An optimal energy quality is of the utmost importance on yachts
The right quality of voltage and current (Power Quality) is essential to ensure the reliability of electrical installations on yachts. As a result of the increased use of converters - such as LED lighting and inverters - excessive harmonics may emerge in voltage and current. This can create problems for the safety, reliability and capacity of the electrical installation. A poor Power Quality can reveal itself in the flickering of lights, heat generation, overloading of generators and switchgear and the accelerated aging of connected equipment.
To avoid problems, certification companies impose requirements with regards to the maximum harmonic pollution on yachts. A frequent set requirement is a maximum harmonic distortion in the voltage (THDU) of 5%.
Malfunctioning of sensitive equipment
Shortened life of electrical equipment
Disturbance in the accuracy of measuring and security systems
Increased temperature in cables, transformers and distributors
Energy losses and an increased risk of fire
Specialist on yachts
For over five years, our Active Harmonic Filters are installed on yachts to optimize the electric energy quality. Our clients see the benefits this provides in terms of safety, reliability and capacity. Our engineers are aware of all electrical aspects on yachts. Not only does HyTEPS deliver a product, we also provide services such as Power Quality surveys and measurements, commissioning and service visits.
HyTEPS works closely with Eindhoven University of Technology. Some of our products are installed in the Power Quality lab of the Faculty of Electrical Engineering for demonstration and testing purposes. At the Eindhoven University of Technology we regularly provide training for our (potential) customers and we work with some employees of the TU / e in the field of testing (new) products.
Optimizing the electrical energy quality on yachts
By means of Active Harmonic Filtering
An advanced method to reduce harmonics and keep them within the prescribed norm of 5% THDU is the application of an Active Harmonic Filter. The installation of an Active Harmonic Filter optimizes the Power Quality. The Active Harmonic Filter (AHF) is installed parallel to the installation, which allows harmonic distortions created by multiple devices to be reduced with just one Active Harmonic Filter.
Case with an Active Harmonic Filter
A HyTEPS Active Harmonic Filter (AHF) is installed on a yacht. During the sea trial, the filter is turned off for a short period of time, resulting the total harmonic distortion of the voltage (THDU) immediately to rise immediately to unacceptable values (see chart).
