The relay (device 59) is a low pickup time-delayed voltage relay designed for insensitive to third harmonic voltages.The relay is rated 67 V continuously and 140 V for 2 min.The relay setting is a tap of 5.4 V pickup with No.10 time dial....
Time dial settingsDirectional overcurrent relayModified particle swarm optimizerPower system protectionThe coordination of directional overcurrent relays (DOCR) plays a very important role for maintaining security and enhancing reliability in the electrical power system. This paper presents the coordination of...
The delay setting mechanism of this series of products is easy to operate and has suitable operating force. When the potentiometer rotates, it feels smooth and has appropriate strength and rotating torque. The dial indicating setting time is clear and easy to read. Danger: It is forbidden to ...
Thecurrent setting of relayis expressed in percentage ratio of relay pick up current to the rated secondary current of CT. That means, For example, suppose, you want that, anover current relayshould operate when the system current just crosses 125% of rated current. If the ...
