When planning power factor correction, we help the customers with choosing a functional and safe solution at a reasonable cost.
ELECTRICITY BILL ANALYSIS
TKF’s electricity bill analysis is an effective way to determine the necessity for power factor correction (PFC). A preliminary analysis can be made by examining the electricity bills themselves or by requesting the past year’s consumption data from the electricity company. In particular, in the case of consumption data with a reactive power input or output, it is worth sending this data to a TKF specialist for an electricity consumption analysis. Based on this analysis, we determine whether the power factor correction is in order or suggest suitable PFC equipment or further analysis. For more accurate power quality reports, a power factor correction mapping or power quality measurements are required.
POWER FACTOR CORRECTION MAPPING
The power factor correction (PFC) mapping includes inspection of existing PFC equipment, momentary measurements of electricity quality from the electrical centre, an analysis of power factor correction needs, as well as an assessment of what equipment could be installed to address this. When the site has several electrical centres behind the power grid’s point of measurement, separate measurements can be taken to determine the power factor correction need of each electrical centre.
On the basis of the mapping, the appropriate PFC solution and estimated payback period are calculated. When power factor correction mapping is performed as a follow-up to the TKF analysis of the electricity bill, the price of the analysis is deducted from the invoice.
POWER QUALITY MEASUREMENTS
Power quality measurements are useful for several situations:
- To ensure the quality of electricity in the new building. To identify and repair deficiencies before they cause problems.
- To examine the quality of electricity after installation of new equipment or other significant changes.
- To scan for electrical equipment malfunctions or the causes of failures.
- To determine the quality of electricity at the network company point of connection.
The power quality measurements last between 1-7 days. A comprehensive measurement report compares the situation with the standard for voltage characteristics of electricity supplied by public distribution system (EN 50160) and sets out proposed measures. For example, levels of harmonics, which cause device breakages can be seen from the electricity quality measurements.
INSTALLATION & COMMISSIONING
We offer various services for the equipment based on the customers’ needs. Installation and/or commissioning can be included in the equipment delivery. In connection with initialisation, we can provide training in the correct use and maintenance of the product to ensure that the service life of the product is as long as possible.
MAINTENANCE & EXTENDED WARRANTY
Annual maintenance of reactive power compensation equipment ensures proper operation and safety of the equipment and maximises its lifespan. Annual maintenance checks include component and wire connections, purification and heat scans of the capacitor bank, replacement of filters, and momentary testing of electricity quality with and without the reactive power compensation activated. Momentary measuring reveals possible problems with the quality of the electricity, such as harmonics occurring at the time of measurement. TKF power factor correctors can be equipped with a continuous remote-access measurement system to analyse power quality. If you sign up for a yearly service contract when you purchase your equipment, you can also get a 2 or 3-year extended warranty for your device.
