The Asset CT-1 / x Toroidal Leakage Current Transformer draws attention with the following advantages:

Leakage currents are caused by malfunctions in the electrical networks, faulty infrastructure, problems experienced by the network equipment, or operating methods of the network equipment. These leaks can be determined from the vectorial difference of the current values ​​coming from the neutral and returning from the neutral. Toroidal leakage current transformer (toroidal current transformer) such as Asset RCR-1 series is used to prevent this electrical disturbance from causing life and property loss. The aim here is to measure and limit the amount of leakage, to stop the system without any damage when the limit is exceeded, and to cut off the energy. CT-1 or CTA-1 series toroidal current transformers selected according to wire or busbar thickness are connected to leakage current relay current measurement input and are used when leakage currents are measured.

Currents flowing through the phase and neutral lines as current measurement techniques are collected in vectors and the RCR series is compared to the current value set on the relay.

Generally, the CT series used during cabling or cutting the line current can be installed with toroidal leakage current traces as well as the open type CTA series Toroidal Leakage Current Transformer (toroidal current transformer), which is easier to use, without disturbing the continuity of the system. The CTA-1 series provides fast and easy installation and maintenance at the points where the system stoppage will cause great financial damage, such as factories that manufacture high number of open type trailers.

There are two turns on the Asset CT-1 / x Toroidal Leakage Current Transformer. One is used to measure the leakage current and the other is used for the test function on the RCR type leakage current relays. Test run from an external point can be used to test both the relay and the transformer to see if there is a fault.

Asset CT-1 / x Toroidal Leakage Current Transformer is used in high power and thick panels and electrical panels. According to the official gazette published on July 17, 2013, "Leakage relay (residual flux key) is established in accordance with the principle of electivity in the main panel and secondary electricity panels of the workplace", the use of leakage current relay has become obligatory. For this reason, the use of relays in places such as high-power electric motors, electric distribution panels has become necessary both in terms of material and safety.
