TE-qNODE

Ultra-low gradient harvesting

Wireless thermal condition monitoring sensor.

Medium voltage (MV) and low voltage (LV) busbars face a very specific risk of failure: degrading electrical connections. Retrofitting wired or even optical monitoring sensors is usually prohibitive due to cost and inevitable downtime. Thermal imaging only provides an infrequent momentary impression, so most of the operational risk of sudden failure and associated loss of production remain prevalent.

TE-qNODE from Micropelt

The TE-qNODE eliminates this risk at a very attractive price/performance ratio by continuously providing thermal status information which easily enables action either automatically or by human assistance in a control room.

TE-qNODE at busbar

Wireless flexibility allows virtually any number of measurement points per asset without adding any infrastructure cost beyond a single receiver. Adding a TE-qNODE sensor is a matter of seconds. Single handed clamp-on during a regular maintenance slot is easy.

The TE-qNODE is powered by the resistive heat which is produced by the current flowing through the monitored busbar. Even low loads can be monitored as 5 K of gradient between the surface of the busbar and the surrounding air will sustain continuous operation. Thus providing measurements every minute. Critical situations will reliably be detected within seconds from cold start because they always go along with a sudden temperature increase – which will reliably turn on the power and hence the radio.

The TE-qNODE will also monitor any other low gradient surface, provided it can be mounted with sufficient reliability. Refer to our technical staff for customized attachment.
