WebIn North America the three main bushing standards that are used are CAN CSA C88.1, IEEE C57.19.00/C57.19.01 and IEC60137. The CSA standard is in large part an adoption of the IEEE standard with some specific Canadian requirements (e.g. operational capability at -50°C is seen more as a standard requirement than a special requirement). Web2 dagen geleden · Due to the new measuring inputs which conform with the instrument transformer standard IEC 61869, it is possible to connect sensors that consume less power, are safer for operating personnel and use less materials such as iron, copper and cast resin, compared to conventional instrument transformers.
