TUP_R Protection transformers (homopolar)
Current transformers for the measurement of homopolar currents. They have a low transformation ratio and high sensitivity.
These large window-type transformers allow all 3 current phases to pass through the transformer core in order to detect current unbalance (or earth leakage currents if the neutral is included).
They are designed to accommodate several cables, but can also be used with busbars. They are encapsulated in resin.
