TZLM-1 current transformer

Purpose of TZLM transformers:

Transformers of current of TZLM are used for giving of food of schemes of relay protection against short circuit on the earth of separate veins of a three-phase cable by transformation of currents of zero sequence. Transformers are intended for installation on a cable: with a diameter up to 70 mm – TZLM-1, with a diameter up to 100 mm – TZLM-1-1 and TZLM-1-2.

Transformers are manufactured in various climatic modifications: "At" or category 2 "T" in accordance with GOST 15150 are also intended for work in the following conditions:

• The maximum working height above sea level should not exceed 1000 m;
• temperature of surrounding: "At" from-45 to +45; "T" from – 10 to +55;
• environment is inexplosive, not containing the substances destroying coverings of metals and isolation (the atmosphere like II in accordance with GOST 15150);
• working situation – any.

Possible options of designation: TZLM1, TZLM1U2, TZLM1-1 transformer
