Abstract: The current measurement apparatus comprises a Rogowski coil (20) comprising a wire or conductor which forms a coil (22) and returns through the coil (22) as a central conductor. The coil (22) and the central conductor are formed from a single conductor or wire and, therefore, no electrical join (for example, a solder join or crimp) is required at the end of the Rogowski coil. The wire (28) used to form the coil (22) anal the central conductor (24) is insulated prior to forming the Rogowski coil. The insulated coating (30) provides better insulation between individual coils and also helps to provide a more even spacing between the coils.

Abstract translation: 电流测量装置包括罗氏线圈（20），其包括形成线圈（22）的线或导体，并通过作为中心导体的线圈（22）返回。 线圈（22）和中心导体由单根导体或导线形成，因此在罗戈夫斯基线圈的末端不需要电连接（例如，焊料接合或压接）。 在形成罗戈夫斯基线圈之前，用于形成线圈（22）的线（28）在中心导体（24）之上分离是绝缘的。 绝缘涂层（30）在单个线圈之间提供更好的绝缘，并且还有助于在线圈之间提供更均匀的间距。
