Consultancy
RST Net provides specialist consultancy services for the design and optimisation of electrical power systems, including substations, transmission and distribution networks, and industrial installations.
Design
RST Net provides engineering design services for new electrical installations, as well as the modification, refurbishment and expansion of existing facilities. The company works closely with asset owners to develop practical, reliable and cost-effective solutions tailored to their operational requirements. RST Net also collaborates with leading domestic and international engineering partners, equipment manufacturers and consultants to deliver design solutions that meet customer specifications and comply with applicable industry standards.
Smart Solutions
The transition towards smarter electricity networks has accelerated in recent years, driven by advances in digital technologies, fibre-optic communications and intelligent automation. These smart solutions enable improved monitoring, control and protection of electrical systems, delivering greater reliability, efficiency and operational flexibility.
One example is the digital substation, where protection, control and monitoring functions are performed by distributed Intelligent Electronic Devices (IEDs) interconnected through high-speed fibre-optic communication networks. Compared with conventional substations, digital substations offer significant advantages in engineering, installation, commissioning and ongoing operation. They also substantially reduce the amount of copper cabling required by replacing traditional hardwired connections with fibre-optic communication systems. RST Net has participated in the delivery of several digital substation projects in Iceland, including installations at Hnappavellir, Sauðárkrókur and Varmahlíð, demonstrating the company's expertise in modern substation automation and digital power system technologies.
Energy Efficiency
RST Net helps businesses improve energy efficiency and reduce electricity consumption through the optimisation of electrical systems and equipment.
Improving energy efficiency is an essential part of reducing operating costs, enhancing system performance and lowering greenhouse gas emissions. RST Net works with customers to identify practical opportunities for energy savings by assessing the performance of existing electrical installations and recommending cost-effective improvements.
Measures such as power factor correction, load balancing and power quality optimisation can significantly reduce electrical losses and improve the efficiency of power systems. Depending on the application and the condition of the existing installation, these improvements can reduce electricity consumption and deliver measurable savings on energy costs.
Power Quality
Modern electrical installations increasingly rely on electronic equipment such as LED lighting, variable speed drives, power electronic converters, automation systems and robotics. These devices can introduce electrical disturbances into the network, resulting in harmonic distortion, phase imbalance, voltage fluctuations and other power quality issues.
RST Net provides comprehensive power quality assessments using advanced monitoring and measurement equipment. Parameters including voltage, current, harmonic distortion (up to the 51st harmonic), phase imbalance, voltage flicker and other power quality indicators are recorded and analysed. Monitoring is typically carried out over a period of up to one week to provide an accurate representation of the operating conditions within the electrical installation.
Maintaining good power quality improves the reliability and performance of electrical systems, particularly in facilities with a high proportion of sensitive electronic equipment. By identifying and correcting power quality problems, businesses can reduce unplanned downtime, extend the service life of equipment, improve production efficiency and lower maintenance costs.
