This report is to clarify the basic difference between the obsolete KD-4 / KD-41 electromechanical relay and the present design KD-10 / KD-11 Compensator Distance Relays. Organizations which are responsible for theelectric power generation, transmission and distribution of the generated energy, has to deliver energy for their consumers. Please refer to detailed product information. The relay is an electromechanical switch used as a protecting device and also as a controlling device for various circuits, equipments, and electrical networks in a power system. The spring keeps Spring Electromagnet the two contacts separated until the electromagnet is energized, pulling the two contacts together. In fact, some of the first digital computers were built with electromechanical relays as their active elements. The manufacturing processes used to create these relays provides a cost effective solution for many switching applications, but users need to be aware of the limitations just as with any other relay technology. a$���ma���7������F�PH����S>z-�myg���v�Q����UL )��1l�=�m�L��y��Oɔ� E'��1;�$x�zʈ�Y���y����M��|C�B������$�>�@�A+��j�T�� &�����LE�I`b)]3��,��ݿ�0H�����$�خ����n�T��6�}��V��!12�9S�!��ѡ�Q����I%�]��,�8܃��>z&�Y�h���H>Q�����=)+�n��!q?�[��c�����|�?��GJ�'jv�TM��_t�&������ɫ�v��o�kI�{�{�.��V�3���Oc{��Ϭ�I>%U*h���xӪvұ�{z�����m�6������ȡKhM�>T�6tC��@ZF-mD��h���Q�+�C �sqq>�Z��ɰ`ݕ;����OS���8K��,�\ˌ�x\�pr%�*I��w���MH�_�-�f�1��;�+nQOm�'�ǎ7�QK�r9���\�ƴ�;��Ȓ����6��㨁��U#����ć�1���p�V��m641��r���T+|���D7Ϝ���ݻ0e�EqGL�� �v>���p�Z\S�ʏ١^�:}x3��1P�N%��b�R�v5p�Yyx,L���ґ�˚Ū�^�h,:�PV��v�g��Q&�s��sx�ee.

Electromechanical relays have low switching speeds while solid state relays have no such limitations. In what ways are electromechanical relays similar to semiconductor logic gates? An electromechanical relay is an electrical switch actuated by a solenoid. ABB electromechanical relays have protected the power system for more than 100 years, and with the proper inspection, maintenance, and testing techniques, these relays can guard the power system for many more years. J03-EN-01B 153 MY Electromechanical relays Versatile plug-in relay that sets the standard Since they were first introduced, over 500 million of these mini power relays have rolled off the production line. Next is the armature, or the moving part, which is the electronic part that opens and closes. These electromechanical or electrical relays can tolerate some abuse and they are normally relatively tolerate to transient voltage surges or spikes. Electromechanical relays have been the traditional backbone of electrical protection systems. If that conductor is wrapped into a coil shape, the magnetic field produced will be oriented along the length of the coil. x��W�nG���96s���� �m9�9H�XT"Q��������$05{�k}�}�d�:I���������]=.d��_-�,T&���m��D�K}���n�yQ�N��`��e/M�ַ���ۥ�1:xq�\��1J��J�dņ����z��{mB�N� ���D�l�Ѷ/���V���L�3I���k&�K,�>ɘHAMo�L&�[p��[ķ�L��0���c�C������g�^f~])�`u�V��I�ԭ��蚘i�d�k:C9���re��u��RG��� 6�"�Rz��W���6г)@�ax".
