Underground Sensors
NEW Metering Class Current Sensors with Extended Harmonic Performance
Metering Accuracy ElbowSense Ring-Style and NEW Slim Ring-Style sensors now offer flat frequency response through the 80th harmonic while offering up to 0.1% accuracy.
NEW LEA/LPIT Sensors
Low Energy Analog (LEA) voltage and current sensors are now available. Sensors feature RJ-45 connectors and are compatible with LEA-input versions of SEL-700 Series Relays and LPIT versions of Siemens SIPROTEC 5 Relays. A flexible Rogowski coil option is also available for both relay families.
Lindsey offers a complete range of current and voltage sensors for pad-mount, metal-clad, underground, live-front, oil-filled, SF6, and submersible applications.
- High accuracy voltage (0.5% standard, and 0.3% and 0.15% metering accuracy)
- High accuracy (1%, 0.3% and 0.15S) current measurements
- Voltage sensors for live-front, dead-front, oil-filled and SF6 insulated switchgear
- Low voltage analog/low-power instrument transformer (LEA/LPIT) voltage and current sensors meeting IEEE C37.92 and IEC 61869-10, -11, and – 13 standards
- Low voltage switchgear voltage sensors
- Split-core current sensor provides installation flexibility
- Ring-type current sensors for high accuracy applications
- Cast-in cable option for submersible applications
