Tester Meter

Working on a commercial 3-phase system, one plug shows power from my tester but nothing when I try to use it??
Plug and light indicate full voltage form multi meter, and plug tester shows everything works, but when I try to plug anything into it, there is no power. Is it an unbalanced phase problem or ???
If its a 480 volt system it could be a delta with a phase out.
There are 2 ways 3 phase transformer systems are connected, Delta and/or Wye "Y". On a three phase Delta system, being that its a "closed loop", if one line feeding the transformer is dead, you will still read 480 across all phases. Check the transformer fuses on the high or input side. (ONLY someone qualified on High Voltage should accomplish this without question!).
These factors also apply to 240v delta as well. But is experience with 480 more commonly.
On a "Y" system, you can check "phase" to neutral or ground. If the phase is good you will get either 120/208 on a high leg delta or 277 on a 480 delta (No neutral on 480 delta...or rarely) on a 240vac delta, there will be a stinger leg, usually phase "B" will read 208 phase to neutral.
Above all be very careful.
