We have a site with metal halide lamps connected and after current measurements, we found that the 3rd and 5th harmonics are about 13% meanwhile harmonics 11 and 13 are more than 30%.
As all know, lamps are connected as single phase loads at 277VAC for total load of 6kVA per each phase (480...
hi
for a local hydroelectric facility, we have supplied several on-line inverters (15kva, 277) for emergency lighting. Four years after the start-up, the real 125V dc load has reached a value greater than the design and the problem is that these inverters are feeded by the 125vdc substation...

hello
a MV 450hp 4.16kv motor was dropped at the client,

Rotor and shaft look good.

I apologize if this is a trivial...
good day
I am looking for a replacement diode or supplier
for IR P/N: 200HF120PV and 200HFR120PV.
Since we have a lot of rectifiers in the field with this diode and its 1/2" UNF 20 thread, which is a must for us.
If anyone can help, I appreciate that.
Thanks.
