Primary considerations were airtightness, thermal mass and high levels of insulation.

最初考虑的是气密性、热容量和高级隔热材料。

With consideration of ST's insulation and volume, the parameter of ST was determined by the theory analysis and computation of the primary winding.

通过对初级绕组的计算分析及考虑体积、绝缘的基础上，确定了ST的相关参数。

High voltage is applied between the two parts across the insulation being tested, such as the primary circuit and metal enclosure of the equipment under test (EUT).

高压施加于被试的两个相互绝缘的部件之间，例如被试设备的主电路与其金属外壳。
