Isolation in AC Motor Drives: Understanding the IEC 61800

• Creepage is the distance along the surface of the isolator package from the high-voltage side to the low-voltage side (Figure 2). Creepage requirements are proportional to the root-mean-square (RMS) value of the working voltage that appears across the isolator according to the system's operating conditions. In some cases, you may need Get price
