Expert power quality services
We offer power quality services ranging from electricity bill analysis to sophisticated measurements. We help our clients choose a solution that is functionally effective, cost-efficient, and secure. We provide installation, commissioning, inspection and maintenance services for compensation equipment.
Analysis of the need for compensation
When analysing the need for compensation, we inspect the existing compensation equipment, perform an instantaneous power quality measurement at the switchgear, determine the need for compensation and the required equipment, and verify that the equipment can be installed. When a site has several switchgear units downstream of the network operator’s metering point, measurements are taken to determine the need for compensation at each switchgear unit.
The analysis of the need for compensation determines which compensation solution is most suitable for the site and the estimated payback period. When the analysis of the need for compensation is conducted as a follow-up to TKF’s electricity bill analysis, the cost of the electricity bill analysis is deducted.
Power quality measurements
Measuring power quality yields benefits in various situations:
– Ensuring the quality of electricity in a new building. Any deficiencies identified can be corrected before they cause problems.
– Studying power quality after installing new equipment or making other major changes. Identifying the root causes of malfunctions or failures in electrical equipment.
– Determining the power quality at the network operator’s connection point.
Power quality measurements assess the power quality at a site by taking measurements for 1 to 7 days. A comprehensive measurement report compares the current status with the SFS-EN 50160 standard, which defines the voltage characteristics of electricity supplied by public electricity networks, and provides recommendations for action. For example, power quality measurements can determine the level of harmonic distortion that causes equipment failures.
Installation & commissioning
We offer services related to the equipment according to our client’s needs. Installation and/or commissioning may be included in the equipment delivery. During commissioning, we provide training on the correct operation and maintenance of the equipment to ensure the product has the longest possible service life.
Maintenance & extended warranty
Annual maintenance of the compensation system ensures that the equipment operates correctly and safely, and maximises its service life. Annual maintenance involves inspecting the components and wire connections, cleaning and taking thermal images of the bank, replacing the filters, and taking instantaneous measurements of power quality with and without compensation. Instantaneous measurement reveals any power quality issues, such as harmonic distortion, at the time of measurement. TKF’s banks can be equipped with a continuous, remotely readable power quality measurement function. When you make an annual maintenance contract at the time of purchase, you can also purchase an extended two- or three-year warranty for the equipment. Minor repairs to TKF’s banks during maintenance; no unnecessary travel or repair costs.
