General Description

Current sensor zero-phase-sequence current transformer TZLV-SESH for 10 voltage class. Transformer TZLV-SESH is used for research VL 6-10 kV with a single-phase earth fault in networks with isolated and compensated neutral complete with the USZ-3S device. TZLV-SESH 10 kV is installed in cubicle switchgear KRU-SESH. Transformer have climate version "U", “T” and category 2 according to GOST 15150-69.

Windings are defended with a protective cover.
Application of fabrication technology “RITZ”.
Assembly convenience of current sensing.
