OVERVIEW
This reader is dedicated to switchgear monitoring with wireless passive SAW temperature sensors and
UHF partial discharge detection. It is designed for interrogation inside metallic cavities like the
switchgear cabinet and tuned to be compliant with IEC 62271 enabling a license-free use in switchgear
worldwide.
1.0 AVAILABLE PRODUCTS
This manual covers the following products:
-AMS01-T: Temperature monitoring only.
-AMS01-P: Partial discharge monitoring only.
-AMS01-TP: Temperature and partial discharge monitoring.
1.1 INSTRUCTIONS FOR USE
The AMS01 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 discharge
combined with ambient temperature and humidity is measured by antenna pairs and prevent
equipment failure.
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.
The system has ± 2°C precision (only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation is to be expected).
WARNING
THE READER IS NOT INTENDED FOR INSTALLATION INTO MEDIUM OR HIGH VOLTAGE COMPARTMENT
ASSETS. ONLY SAW TEMPERATURE SENSORS AND RF ANTENNAS ARE INTENDED FOR INSTALLATION
INTO MEDIUM VOLTAGE COMPARTMENTS.
