PFC Maintenence FAQs
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:
- Microfarad test of the capacitors to check kVAr output
- Insulation resistance of power cables
- Manual function tests of contactors
- Fuse checks
- Full physical tightness check of all terminals
- Full clean out of equipment cubicle and vents
- Full function tests of control relay
- Check the operation of Fans and quality of filter elements
- Site Load survey
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 maintenance?
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.
Power Factor Correction FAQs
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.
Power Quality Health Check FAQs
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.
What’s 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.
Surge Protection FAQs
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.
