1.2 INSTRUCTIONS FOR USE
The HTR02 reader is dedicated to monitor electrical equipment like switchgears. The temperature of
live conductors is measured by SAW sensors and prevent overheating and overload. Partial discharges
are measured by antenna pairs and prevent equipment failure. Ambient temperature and humidity
measurements are also available through an optional environmental sensor connected with wires to
the reader.
The reader is intended to be installed in low voltage compartments of switchgear or in similar type of
assets. It can also be installed in a weatherproof environmental enclosure.
The reader is intended for use at a maximum altitude of 5 km, typically between -20°C to +70°C (refer
to reader specification for the complete specification) and between 10% to 95% non-condensing
relative humidity.
WARNING
THE READER IS NOT INTENDED FOR INSTALLATION INTO MEDIUM OR HIGH VOLTAGE COMPARTMENT
ASSETS. ONLY SAW TEMPERATURE SENSORS, ENVIRONMENTAL SENSOR AND RF ANTENNAS ARE
INTENDED FOR INSTALLATION INTO MEDIUM VOLTAGE COMPARTMENTS.
