Description

TOL-SVEL current transformers of placement category 2 according to GOST 15150 are designed for installation in complete switchgear (switchgear) internal installation or other closed switchgear. Transformers of placement category 1 - for installation in open switchgears.

Design version TOL-SVEL-10M-32.1 (32.2) - for installation in high-voltage mine switchgear and shale mines, hazardous by gas and dust. The transformers are used for transmission of measuring information signal to measuring, protection, automation, signalling and control devices in AC electrical circuits of 50 or 60 Hz frequency.

Design version TOL-SVEL-10M-32.1 (32.2) is also designed to test the performance of the maximum current protection in the absence of load in the primary circuit.
