Insulation Coordination is essential for minimizing disruptions and costs caused by insulation failures, ensuring operational and economic efficiency. It plays a vital role in verifying the appropriate rating and placement of lightning arresters in substations, maintaining the required protective margins for optimal safety and performance.
SEN EDS leverages advanced DIgSILENT software, complemented by an extensive library of IEEE HV Engineering resources, to conduct Insulation Coordination Studies for both AIS and GIS substations up to 400kV. Our expert solutions are tailored to meet the needs of clients across Assam, ensuring enhanced substation reliability and efficiency.
About Insulation Coordination
The primary objective of an Insulation Coordination Study is to align the insulation levels of switchgear and associated equipment with protective measures. Our analysis evaluates overvoltage scenarios such as cable energization, re-energization, fault application or clearing, and capacitor bank switching to determine the optimal size and placement of surge arresters.
Our methodology adheres to IEC 60071 and the IEEE standard “Modelling Guidelines for Switching Transients” established by the IEEE Switching Transients Task Force. Detailed modeling includes stray capacitance and network parameters to deliver precise results, ensuring system safety and performance.
Insulation Coordination involves determining optimal insulation levels for various power system components, such as cables, GIS equipment, and transformers. The process includes:
- Selection of insulation structures that withstand expected voltage stresses.
- Placement and rating of surge arresters for enhanced protection.
- Validation of insulation adequacy against stresses from conductor switching, transformer operations, and fault conditions.
By conducting rigorous studies, SEN EDS ensures that your substations across Assam are safeguarded against insulation failures, delivering reliable and efficient long-term performance.
