stromberg relays

[techpc]

Hi,

I need to perform some secondary testing on different type of stromberg relay. Do anybody have any reference manuel on timing relay (SPAT), earth fault relay (SPAJ)(SPAU) and differential relay (SPAD)or a link that I could find any information.

It looks like ABB but Stromberg. They have some manuals online. If you come across any original manuals, I would like to get a copy.
