EWSK 30 is a 4000 Series primary winding measuring current transformer which allows to take the primary current in the system (from 10 to 20A) and bring it to a value of 5A or 1A suitable to be read by measuring instruments such as digital indicators, analog meters, ESAM transducers and network analyzers (e.g. models ID3004-TA, MI96C, MT-Ca, MT-C, MT-PA1, E2002, E92992, E742002 etc.). The EWSK 30 transformer is the ideal solution for your system and guarantees an accuracy class of 0.5%, a FS5 safety factor and an insulation class E. The test voltage is 3kV per 1 ‘and is built according to EN 60044 / 1-2 and IEC 61869/1 + 2.
