W = current *voltage( rms values) As you speak of peak current its rms value is 5.5/sqrt2
1700= 5.5/sqrt2* v so v =1700*sqrt2/5.5= 437.12 volts
(I supposed a monophasic circuit)

Vrms = 0.707 X Peak VAC
1700W / 5.5A X 0.707 for a single phase device.
Edited from here down:
Santman is correct. The current would have to be converted to RMS first, then the VRMS would be equal to the 1700W / IRMS. My original answer was not correct.

rms current is 5.5/√2 = 3.889 A
1,700/3.889 = 437.12 Vrms

P = I x Ep x .707
E = P / I
1700w/5.5a = 309.09v x .707 = 218.52Vrms
