4 1 general information a standards b cooling code and insulation liquid the iec and bs standards for transformers and their parts are the most widely applied. A current transformer without primary conductor and primary insulation of its own which can be mounted over an insulated cable or an insulated busbar. I is the rated line current of the transformer. Learn how our transformer flex center can help you meet unique general purpose and distribution transformer needs that cannot be met with standard offerings.

Kolma is usually used together with earth fault protection relay. Low voltage transformers complete range of current transformers 50 models from 1 a to 8 ka. Department of energy s 2016 transformer efficiency changes. Foreign standard applications 87 8.

Current transformers cable type kolma are suitable for the measurement of the sum of three phase currents in a 3 phase cable. Special applications 83 7. Is a type of instrument transformer that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an ac.
