CMD II ™
Non-Contact Non-Saturating Current Transformer

CMD-II™ installed on 72.5 kV Southern States CapSwitcher

Enhance Your SMART-Grid A non-contact, non-saturating current transformer measures three-phase current at line voltages to protect power systems and to provide critical real-time information to power system operators via SCADA. Its design utilizes line mounted sensors to measure line currents and deliver real-time point on wave current measurements. With no solid insulation to ground, the CMD-II ™ current measuring device is more reliable than freestanding current transformers, and is less costly and less space consuming.

Key Features • Measures phase currents in real time • Immune to CT saturation • Non-contact, zero-footprint design • Outputs an analog secondary current   compatible with digital relays • No batteries at line potential • EM real-time point-on-wave data   transmission • Calibration using standard CT test   equipment procedures • Allows addition of CTs to protection   schemes to meet NERC requirements •Easy retrofit for existing installations Applications • SMART-Grid information point • Capacitor Switchers • Reactor Switchers • Circuit Switchers • Power Transformers • Disconnect Switches • Distribution Poles • EHV Transmission Poles/Towers • Substation Structures • Circuit Breakers

Reliability without compromise.
