5 Technologies to Boost Efficiency in the TD System

HVDC – High-Voltage Alternating CurrentFacts (Flexible AC Transmission Systems) DevicesGas-Insulated SubstationsSuperconductors / Hts CablesWide Area Monitoring SystemsMost of the transmission lines that make up the North American transmission grid are high-voltage alternating current (HVAC) lines. Direct current (DC) transmission offers great advantages over AC, however: 1. 25%lower line losses, 2. Two to five timesthe capacity of an AC line at similar voltage, 3. Ability to precisely controlthe flow of power. Historically, the relatively high cost of HVDC terminal stations relegated the technology to being used only in long-haul applications like the Pacific DC Intertie, which connects the vast hydro power resources of the Columbia River with the population centers of Southern California. With the advent of a new type of HVDC, invented by ABB and dubbed HVDC Light, the benefits of DC transmission are now being realized on much shorter distances. The Cross-Sound Cable connecting Long Island and Connecticut is one example of this technology. Go back to Topics ↑Get price

Myth About gaz sf6 Gas In Electrical Equipment

Aug 24, 2017 · This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC 62271-203) For sealed for life MV equipment a range below 0,1 % per year is common.Get price

Switchgear - Wikipedia

Today, oil-filled equipment has largely been replaced by air-blast, vacuum, or SF 6 equipment, allowing large currents and power levels to be safely controlled by automatic equipment. High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines.Get price

High voltage - Wikipedia

For high voltage and extra-high voltage transmission lines, specially trained personnel use "live line" techniques to allow hands-on contact with energized equipment. In this case the worker is electrically connected to the high-voltage line but thoroughly insulated from the earth so that he is at the same electrical potential as that of the line.Get price

Facilitating Predictive Maintenance of Electrical Assets with

Common Electrical Asset IssuesInspecting Assets ManuallyTemperature MonitoringMonitoring Partial DischargeDetecting UHF Partial DischargeContinuous Condition-Based MonitoringResults from Continuous MonitoringIt’s no secret that downtime can be costly. Many power plant outages are due to failure of critical electrical assets. Independent of the type of power plant, a typical power delivery system includes assets such as generators, potential transformers, generator circuit breakers (GCBs), line disconnect switches, step-up and step-down transformers, segregated and nonsegregated bus ducts, medium-voltage switchgear, and other equipment needed to support the transmission and distribution of power. Electrical assets are subject to overheating due to excessive loads, normal wear and tear, and challenging environmental conditions. Left unattended, these conditions can lead to failures or costly damage to the asset and surrounding equipment, power production loss, and in extreme cases, severe injury or death. While diagnosing and detecting all potential problems in the myriad mix of equipment (such as generator vibration or transformer oil deterioration) are important, this article will conce...Get price
