Sonus XT – Compact Ultrasonic Testing Device for Preventive Maintenance ON MV HV Switchgear & Cables
uploaded by Chris Dodds - reading time 2 minutes
The versatility of the Sonus XT makes it ideally suited to work with any plant maintenance program and the perfect complement to other Predictive Maintenance (PDM) Technology.
The ultrasonic testing device is easy to use converting ultrasound into audible signals showing instantaneous and maximum sound level readings in decibels.
Ultrasound detection can be utilised to transmit early warning signs that detect faults on connections in cabinets and OHL (when using the parabolic dish – available as an optional extra). Inspections can be performed quickly and safely by plant personnel with minimal training. Fast and accurate diagnosis of problems using the Sonus XT will save you time and money.
The Sonus XT can quickly and safely perform closed panel airborne ultrasound inspections of electrical equipment including Switchgear, Switchboards, Panelboards, Transformers, Motor Control Centers and Process Equipment Panels to detect early warning signs including: Arcing, Tracking and Corona.
➡ Please note Sonus XT detects PD at above 5kV as it definitely won’t work on LV systems.

Sealing Cables

Gavin Cornall (Roxtec)
Roxtec are the world leading manufacturer of cable and pipe sealing transits to protect against water ingress, gas migration and fire spread.
The following article by Gavin Cornall (Global Sub-Segment Manager T&D at Roxtec UK & Ireland) discusses cable sealing applications during running water or “flood” conditions.
Firstly, running water presents a major sealing issue for the installation of mastic type seals, curing and drying is almost impossible. This can place “stress and strain” on work programme completion times, especially approaching handover phase.
Secondly, this applies to any solution used to seal large power cables whether in a one cable, one duct format or passing in a trefoil formation through a larger duct. Such as 11kV and 33kV power power cables feeding MV substations.
The ability of the cable seal to provide reliable operation under high water pressure is essential – the flexibility of the cable seal to be installed during running water conditions is equally crucial.
Roxtec have inspected many seals where over time the cable has caused the sealant to rip or pull out of the substation wall.
Roxtec have also seen due to the weight and orientation of the cables, its almost impossible for the installer to space the cables to get sufficient coverage of compound around the cables to maintain a seal.
Roxtec Cable Transits provide effective protection to LV HV substation cables against flood damage and water penetration be it in dry or wet conditions.
In the Whitepaper we commissioned from EA Technology on Humidity Effects In Substations, I was pleased to see the emphasis on cable retention, both in normal and fault conditions.
It highlighted what I already thought, which is that without the ability to retain, the cable seal will fail over time.
The cable seal may fail on day 1 or year 1 but ultimately it will fail over time.
I would ask the following questions when evaluating cable sealing technology options from either a design, specification or installation perspective.
1) Can it be installed in “running water conditions” – if yes, look a little deeper into what that actually means.
2) Can the cable sealing solution cope with the weight and flex in operation?
When Roxtec developed the UG range, we had a very specific set of tests in mind given our understanding of these 2 issues. We developed a cable seal that was even better than our blue rubber on constant pressure. We quickly realised it could be installed on running water just like its blue cousin, the Roxtec Multidiameter cable seal module.
But most importantly, Roxtec developed specific testing for cable retention and flex.
We wanted to show Roxtec cable sealing solutions could maintain their seal, whilst the cables were pulled, bent and twisted, beyond the maximum bend radius of the cable.
All this whilst we cycled the temperature between +4ºC to +40ºC.
Needless to say it not only worked but it went beyond our expectations.
Our Roxtec H3 200 seal in fact had in excess of 3300nm put on it without failure, that’s over 336 kgs of pull out force!
So in conclusion, I would say if you only take one thing away from reading this article it is always consider: 1) Running Water Installation 2) Cable Retention Performance
