The BTU Research Electrical Engineering Services & Systems (EESS) team is standing by and available to assist you with your customers needs. Engineers and electrical contractors can select Surge Protection and Power Factor Correction products from the DataSheet included in this section of the website. A Field Audit Form is also available in this section to use when gathering Volt, Amp, Power Factor and KW readings required for us to assist with sizing power factor correction equipment.

When it comes to sustained electrical cost reductions, BTU Research is committed to delivering real value with results, quickly and cost affectively. Our EESS Team will specifically work with engineers and electrical contractors to design a power factor correction solution to improve energy efficiency and reduce or even eliminate Power Factor Correction penalties and demand charges.

Our process is streamlined, takes very little time and provides immediate results. For more information contact our Electrical Engineering Services & Systems (EESS) team at EESS@BTUresearch.com

The BTU Research Electrical Engineering Services & Systems Team (EESS) makes ordering power factor correction equipment quick and easy. Power factor is an essential part of modern electric power systems and is the simplest, most economical means of increasing the capacity of any power system and minimizing energy losses. As with any equipment, an electrical system handles its job to some degree of efficiency ranging from poor to excellent. The measure of electrical efficiency is known as Power Factor.

BTU Research's Advanced Reactive Capacitance Technology (ARC-TECH) uses capacitors installed near the loads or at times at the panel to provide the most economical and efficient way of supplying these kilovars. Low voltage capacitors are traditionally a high reliability maintenance-free device. On the spot delivery of magnetizing current provided by capacitors means that kilovars do not have to be sent all the way from the utility generator to the end user. This relieves both the end user and the utility of the cost of carrying this extra kilovar load.

The BTU Research SURGE-PRO UL 1449 3rd Edition products are used mainly for primary protection of single and three-phase networks at the main electrical panel or for direct protection at a specific load. They provide common mode protection (between the active conductors and protective wire) and are available in single-phase, three-phase, and three-phase+neutral versions. The SURGE-PRO high impulse discharge capabilities classify these SPD's as reinforced Type 2, useful in case of high lightning density areas. IEC60364 standard requests Type 2 SPD at the entrance of installation if the keraunic level Nk > 25. The SPD is based on association of high energy varistors equipped with thermal disconnector and failure indicator, to comply with standards. Remote signaling or disconnection indication is also available for all models.
