Abstract - This application note describes the benefits of global compensation over local compensation of harmonics in plants with numerous large variable speed drive, such as water treatment plants. By carefully applying global compensation instead of local compensation, a solution with a certain degree of redundancy is usually significantly more cost efficient. The results are general and does not only apply only to water treatment. It is also demonstrated that by carefully sizing a system, oversizing can be avoided.

Through our acquisition of Netpower Labs we have moved deeper into the datacenter segment enabling full system supply of 380 V DC together with our active filter offering. Comsys has supplied ADF solutions on several sites in Europe and Asia and Netpower is the pioneer in 380 V DC solutions enabling 10% electrical power savings in datacenters. The OCP philosophy of open systems and search for better ways to build datacenters offer a great opportunity for us as enablers of power infrastructure technology. Power quality and energy efficiency are big issues for the datacenter industry and we see a great opportunity to contribute solutions in these fields.

Comsys new lifting tool is designed so that service can be performed in an easier, safer and faster way. The lifting tool is easily mounted onto the P300 cabinet and is made of aluminium for lighter weight. The lifting beams are made of steel, so that they with ease can handle the load (see picture & movie).

Lifting tool roof
The lifting tool is designed to build very little above the cabinet that sometimes can be limited in space.

After mounting the lifting tool into the roof frame of the cabinet the lifting tool is secured. After this the modules that weigh approximately 150 kg can in a safe and secure way be lifted either up or down into the cabinet.

During lifting operations, the lifting tool can be moved in and out using the rails in the cabinet roof. Therefore, the modules can be pushed in and out for easy access and safer handling of modules during high load.

Also, the lifting tool can be moved from one module to another without the need to dismantle them from the frame.

This lifting tool is CE certified and can be folded together for easier transportation.
