substations. All sensors are tested according to IEC 62271 and provide interfaces to industrial standards. The SF 6-gas density sensor is based on the pressure compensated principle and provides a 6.5…20 mA output signal.

Feb 01, 2014The use of SF 6-N 2 gas mixtures in gas insulated electrical switchgear (GIS) is becoming more wide-spread. This is motivated by the reduction of environmental impact associated with SF 6 emission and the increasing number of GIS located in low temperature environments where pure SF 6 cannot be employed. We present a cost-efficient sensor system that tracks gas composition based onCited by: 6

In this paper, we roughly describe the principles and structures for the sensor applications and diagnostic algorithm with together networking and monitoring system for GIS MTR in 154kV substation.

Jindongnan GIS substation, and it was confirmed that the optimal resistance is about 500-700 Ω in permeability and the saturation flux density. Figure 2 indicates the high voltage test setup which is VFTO for different magnetic material for 500 kV at sensor 2 (Figure 2), (a) GIS with an open end at 15 MHz, (b) GIS with the grounded endAuthor: Reem A Almenweer, Yixin Su, Xixiu Wu

With g3, based on a full life-cycle evaluation, the CO2 footprint of gas losses is cut by 98%. Taking the entire substation into account, more than 50% of the CO2 footprint can be saved. GE’s F35-145 kV GIS therefore offers today the lowest CO2 footprint of any 145 kV GIS in the world. g³ tools and handling. A new gas also means new tools.

Sensor nodes, in this case consisting of multiple individual electrochemical sensors, can be low-cost and highly portable, thus allowing the deployment of scalable high-density air quality sensor networks at fine spatial and temporal scales, and in both static and mobile configurations.

substation area more and more impor-tant. ABB pioneered the development of switchgear products with additional inte-grated functions like the Plug and Switch System (PASS), which led to the devel-opment of mixed technology switchgear that provide a functional blend of AIS (air-insulated switchgear) and GIS

designed for Gas Density Monitoring in harsh substation environments. Besides complying to superior EMC and environmental standards, the sensors operate with a 4 to 20 mA current loop technology for high noise immunity. A single Assetguard GDM field device can connect up to 48 sensors providing a cost efficient channel per device ratio.

mostly located, and surrounded by road or river, the urban square is usually located in the high-density area. Due to this reason, the linear park and urban square show low PCI (Figure 8 b).

For instance, a high spatial density of data points is needed for captur-ing noise, whereas temperature can be captured with a lower spatial density. Cambridge (MA, US) where the sensors were

GIS breakers normally have some sort of sensor to get SF6 density as it is now mandatory in many places to monitor at least SF6 leaks. Some will have additional sensors. Monitoring other types of breakers is less frequent except by what is done by protection relays in

Jim Wacker from INCON gave a presentation on the continuous emissions monitoring of substation assets, and describing new technologies (OPTImizer2 and LenSense) can help with emissions monitoring.

Current transformers (CTs) and voltage transformers (VTs) are used extensively in substations for measuring and monitoring voltage and current. These measurements form an essential part of operations and protection functions in the substation, and thus reliability and accuracy of voltage and current transformers (VCTs) is important. A new generation of digital CTs and VTs, […]

The SF6 gas digital online monitoring device for substation on-line monitoring is developed by combining pressure, humidity and temperature sensors in one sensor and by digital circuit. Comparison measurement and test is performed between the SF6 gas digital online monitoring device and the measurement devices at home and abroad.

Modular Switchgear Monitoring (MSM) is an add-on system to supervise, manage and analyze performance of high-voltage switchgear like dead tank breakers (DTB), live tank breakers (LTB), gas-insulated switchgear (GIS) and Plug and Switch System (PASS) hybrid switchgear.
