Retrofit
Retrofit is a cost and time efficient alternative to the worn-out switchgear replacement. It is possible to replace oil or SF6 circuit breaker with Tavrida Electric vacuum circuit breaker retrofit. Compared to full replacement switchgear retrofit allows the switchboard to be refurbished within short time without long power supply outages.
- Reliability of a brand new switchgear.
- Saving on CAPEX by renewing only the worn-out parts while benefiting from new technologies.
- OPEX reduced due to the modern maintenance free TEL VCB.
- Increased personnel safety:
— Mitigate risks of electrical flash fatalities.
— Mitigate risks of power outages resulting in dangerous accidents.
- Possibility to further increase the performance by implementation of:
— Fast transfer switch – restores the power supply in less than 50 ms to ensure the uninterrupted process by using for switchgear retrofit circuit breakers with the fastest timings from Tavrida Electric.
— Fast acting Arc Flash Protection– fault clearing time less than 30 ms– increasesthe safety of personnel and limits the switchgear damage in the event of internal arc fault.
