In the electrical diagram, the optional accessories are in red. Metering cubicle is not needed Sensors are small and weigh less than current instrument transformers (CT) and voltage transformers (VT) CTs and VTs weigh 18 -27 kg and sensors only 0.5 -2 kg Gas-insulated switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. High Voltage Gas Insulated Switchgear Assembly and Supervision. Systematic gas-insulated technology: Even the busbar system is gas-insulated and is continuously monitored with regard to insulating capacity together with all the other medium-voltage components. If another type of cable bushings are used, please contact the manufacturer. Siemens delivered the first gas-insulated substation for a rated voltage of 420 kV. vacuum circuit breaker 630A and disconnector with a grounding switch in the circuit breaker bay. In TPM type switchgears cable bushings of all leading manufacturers (CELLPACK, 3M,Nexans, Tyco Electronics, F&G, ABB) can be used. However in the TPM C system switchgears, straight or elbow cable bushings are used, depending on the height of the room in which the switchgear cubicle is installed. A cable tray is required under any type of switchgear. Each tank has a safety valve which can be opened to remove the pressure increase caused by internal arc. There is an interlock system between the switch disconnector (circuit breaker, disconnector) and the grounding switch, and between the grounding switch and the masking covers, which prevents incorrect switching procedures. The design of the switch-fuse unit compartment prevents its opening before the grounding switch has been closed. Closing of the switch disconnector in the transformer bay is possible only when the switch-fuse compartment door is closed. For more details, resume or certificate requests, please contact me. Figure 1 shows the suggested cable tray depth.
