Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, insulating gas, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in Sulfr hexafluoride gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf6 gas can do in centimeters.Get price

Instrument Maintenance and Calibration System

Preventive MaintenanceConcurrent MaintenanceReliability Centered MaintenanceOperations & Maintenance DocumentationSpare Parts StockingTechnical SupportThe Industrial Instrumentation systems should be part of the overall preventive maintenance(PM) program for the facility. Table 1 provides a list of recommended maintenance activities and frequencies for Industrial Instrumentation and its components. Preventive maintenance schedules for Industrial Instrumentation devices and subsystems should be coordinated with those for the mechanical/electrical systems they serve to minimize overall scheduled downtime. Table 1 Recommended maintenance activities. Note: The Calibration frequency may change based on company recommendations and standards. Many components of Industrial Instrumentation systems, such as relays, are not required to function under normal system operating modes. For this reason, the control system should be tested periodically under actual or simulated contingency conditions. These tests should approach as closely as possible the actual off-normal conditions in which the system must operate. For example, SCADA for standby...Get price

Current and voltage digital transformation in a modern

Conventional and Non Conventional Instrument TransformersMerging UnitConclusionsConventional transformers based on iron cores introduce measurement errors. Due to the wide dynamic range of current signals on power systems, current transformers for protection need large cores to avoid saturation under fault conditions. Due to the nature of the magnetic core material, however, these large cores produce significant errors at nominal current, which renders them impractical for metering purposes. Therefore metering-class transformers need to be introduced resulting in increasing costs. Conventional wired 1A/5A current transformers (CT) circuits have thermal overload constraints, and pose increasing burdens on the core as cross-site wire run lengths increase. Techniques that do not require the iron core of conventional transducers can overcome the limitations. The solutions use different sensor technologies such as optical and Rogowski coils. In practical implementations, the techniques require sophisticated solutions employing digital signal processors and microproc...Get price
