Hello,
I need to PAT test a range of single-phase and three-phase transformers, from 15kVA up to 90kVA. These include both isolation transformers and step-down transformers.
While I have experience with general PAT testing and various PAT tester devices, I'm unsure of the best procedures when it comes to testing larger items like these.
For example, I understand that performing a leakage test using a traditional PAT tester isn’t feasible in these cases. Any guidance or best practices on how to approach testing of this kind, particularly in terms of safety checks, insulation resistance, earth continuity, and functional testing would be greatly appreciated.
Thanks in advance for your help.
