A range of high quality ring type Crompton Instruments Current Transformers with one metre flying leads, suitable for primary currents from 60 up to 2500A with 5A secondaries, has recently been released by Tyco Electronics.
The cost-effective and versatile tape wound DB series current transformers are easily and quickly installed where conventional foot/busbar mount devices are not practical due to space or location. Long flying leads can easily be terminated wherever convenient and provide a consistent and versatile connection to any measuring/indicating equipment in applications such as switch gear, distribution systems, generator sets and control panels.
Featuring Class 3 accuracy and Class E insulation, DB series current transformers aren’t liable to vibration issues when fitted in an alternator box and can withstand an overload of 1.2 times rated current continuously. Designed for an operating temperature range from +20 up to +70 degrees Celsius, the devices are compliant with IEC44-1 EN60044-1.
