Transformers of current of TOP-0,66 and TShP-0,66 are intended for a signal transmission of measuring information to measuring devices and are used in schemes of measurement and the accounting of the electric power in installations of alternating current of the frequency of 50 Hz with a rated voltage up to 0,66 kV inclusive.

Transformers conform to requirements of GOST 7746-2001.
Type of a climatic modification - U3 in accordance with GOST 15150-69.
Transformers are steady against influence of external mechanical factors for group of mechanical execution Sq.m of GOST 30631-99 and no more than 1000 m are calculated on installation at height above sea level.
Execution of transformers under the terms of installation on the place of work - built in, allow installation in space in any situation.
Class of heat stability of isolation - E in accordance with GOST 8865-93.
Cores of transformers of current on primary currents: 10 … 400 A classes of accuracy 0,5S have two options of a design: 1-of electrotechnical steel, 2 - combined from electrotechnical steel and a nanocrystal alloy. Cores of transformers of a class of accuracy: 0,2 and 0,2S have option of a design 2 - combined from elektrotekh-
nichesky steel and nanocrystal alloy. Number of option of a design of the core is a part of a symbol of the transformer of current.
TShP-0,66 current transformers with the widened window for the current carrying tire on primary currents 400 … 4000 A have the following options of execution depending on the window size:
- I - 23х103 mm (transformers on primary currents 800 … 2000 A),
- II - 38х81 mm (transformers on primary currents 400 … 1000 A),
- III - 60х131 mm (transformers on primary currents 1000 … 4000 A).

The core of transformers is made of electrotechnical steel.
Number of option of execution of an opening also is a part of a symbol of these transformers.
Contact clips of a secondary winding are closed by a transparent plastic cover which, if necessary, can be sealed up by the Energonadzor. Transformers pass checking
representatives of Gosstandart.

Existence of the double contacts intended for a possibility of carrying out control checks on object without shutdown of loading and, for an accuracy class 0.5S, 0.2 and 0.2S the sealed-up contact of a potential conclusion for connection of a winding of tension of the counter is provided in a design of TOP-0,66 and TShP-0,66 transformers that interferes with plunder of the electric power.
