> Current Measurement > CMD  II C ATA LO G Current Measurement Device Prevent major failures and reduce outage durations by using the CMD  II. The CMD II current measurement device is a non-contact current transformer for protection relay applications. It measures current from ground potential, and requires no foundations or structures. The CMD II uses 5.8 GHz communication technoloy to transfer data securely, economically and reliably. It’s ideal for space constrained retrofits. FEATURES • Compatible with digital relays • Fully configurable CT ratio • System measures line current in real time and transmits data to transceiver • Tranceiver reports current waveform proportional to overhead current SPECIFICATIONS Rated Voltage 38 kV - 362 kV Rated Load Currents 20 A - 4000 A Rated Fault Current 40 kA
