摘要:
A cable connection assembly (100) comprises an adaptor body, a terminated electrical cable end (16e) received within the adaptor body wherein the electrical cable end (16e) is terminated by a connector (24), a radio frequency (RF) sensor tag (30) secured to the connector (24), and an RF reader (40) externally mounted on the adaptor body. The RF sensor tag (30) comprises a temperature sensor and an antenna. The RF reader (40) is configured to transmit an interrogation signal to the RF sensor tag (30) that provides power to the RF sensor tag (30) and causes the temperature sensor to detect a temperature of the connector (24) and generate a temperature data signal, and that causes the antenna to transmit the temperature data signal. The RF reader (40) is configured to receive the transmitted temperature data signal.
摘要:
A Low Voltage, "LV", network automation system (100) is provided which enables utilities to remotely identify location of LV faults on their networks, isolate these faults and re-energising the healthy LV circuit by remote control. The hardware for this system is designed to be retrofitted into existing LV switchgears (120,125) and panels which enables the network change over to be done cost effectively and with minimum interruption to the network. The system also enables utilities to monitor load flows on the LV networks and identify circuits which are overloaded and gives control room operator options for redistribution of network load where possible.

摘要:
The present invention relates to an electric switch (1) for high currents, in particular with a high short circuit withstand performance in the kA-range. Electric switches of this type are known and in use, but the electrical contacts in these switches are liable to separate due to blow-off or induced electro-magnetic forces during the passage of high short circuit or fault currents. The present invention provides an electric switch (1) that maintains a high mechanical contact force (F) but requires a lower mechanical force to open and close the switch and vice-versa.
