because the internal current goes up and this might cause faster deteriation of the insulation on the wiring, which causes shortcircuit and this may lead to fire, which can burn down your house!
What happens:
In transformers (like input transformer of the equipment) the current goes up.
In motors (like cooling ventilator or compressor) also the current goes up, the turns of the motor depends on the frequency, which means the turns are 17% higher if you go from 50 Hertz to 60 Hertz and 17% lower if you go from 60 Hertz to 50 Hertz, plus in this case the internal cooling is lower!

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card.
