TLP190 Low-Power Current Transformer
Phase current measurement range: 5-2500 A
LPCT Low-Power Current Transformer
TLP130 and TLP190 are low-power current transformers, current probe with
voltage output conforming to IEC 60044-8 standard.
TLP130 and TLP190 current transformers in toroidal structure are designed to
measure currents from 5 to 2500 A (1250 A for TLP130) using the 100 A/22.5 mV
proportion, and can be used for different rated current values as they are installed
on isolated cable.
■ The same probe measures the phase currents between 5-2500 A
■ Accuracy guarantee in the measurement range:
□ Protection: class 5P for 5 A-40 kA
□ Measurement: class 0.5 for 100-2500 A (0.75 for 20 A, 1.5 for 5 A).
■ Easy installation:
□ Secondary cabling ready for connection
□ Easy connection on isolated cable in each cubicle type.
■ Safe use:
□ Secondary circuit trips under load.
