Offshore wind power is eco-friendly new regeneration energy producing electricity using a strong wind of the sea. Offshore wind power consists of pitch controller, nacelle, blade and transformer. Insulating oil for transformer needed to low pour point, high flash point and biodegradable considering the low temperature of the sea and environmental pollution. In this study, polyglycerol fatty acid ester was prepared polyglycerol and fatty acid using various catalysts for insulating oils. We investigated the effect of catalysts on the yield of polyglycerol fatty acid ester. In addition, we were measured the pour point and flash point of the prepared polyglycerol fatty acid ester.
