Facility generator and transfer-switch test — ZRH

计划安排

The facility runs its periodic test of the generators and automatic transfer switches in ZRH. The site is transferred to generator and back under load. The UPS covers the transfers; machines do not notice. We post it because the site is on a single source for a few minutes during each transfer.
