Can the transformer be reviewed against my project specification?

Which routine tests are performed before shipment?
The quality page lists ratio, resistance, losses, impedance, applied-voltage and induced-voltage tests in the factory test bay for every unit.
Can I visit the factory or witness tests? Is a video tour available?
Buyers or their inspectors may visit during production and witness factory tests. Ask the team whether a video tour can be arranged; the site does not state its availability.
