ISO 18095:2018 gives guidelines for the monitoring techniques to be considered when setting up a condition monitoring programme for power transformers and includes references to associated standards required in this process. It is intended to help in the implementation of a coherent condition monitoring and condition-based maintenance programme, such as described following ISO 17359.

ISO 18095:2018 is applicable to single-phase alternating current power transformers of ≥ 1 kVA and three phase alternating current power transformers of ≥ 5 kVA.
