Electronic components, such as printed wired boards (PWBs), can be exposed to a variety of harsh conditions. Heavy moisture, chemicals and other corrosive agents, such as H2S (hydrogen sulfide) gas, create a harsh environment that might negatively impact the relay. Adding a conformal coating to the PWB not only protects the electronic circuits from the harsh environment, but also enhances the

With more than 100 years of experience successfully automating and protecting substations around the world, ABB has been chosen to modernize the protection and control relays of the medium-voltage substations in Brussels. Selected by Sibelga, the local distribution system operator (DSO) in Brussels, the Belgian capital will be protected for years to come by ABB’s latest 615 series protection

At the WindEnergy exhibition and Global Wind Summit Conference ABB presents its complete portfolio of solutions for the onshore and offshore wind industry. On the ABB booth, you will see how ABB AbilityTM digital solutions enable cost reductions and performance improvements throughout the whole value chain of the wind industry. Wind farm operators can now access additional data sets and dashboards

ABB today announced the latest innovation to its SafeGear® product line. SafeGear can now be delivered with two potential transformers (PTs) in the same space as the industry standard height for a single PT. ABB’s innovative design, requiring only 19 inches of space for PT compartments, provides the capability of further reducing what is already recognized as the smallest available footprint in

We can all imagine what happens when there is no airbag to deploy but what happens to electrical equipment when there is no airbag equivalent, like an ultra-fast earthing switch (UFES)? The UFES system is a combination of devices consisting of an electronic unit and the corresponding primary switching elements, which initiate a 3-phase short-circuit to earth in the event of a fault. It is similar

In high-voltage transmission protection systems, the merging unit concept is an ideal solution, as there are large distances between the protection relays and the instrument transformers located in the outdoor switchyards. Typically, there are strict requirements to build protection redundancy and the merging unit concept is no longer a new solution but one that has been proven to work in

The Paseo de la Reforma — Mexico City’s iconic front door — is about to get a boost from underground with help from Elastimold® and ABB AbilityTM. ABB, working through local distributor Consorcio AMESA, has won a $6.4 million contract to install 62 units of Elastimold® switchgear systems along 9.1 miles of the street. Considered maintenance-free because Elastimold® contains no oil or gas to

ABB enhances its portfolio of medium-voltage circuit breakers with VD4- Arc Furnace, a unique solution based on vacuum technology and innovative actuation systems, to provide a new high quality, reliable and efficient solution. The VD4-AF circuit breaker, which performs up to 150,000 close-open operations, ensures zero downtime for breaker overhaul thereby reducing total costs of the furnace

As EGEMAC, Egypt’s largest original equipment manufacturer (OEM) of medium-voltage equipment, sought to improve network performance and reduce energy waste, they requested ABB to supply several thousand medium-voltage air insulated indoor switch-disconnectors type NAL/NALF. This is a single-biggest order to an OEM, where ABB’s innovative technologies will support EGEMAC’s delivery of solutions to

Power blackouts can have a severe disruptive impact on society and have been demonstrated to be accompanied by large economic losses. To ensure an uninterrupted power supply in open and closed ring networks, ABB has developed a new solution for the medium-voltage air-insulated switchgear (AIS) UniSec to make the power infrastructure more resilient against such events. The ABB Ability™ Loop Control
