Get a quote
The Zelisko GAR20/3K1 is a current transformer built in accordance with the IEC 61869-2 standard and manufactured according to drawing JW873/17. Designed with a rated insulation level of 17,5/38/95 kV at 50 Hz, this unit features a primary to secondary ratio of 3500 to 1/1/1 A. The device incorporates three separate cores, each delivering a rated output of 30 VA with an accuracy class of 5P 20. For electrical fault resilience, the current transformer handles a short-time thermal current Ith of 100 kA for 1 second, and a dynamic current Idyn rating of 2.5 times Ith. This multi-core configuration enables simultaneous measurement and protection functions within high-voltage electrical installations.
