Rutech Premag System
The connection of a power transformer to the network can arise some problems such as high inrush currents, sometimes up to 20 times of the nominal current. This inrush period can last for more than 5 or 10 seconds. That can cause many problems like: voltage drop on the network and physical tension on the cables and the windings of the transformer itself.
The Rutech premag system is a system that prepares the power transformer for the connection to the network.
The premag is connected to the windings of the secondary of the power transformer and premagnitize the core prior the connection of the primary to the network, after the premagnitation of the core the power transformer is ready to be connected to the network. The result is no inrush current.
