    I am looking for means of determing the frequency at a busbar in a power substation. What instrument do i have to use?

    Thanks in advance.

    You can use an oscilloscope and a pair of rubber boots (do not let your probe actually make contact with the busbar!)

    A frequency counter.

    Make sure your will and other final wishes are in order if you are going into a substation and are asking this kind of question. Not trying to be rude, but some things need to be well understood before trying to tackle the type of hazards that exist in substations. Best answer to your original question would be a telephone to call the power company. Frequencies of power distribution systems are very precisely controlled to permit tying multiple power generating facilities onto the power grid.

    how about using a large inductor (large in H, etc) made of 32-40awg and then encapsulated in epoxy, or glued to the bottom-inside of a thick pyrex beaker/jar, etc. if the freq counter is sensitive enough you should be able to read freq from a short distance, if not sensitive enough then you can make a small amplifier to feed the freq counter. maybe using a laser to read info from the reflected beam? not really sure of best way, just giving you a wacky answer to a wacky question.

    why do you need to know this info?

    Just measure the frequency at home on the SECONDARY of a small transformer.
