General Description

Measuring through transformer TPL-SESH for 10 voltage class. Transformer is used for signal transmission of measuring information to the measuring instruments, protection of automation, signaling and control. TPL-SESH-10 is installed in cubicle switchgear KRU-SESH. Transformer have climate version "U", “T” and category 2 according to GOST 15150-69.

The presence in the line through and supporting-pass transformers.
Opportunity of making secondary winding by a flexible wire.
Wide ranges of nominal limit multiplicity and safety factor of devices.
