Switzerland, Zürich: Hitachi Energy presented its solution to protect distribution transformers from transient voltage: transformers with Transient Voltage Protection (TVP®) Technology.
The company held an event to inaugurate its state-of-the-art transformers factory in Bac Ninh, Vietnam at which this pioneering technology was unveiled. More than 200 attendees were at the product launch ceremony at the new company facility with a display of a life-size demo unit. The factory will produce distribution transformers with TVP® Technology integrated into the product, a solution which sets new heights of reliability and resilience for transformers.
When processes require electrical network switching, or in case of nuisance tripping, the transformers can be at risk of premature failure due to switching transients, and result in costly outage. Transient voltage is a silent threat across different segments like data centers, solar and wind renewable power generation, industries, rail infrastructure etc. using medium voltage fast-acting circuit breakers like Vacuum circuit breakers (VCBs).
While Vacuum circuit breakers (VCBs) have excellent arc-quenching capabilities that brings increased safety and efficiency to electrical systems, in certain system configurations and procedural operations, VCB (and SF6) switching can produce fast transient over voltages inside of transformer windings, some leading to failures. These failures result in system downtime and irreparable equipment damage, both incredibly costly to network managers.
Transformers with Transient Voltage Protection (TVP®) Technology provide protection to transformers and downstream magnetic equipment at every single switching instance. Their network agnostic design makes them the best fit, no matter what the network configuration is or how often switching operations are performed. The TVP® technology is an already proven protection in Hitachi Energy’s dry-type transformers, and the technology is now expanding to Hitachi Energy’s liquid-filled transformers.
