New Strikesorb single-MOV TVSS module

Raycap has developed a single-MOV module with a high surge handling capability that absorbs and dissipates the excess energy of lightning strikes and power surges in a safe manner, making it suitable for installation in oil, gas and petrochemical equipment applications. Designated Strikesorb, the TVSS module exceeds the stringent requirements of the revised UL-1449 standard, without the use of internal fuses. Strikesorb provides complete and uninterrupted protection through its ability to sustain multiple and successive lightning strikes and power surges without requiring maintenance, even under harsh environmental or poor power quality conditions.

Designed to be installed in locations where the risk of direct lightning strikes is high, or where there is a history of frequent surge-related equipment failures, Strikesorb provides uninterrupted protection from surge currents of up to 200kA. Strikesorb's modules are comprised of a single large distribution-grade metal oxide varistor disc, either 40mm or 80mm in diameter. It is encased in a hermetically sealed aluminum housing - providing uniform distribution of the surge current over the total area of the MOV protection element, resulting in a high-energy handling capability combined with ultra-low let-through voltage to the protected equipment and long maintenance-free service lifetime.

Unlike conventional TVSS systems that employ parallel arrays of smaller components with 90° angled lead wires to each device, Strikesorb's patented monolithic design provides a straight electrical path directly to the suppression element, providing extremely low contact resistance and a good heat dissipation mechanism to prevent aging of the MOV. The Strikesorb module exhibits low clamping voltage and can be directly connected on the power bus bars inside the cabinet of the equipment after the main circuit breaker.
