Instructions for installation, use and
maintenance for current and voltage
transformers
This installation, use and maintenance
guide is valid for current and voltage
transformers operating in indoor
conditions.

1. Service conditions

01 Example of current
transformer label
The transformers should be mounted in dry indoor
conditions where the ambient air is not signifi-
cantly polluted by dust, smoke, corrosive gases,
vapours or salt.
The transformers are designed for standard ambi-
ent temperature between –5°C and +40°C. The al-
titude for use should be lower than 1000 m above
the sea level. The transformers may be used also in
higher or lower ambient temperatures and higher
altitudes when agreed between the manufacturer
and purchaser.

2. Technical details

The technical details for each individual trans-
former are mentioned on the rating plate fastened
on the transformer. Values mentioned on the rat-
ing plate must not be exceeded. Markings used on
the rating plate are as follows:
These instructions are valid for
Current transformer type:
TPU; TPE; TTR; BB; BBO; KOKS; KOFA; IHBF
Voltage transformers types:
TJE; TJCL; TJC; TJCH; TDC; TJP; TJPH; TDP; KGUG; KGUGI
