Low-voltage current transformers are available in plug-in designs for switch cabinet and plant construction, with screw-free Cage Clamp and UL approved versions. High-current external-field-compensated transformers are designed for wind energy.
Harmonics measurement transformers enable power quality analysis up to 20 kHz for grid operators and industry, including retrofit versions for distorted networks.
Flexible Rogowski coils can be installed without disconnecting the power circuit. Integrators convert to standard current outputs; universal converters add Modbus and temperature measurement.
Residual current monitors (Type B/B+) measure AC/DC differential currents for early fault detection, with 4-20 mA output for direct PLC connection.
MID-approved energy meters support S0, M-Bus, KNX, Modbus and LAN-TCP/IP, forming a modular ISO 50001-certified energy management system.
