PEMUK电流探头CWT系列介绍
CWT Ultra-mini具有极薄的可绕夹式Rogowski线圈，其横截面通常为1.6mm。 这种薄的线圈可以在功率电子转换器最难到达的部分中测量电流，而对被测电路的干扰可以忽略不计。
The CWT Ultra-mini has an extremely thin, clip-around Rogowski coil of typically 1.6mm cross-section. Such a thin coil enables currents to be measured in the most difficult to reach parts of a power electronic converter with negligible disruption to the circuit under test.
