HARTING High-Precision And Residual Current Transformers

HARTING’s current transformers have been developed in close collaboration with chief companies in wind energy plant construction, specifically to meet their requirements. These transformers are highly reliable functionally and offer high mechanically stability as well. They are well suited for industrial sectors like transportation applications.

High-precision current transformers

The product line includes current transformers for high precision measurements of up to 7000A. The main applications where HARTING’s high-precision current transformers are used include energy systems in wind turbine and solar power facilities. These transformers are connected to display devices like electricity or voltage meters. With these transformers, you can have precise billing with very accurate measuring over the entire measuring range. The robust design and high degree of protection against surge currents and over-voltages also protect downstream measuring devices. In addition, the simple and safe connections are secured by screw terminations. These transformers are suitable for use in even the most extreme conditions, due to their wide temperature range of 40-55°C. When you order these high-precision current transformers from HARTING, you will also have access to primary rail mount and secondary clamp cover, which ensures a simple installation process.

Residual current transformers

These transformers are designed to detect residual currents at an early stage. Depending upon the finding, they generate output signals that can be used to take the necessary troubleshooting action, before a protective mechanism is triggered that may stop the facility. These transformers have a compact design and wide opening for cables, with an optimized housing design to ensure high holding forces of up to 250 kg! Moreover, they are suitable for extreme environmental conditions with a wide temperature range from -15 to +55°C. This property makes them specially optimized for wind energy applications, wherein they measure the difference between currents in the outgoing and return conductors for consumer loads. They are designed for a maximum cable diameter of 110mm and can measure differential currents up to 10A, within a turns ratio of 1:600; and residual currents in single or multi-phase power supplies. The possible frequencies range between 5 and 400 Hz. The 1:600 ratio is ideal for connecting to protective relays or post-processing electronics.

Other products

Both the above mentioned transformers from HARTING meet the strictest demands for measurement quality and for preparing operational data. Along with these quality transformers, HARTING is also well known for manufacturing a wide range of connectors, like circular connectors, data connectors, electronic connectors, power connectors, heavy duty connectors, and modular rectangular connectors. The latest in the series are Han-Smart intelligent connectors from HARTING. These components are used for easily connecting devices and equipment for industrial applications. They are widely used in industrial and manufacturing areas, automation, power generation and distribution systems, industrial electronics, and telecommunications. The other components manufactured by HARTING include current sensors, encoders, high speed backplanes, and PCB terminals; all of which can be easily availed at Alltronix, the leading and most trusted HARTING distributor in Pune, Delhi, Mumbai, Bangalore, Chennai, and Hyderabad.
