ETOS®: A complete solution for digitalizing transformers at the field level; was recently installed on 3 x 500 kV 250 MVA single-phase transformer banks in Thailand.

The customer had clearly defined requirements:

+ Single hardware set to monitor all 3 single-phase units – While still giving individual information on each TX and OLTC
-> Custom format developed

+ The customer was looking for extended service intervals
-> Currently, the next servicing is recommended in 14 years, which is double the previous interval

+ The customer needed the ability to connect their current sensors from a 3rd party supplier
-> Previously, by installing DGA or bushing monitoring, we could integrate into ETOS®

+ Local support
-> Reinhausen (Thailand) Ltd. has expert staff based locally, which allows the project to continue immediately
