Condition basded monitoring system for gis
GIS
The continuing growth in global population and economy in India is leading to the rising requirement of electrical power and diminishing availability of space (land). For this purpose, the substation equipment have to be made more efficient and reliable to cope up with increase in demand – specially adapting current power distribution and transmission system – and space saving design may help enhancement of utility power distribution system in this scenario – which may be fulfilled by GIS. The phenomenon is quite simple, a gas Insulated substation is an electric power station, in which all live equipment and bus-bars are housed in grounded metal – that is sealed and placed in a chamber filled with SF6 gas. A large space is required for the sub-station with normal Air Insulation Switchgears (AISs), because the required phase-to-phase and phase-to-ground clearances are very large. But as the dielectric strength of SF6 gas is higher than the air, which is necessary for phase-to-phase and phase-to-ground clearances, the required spaces are much lower for all equipment. Therefore, the overall size of each bay – and consequently the whole substation is reduced to about 10% of the conventional air insulation substation. The compactness of Gas Insulated Switchgears (GIS) has a direct influence on land requirement, and land cost. Compact modular designs offer many possibilities in layout design, & allow tailor made applications.
our product offering for GIS/switchgear condition monitoring
online Partial Discharge monitoring
portable Partial Discharge Monitoring
online Partial Discharge monitoring
Utilizing advanced UHF technology, the PDMG-RH system, a member of the highly successful PDMG-R family, is designed for GIS installations. It collects PD data from UHF sensors (couplers) installed on the GIS and transmits the information to software for automatic interpretation and analysis by Expert Software, allowing incipient faults to be avoided and the condition of the long term health of the insulation system to be simply and effectively monitored over the life of the GIS.
