How to perform Flash Testing of a Revenue Meter?

[bilalwirk]

I work at a substation protection systems manufacturing factory and we manufacture/test panels for 380/132/115kV Systems. Recently we started manufacturing Metering panels as well and as part of the Inspection and Test Plan there is a test item mentioned as "Flash Test" which targets the revenue meter itself and not the complete panel. I have tried asking the utility for which we are producing the panels on how to conduct this test and I have not received anything from them. I have to prepare a test instruction and guideline to perform the test in the factory.

I think this relates to the testing of the dielectric strength of the internal wiring of the meter but I am unsure on what voltages I should use, where to connect the test equipment, and what test standard to follow with regards to the time of the test. Looking for help from anyone here who has performed a "Flash Test" during Factory Acceptance Testing.

This is a question that is a bit outside of what we answer, answers will be limited.

It is, what it is! Flash testing is trying to know how much your equipment leaks when a rather high value of voltage is applied to it. By definition, leakage current is from electricity-conducting parts with respect to the ground of the equipment. The usual voltage is 300% of the rated.
