Are you curious to know what is ASD in BESCOM? You have come to the right place as I am going to tell you everything about ASD in BESCOM in a very simple explanation. Without further discussion let’s begin to know what is ASD in BESCOM?

The efficient distribution of electricity is crucial for the smooth functioning of any modern society. In India, the Bangalore Electricity Supply Company (BESCOM) plays a vital role in providing electricity to the city of Bangalore and its surrounding areas. As part of its infrastructure, BESCOM employs an important component called an Automatic Switching Device (ASD) to ensure reliable and uninterrupted power supply. In this blog post, we will delve into what ASD is in the context of BESCOM and its significance in the power distribution system.


ASD stands for Automatic Switching Device. It is an intelligent electronic device used in power distribution systems to monitor and control the flow of electricity. In the context of BESCOM, ASDs are strategically installed at various locations throughout the distribution network, including substations, transformers, and feeders.

Function And Significance:

ASDs play a crucial role in maintaining the stability and efficiency of the power distribution system. They are designed to automatically detect faults, monitor power quality, and quickly respond to any abnormalities or disruptions in the electrical network. The primary functions of ASDs in BESCOM include:

  1. Fault Detection and Isolation: ASDs continuously monitor the flow of electricity and are programmed to detect any faults such as short circuits, overloads, or other abnormalities. Upon detecting a fault, the ASD promptly isolates the affected section, ensuring that the fault does not propagate to other areas of the network. This helps minimize power outages and improves the overall reliability of the system.
  2. Automatic Switching and Restoration: ASDs are equipped with the capability to automatically switch power supply sources when necessary. In the event of a fault, the ASD can redirect power flow to alternate routes, ensuring a seamless and uninterrupted supply to consumers. Additionally, once the fault is rectified, the ASD facilitates the smooth restoration of power, minimizing downtime and inconvenience to end-users.
  3. Power Quality Monitoring: ASDs continuously monitor the quality of power being supplied to consumers. They measure parameters such as voltage levels, frequency, and power factor, among others. By keeping track of these parameters, the ASDs help identify any deviations from the desired standards and enable prompt corrective actions to maintain optimal power quality.

Benefits And Impact:

The implementation of ASDs in BESCOM brings several benefits and positive impacts to the power distribution system and its consumers:

  1. Enhanced Reliability: ASDs ensure that faults are detected and isolated swiftly, reducing the impact on the overall system and minimizing disruptions in power supply. This results in improved reliability and reduced downtime for consumers.
  2. Quick Restoration: With automatic switching and restoration capabilities, ASDs facilitate rapid recovery from faults. The automatic rerouting of power ensures that affected consumers experience minimal interruptions and can resume normal operations swiftly.
  3. Improved Power Quality: ASDs continuously monitor power quality parameters, allowing for proactive measures to maintain stable and optimal voltage and frequency levels. This results in a more reliable and consistent power supply for consumers, reducing the risk of equipment damage and operational inefficiencies.
  4. Efficient Network Management: The intelligent monitoring and control features of ASDs enable BESCOM to optimize the distribution network. This leads to efficient load balancing, reduced power losses, and better utilization of resources, ultimately benefiting consumers and the environment.


ASDs are vital components of the power distribution system employed by BESCOM in Bangalore. By incorporating intelligent monitoring and control functionalities, these devices enhance the reliability, efficiency, and power quality of the network. Through fault detection, automatic switching, and restoration, ASDs minimize downtime and ensure uninterrupted power supply to consumers. As BESCOM continues to prioritize the modernization of its infrastructure, ASDs play a significant role in building a robust and resilient power distribution system for the growing energy needs of Bangalore.
