Current transformers/voltage transformers for medium voltage
The great current option
Description:
Medium-voltage current transformers for indoor applications that transfer one or more network-side primary currents proportionally and true to phase into standardised secondary currents. These are isolated in cast resin and, alongside their primary function as current transformers, also act as busbar supports. These current transformers can be used both for measuring and protection purposes.
The medium-voltage current transformers are also available as multi-core transformers. The maximum possible number of cores depends on the output selected and the accuracy class, which specify the core volume. The current transformers are optionally available with primary or secondary switching.
The current transformers with primary switching offer the option of choosing between two primary nominal currents, depending on the connection of the primary connections through parallel or serial circuits. The primary-side nominal currents can be achieved only in a ratio of 1:2. For current transformers having secondary switching, the switching is made possible by one or more pickups. As a result, the primary-side nominal currents can also be achieved in various ratios.
