ALTERNATIVE CURRENT & VOLTAGE SENSORS LPCT–THYSENSOR ALTERNATIVE CURRENT & VOLTAGE SENSORS LPCT ThySensor

LOW POWER CURRENT TRANSFORMERT – LPCT The LOW POWER CURRENT TRANSFORMER sensor (LPCT type) is a voltage output sensor compliant to IEC 60044-8 standard. Very large range of use in one model only from 50 to 1250 A. It is not necessary store different models in stock. Thank to the RJ45 voltage connector LPTC grants safety of operation. No dangerous effects in case of unwanted secondary opening.

LOW POWER CURRENT TRANSFORMERT – LPCT LPTC uses RJ45 connector No screws for the connection but easy click! Rated primary current Dip-switch selectable. Its value is a combination between: 50 – 100 – 200 – 400 – 800 – max value 1250 A. Shielded cable suitable for high interference environments.

LOW POWER CURRENT TRANSFORMERT – LPCT TECHNICAL FEATURES IEC 60044-8 standard rated primary current 100 A, rated extended primary current 1250 A, rated secondary output 22.5 mV, accuracy class for measuring 1, accuracy class for protection 5P, rated short time thermal current 31.5 kA x 3 s Highest voltage for equipment Um 3 kV

THE BEST SOLUTION IN TERMS OF RELIABILITY AND EASY INSTALLATION ThySensor THE BEST SOLUTION IN TERMS OF RELIABILITY AND EASY INSTALLATION

FOUR DEVICES IN ONE SENSOR Electronic current transformer Electronic voltage transformer Capacitive divider for voltage-indicator lamps Insulator

ThySensor BENEFITS Current, voltage, voltage-indicator lamp voltage and insulator in the same component. Low size and low weight; installation inside limited size MV switchgears is possible. Galvanic insulation for current and voltage measurements. Single model suitable for measuring electrical quantities in a wide range of applications, inventory management is optimized. Absence of saturation and ferroresonance phenomena. High measurement accuracy. Shielded cable suitable for high interference environments. RJ45 voltage connector grants safety of operation. No dangerous effects in case of unwanted secondary opening.

ThySensor INSTALLATION EXAMPLE

TWO DIFFERENT TECHNOLOGIES voltage transducer -> based on an electrical field sensor, galvanically isolated from the busbars. current transducer -> based on a special Rogowski sensor. HIGHEST ACCURACY BOTH FOR MEASURING AND PROTECTION
