                                        空气相对湿度不大于90%；              
                                              
                                        海拔高度不超过3500米；              
                                              
                                2、高压耐压机，工频耐压机，交流耐压机工作电压              
                                              
                                        电源控制箱（台）输入电压为工频220V或380V、相对误差不超过±10%；（具体使用电压根据用户所定试验变压器规格选取）              
                                              
                                              
                                              
                                3、    高压耐压机，工频耐压机，交流耐压机的选择              
                                        其高压侧额定电压应不小于被试品的最高试验电压，额定电流不小于被试品的最大电容电流。              
                                        被试品的电容电流和试验变压器所需容量计算公式为：              
                                              
                                        I        =        2π        f        Cx        U        ×        10        -6              
                                              
                                        U        I        =        2π        f        Cx        U        2        ×        10        -9              
                                              
                                        式中        I        —        被试品电容电流，A        ；        f        —        电源频率，        Hz；              
                                              
                                        Cx        —        被试品电容量，μF        ；        U        —        试验电压有效值，V；              
                                              
                                        Se        —        试验变压器所需额定容量，        KVA              
                                              
                                        被试品电容量Cx可由交流电桥测出。常用的被试品电容量按下表选取。
