Breakthrough Universal Switchgear Monitoring Solution at CIRED

The new wireless battery-less temperature system for continuous surveillance of switchgears successfully launched a few months ago will be showcased for the first time at CIRED on SENSeOR’s booth.
SOPHIA ANTIPOLIS, France - June 10, 2015 - PRLog -- After the successful commercial launch of the new Energy S1 systems a few months ago, SENSeOR couldn’t miss the opportunity to showcase these innovative solutions to Electricity Distribution main players at the next edition of the biennial conferences held in Lyon, France, in June. At CIRED, from the 16th to the 18th of June, on Booth L4, visitors will discover these small, light, totally passive and wireless temperature sensors enabling the control of overheating at the very heart of T&D equipment, like on the circuit breaker arms of medium-voltage Air Insulated Switchgears. With modular fastening system, or a single, integrated screw, these tiny sensors can also be placed on the cable connections and on the busbars inside the cabinet.

This system overcomes the difficulties of cable installation in retrofit, decreasing considerably the installation time versus a fiber optic solution for instance. It also measures accurately with direct contact the most critical points, and doesn’t require a clear line of sight, unlike thermal imagery. With up to 15 points monitored in a single MV cabinet, it allows very early warning in case of abnormal temperature increase, to prevent failures and apply condition-based maintenance. The continuous measurement with infinite autonomy also enables trends analysis, as the system can feed temperature data to a central control system 24/7 with Modbus-RTU communication protocol.

Such temperature surveillance enables load and overload management, with maximum efficiency, yet enhanced safety for users and operators, and guarantees life-cycle cost reductions. It grants a very quick and highly positive ROI to the implementation of this cost-effective monitoring system.

SENSeOR designed this breakthrough system thanks to the revolutionary SAW technology (Surface Acoustic Waves) applied to sensing, and tested it on key OEM’s equipment with the most demanding levels of dielectric robustness, RF-signal stability, and safe and reliable operation under high-voltage and current (545 kV, 5 kA), and the resulting high electro-magnetic fields. SENSeOR also put a lot of efforts making the system very easy to install and commission, facilitating the configuration with “smart” detection of sensors and system set-up.

CIRED’s visitors will be offered free demonstration of the system in their own equipment to discover all its benefits, live! As the system is the only multi-point SAW solution certified for worldwide license-free use, installation is eased in any country.

As it’s so quickly commissioned, we can also install it during the conference in any CIRED’s exhibitors switchgear showcased.
