We regularly encounter specific site challenges which require bespoke solutions. As a result we use a modular approach to building optimisers (VO units) which can include any or all of the following :
• Available for all transformer loads up to 3,000kVa (4,350Amps).
• Built to BS61439 and BS61558 (low voltage switchgear) standards under ISO9001 (2015) process accreditation.
• Configured to fit specific available space.
• Configured to allow cable connections to left, right top or bottom of the unit.
• Can be supplied fully weather proof to allow positioning outdoors.
• 5 adjustable voltage reduction settings (6,7,8,9,10%), so optimisation can be sensitive to specific site requirements. alternative reduction settings are available with bespoke units.
• BrownOut™. Automatic low voltage seamless inhibit feature which ensures the optimised voltage is never too low
• Optimisation Bypass (sometimes referred to as inhibit, or bypass). A simple turn of the key switch takes the optimiser seamlessly into inhibit mode so the Grid supply to site is delivered unchecked. In this mode the optimiser can be both serviced and the reduction settings adjusted without any interruption in the power delivered to site.
• TrueBypass™, (sometimes referred to as a System Bypass or Wraparound Switch). Security of supply is guaranteed. The provision of a simple switch allows even non-technical staff to quickly disconnect the optimiser. Used in the unlikely event of a fault on the system this feature connects the site directly to the Grid supply as well as electrically isolating the optimiser.
• Intelligent monitoring / reporting Review historical grid voltage, optimised voltage and current down to minute intervals, review your half hour energy consumption
download data for analysis alter optimiser settings.
• 10-15 year Manufacturer Guarantee. Subject to model and servicing.
• Power Factor Correction. Reactive power charges are increasing and the issue of supply limits can at least in part be addressed by the inclusion of a fully automated dynamic PFC module within the optimiser.
• Harmonic Filtration. All electronic appliances and machinery generate harmonic distortion, the results of which are problematic for many businesses. Harmonics not only waste energy, but cause serious issues like the overheating of distribution transformers and cabling, sometimes with catastrophic consequences. Premature failure of machinery and unexplained ‘anomalies’ in machine control systems often result in costly production stoppages. The inclusion of a fully automated dynamic Harmonic mitigation module within the optimiser will protect you against these problems whilst ensuring you remain compliant with IEC or G5/4-1 (whichever is applicable to your operation), which specifies the enforceable design limits for levels of Harmonic distortion.
• Lightning/Surge Protection. Whether concerns arise from increased climate volatility, or whether you’re aware of renewable generation causing increased incidence on the Grid of transient surges, the increased sensitivity of electronic equipment in particular means Surge Protection is a vital tool to give customers peace of mind. Lightning and surge protection is now mandatory for all businesses, as detailed in BS7671 the current 18th Edition Wiring Regulations. The majority of insurance providers insist on compliance with BS7671 as part of their terms and condition of cover, if you do not comply you are not covered!
