Until now, there was no reliable method that would dynamically identify if there was a compromised joint / termination on a circuit operating at low load (typically below 40%).
London, UK (PRWEB UK) 31 August 2012
QHi Group introduce Exertherm LoadMap™, a new predictive tool (patent pending) that will dynamically detect & identify compromised joints / terminations residing on circuits operating at low loads (typically below 40% of maximum design load). LoadMap™ provides a new level of protection for all N+1 & N+2 data centres and other facilities operating dual redundancy power systems.
With the growing global acceptance of the 24x7 Continuous Thermal Monitoring system, Exertherm™ sensors are now increasingly being designed and installed into both new-build and retrofit electrical switchgear in mission critical high downtime cost industries such as Data Centers, Oil & Gas projects, Hospitals, Nuclear plants, Shipping, Power Utilities, etc.
In addition, this increasing global demand and acknowledgement of a new ‘best practice’ technology, has been recognised by the 5 major global Original Equipment Manufacturers, who are now adopting and designing / integrating such pioneering technology into their products.
However, as part of QHi’s quest to continually seek to innovate and further endorse the adoption of Exertherm™ technology in industry, QHi have now added LoadMap™ a dynamic and unique technology enhancement to the current leading-edge 24x7 Continuous Thermal Monitoring system.
The enhancement was discovered by recognising that alarm thresholds for hotspots in electrical panels which were used by periodic thermographic inspections internationally were largely based on operating at 100% load. Utilising Delta T to measure temperature abnormalities (note: ΔT indicates the rise over ambient air temperature of the target surface) typically alarm thresholds were thus set at between ΔT 30° > 40°C (ΔT85° > 105°F).
This is a fundamental flaw since the alarm threshold would differ according to the load being applied to the circuit e.g. for a circuit operating at 30% load the equivalent alarm threshold to ΔT40°C at 100% load is in fact ΔT 3.6°C.
This realisation and subsequent innovation was important because it led to the understanding that many businesses who operate dual power feeds, operate them deliberately at low loads; this is so that either for operational or maintenance reasons, load can either be increased / switched between feeds, or entire load switched onto a single feed for a period of time. Until now, there was no reliable method that would dynamically identify if there was a compromised joint / termination on a circuit operating at low load (typically below 40%).
The Exertherm LoadMap™ technology identifies compromised joints on low load circuits, dynamically adjusting the alarm threshold for the load being applied to the circuit. In addition, it also predicts the amount of load that can be applied to that circuit before the alarm threshold is reached. This enables operators of dual feed power systems to identify hitherto “Hidden” problems and verify that loads can be increased / switched safely prior to undertaking the action.
This enhancement has been enthusiastically greeted by major global OEM’s who have already indicated their desire to incorporate the Exertherm™ & LoadMap™ technology as an option for their customers world-wide to ensure they are providing the most superior and up to date technology of its kind to protect its electrical switchgear.
Both Exertherm™ Continuous Thermal Monitoring and LoadMap™ Low Load Protection, are vendor neutral and can be designed into new builds or retro-fitted to existing equipment irrespective of manufacturer.
