Page 2: Specification
INTRODUCTION PEM’s Rogowski Current Waveform Transducers combine high bandwidth, safety, and the minimum disruption to the circuit under test. These instructions should be followed whenever the unit is used. They are intended to help you obtain the best and safest performance from the transducer. - Page 3 CWT ULTRA MINI – ROGOWSKI CURRENT TRANSDUCER 1. Rogowski coil (loop) 2. ‘Free end’ of the Rogowski coil 3. Ferrule (the connecting mechanism for closing the Rogowski coil). 4. Cable connecting the Rogowski coil to the integrator electronics 5. Socket for external DC supply 6.
- Page 4 The voltage rating (safe PEAK working voltage) is clearly labelled on the cable adjacent to the coil. For the CWT Ultra Mini this is 1.2kV peak. Never use at voltages greater than this value. Voltage ratings are only valid if the ‘free-end’ of the coil is fully inserted into the socket, and remains fully inserted during use.

Page 5: Handling Instructions
To achieve such an extremely thin Rogowski coil the CWT Ultra Mini is necessarily delicate. Every effort has been made to ensure that the CWT Ultra Mini is as robust as possible. To prolong the life of the coil please observe the following handling instructions. - Page 6 SWITCHING ON Before installing the CWT and taking a measurement refer to SAFETY AND PRE-USE CHECKS and HANDLING INSTRUCTIONS to ensure safe operation of your CWT Ultra Mini. Do not fit a Rogowski coil to a live circuit; always de-energise the circuit first. 1.
