We present measurements of triple gauge boson coupling parameters using data recorded by the OPAL detector at LEP2 at a centre-of-mass energy of 172 .A total of 120W-pair candidates has been selected in the , and decay channels, for an integrated luminosity of 10.4pb-1. We use these data to determine several different anomalous coupling parameters using the measured cross-section and the distributions of kinematic variables. We measure =,=, = ,=, = ,and =.Combining the result with our previous result obtained from the 161 data sample we measure =.All of these measurements are consistent with the Standard Model.
