is basically an inverter based harmonic current source that measures the magnitude and phase of the load current harmonics. The AHF injects compensation current that are the exact opposite to cancel out the load behaviour.
Can a filter be installed into my existing mains panel?
Yes, subject to available space, the AHF components can be custom built into any existing panels on site in a ‘plug & play’ style installation.
What kind of Active Harmonic Filter do I need?
AHFs come in a variety of output sizes and a full site survey and analysis will need to be carried out prior to any new installation. This can be carried out by PFC Engineering Ltd and on completion we will provide you with a full detailed site loading report along with any recommendation and quotations required.
Why should we have a Power Quality Health Check?
Having an annual or bi-annual power quality health check provides the potential to prevent costly power issues that might arise from things such as installation of new equipment or site expansion.
Whats involved in a Power Quality Health Check?
An initial site survey is required to evaluate the makeup of the site, this can be done over the phone or in person at site. Following this a engineer will visit site to connect a power analyser to the LV supply which will be left of a minimum of one week where upon it will be collected and the data reviewed. This will be followed up with a full report and any recommendations.
What is Surge Protection for?
Surge protection devices are used to protect sensitive electrical equipment such as computers and control equipment from potentially damaging voltage transients.
How do I know if my Surge Protection is working?
This does vary depending on the make of surge protection installed but the SPD will usually have some form of indicator for each phase. This is usually a colour tab or indicator light showing if the phase is healthy or has reduced protection. Most SPDs will have instructions regarding this printed on the front of the equipment, however if in doubt feel free to contact us and we will be able to assist in identifying any failures.
Can I connect my metering to my BMS System?
Yes! The Raleigh RF metering cube can come with a variety of connection options so that it can communicate with your sites BMS.
Can I remote monitor my electrical meters?
With the addition of Go Monitors gateway system, multiple meters can be connected to a single online IoT portal, providing a dashboard visualisation customised for your needs.
Can I replace my old Volt & Ammeters with a digital meter?
Yes, we can use sites existing meter connections to install a digital meter and in most cases this work can be carried out normal working hours without disruption to site.
How does Voltage Optimisation work?
The basic idea behind most forms of voltage optimisation is to reduce the incoming supply voltage from a level provided by the grid to one that is more suited to the needs of the equipment on site.
What are the main benefits of Voltage Optimisation?
The main benefit form installing VO is site can save up to 15% of their energy consumption ultimately saving you money on your electricity bill as well as extending the life expectancy of other equipment on site.
