motor readings start looking erratic, the failed transformer has to be replaced with a unit that matches the original mounting and ratio. The DELIXI SDH-0.66 current transformer — model LMK3 (SDH)-0.66 — is supplied new with a 20\/1 ratio, Ф30 primary turns, and 0.5 level\/unit accuracy. It is listed as a current transformer with a 0.66A current rating. Before fitting, confirm the existing unit's markings and wiring arrangement against these figures.\u003c\/p\u003e\n\u003cp\u003eTypically used in electrical distribution and switchgear to measure alternating current and provide isolated, proportional low-current signals to monitoring, control, and protective relays.
