2. LOW POWER CURRENT TRANSFORMERT – LPCT
The LOW POWER CURRENT TRANSFORMER sensor (LPCT type) is a voltage output sensor compliant to IEC 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.

3. 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.

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

7. 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.

8. ThySensor INSTALLATION EXAMPLE

9. 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
