PTW3-1-60
The PTW3-1-60 Series of potential transformers are designed to give accurate
measurement of medium voltage systems up to 5KV by stepping down higher voltages
to 120 VAC. Useful for monitoring and measuring larger power systems and distribu-
tion networks containing medium voltage loads. These devices have increased capa-
bility to drive larger VA loads.
