Blog talks about the technique used in prelocation of Underground faults on cables especially with high resistance
Prelocation of Cable Faults using Secondary Impulse Method
Introduction In our earlier blogs, we discussed the prelocation using the Time Domain Reflectometry (TDR) method, for faults like low resistance, short circuit, ingress of moisture, and open circuit faults. Insulation failure / High Resistance faults cannot be determined using a low voltage source of a TDR or Prelocator instrument. In Mid Voltage (MV) to …

Monitoring the Internal health of Transformer using Dissolve Gas Analyser
In our earlier blog on the transformer, we shared our views on how to detect possible core & winding damage using the Transformer Turns Ratio Meter. The oil which acts as the insulating medium is one of the reasons for internal transformer failure. The oil decomposes mainly due to Thermal, electrical & chemical stress due …

Monitoring and Performance analysis of Solar PV Plant using – Advanced SCADA
the monitoring and performance analysis of solar plants is the necessary part in the perspective of utility and industrial levels. The visualization of assets is more critical in the current scenario because if the visualization of assets is not scalable, robust and smooth it will increase the operation and maintenance costs.
Role of IT in OT Landscape for Power Utilities & Industries
The power utilities like generating plants, power transmission and distribution utilities, Industries etc. are the typical example of an operation technology (OT) landscape. Typically, in these OT industries, the field data are being handled on manual legacy methodology due to which there are numerous data being generated but are available in a silo and which …

Success Story: Industrial Energy Management and SLDC integration over OPGW
It is accepted that industrial activity and the power sector are closely related. Industries use electricity supplied by Utilities through the grid network to power economic activity. While some industries use co-generation (as described in a previous blog) to power their operations, co-generation is not always viable. In a previous blog post, we reviewed the …

Prelocation of Cable Faults using Time Domain Reflectometer Method
In a three-part series on underground cable fault location, we discussed various aspects of cable fault location – from types and causes of cable faults, methodology for identifying cable faults and finally, we illustrated the step-wise process for detecting faults in underground cables. We also introduced the Time Domain Reflectometer (TDR) method for identifying underground …

FLISR Technology for Minimising Power Outages and Improving Network Reliability
Distribution Utilities are obligated to reliably provide round-the-clock electricity to their consumers. With increasingly complex electricity networks, a result of rising energy demand and bi-directional flow of electricity due to increasing use of low carbon energy resources (wind, solar, etc.), Utilities must enhance system reliability for consistent 24x7 power to end customers. While faults and …

Cogeneration Power Plants Integration with State Load Despatch Centre
Cogeneration is typically defined as the sequential generation of two different forms of energy from a single energy source (Bureau of Energy Efficiency). This energy source can be fossil fuel or a renewable resource such as biomass. Cogeneration power plants have been in operation for quite some time in India. These power plants are used …

Evaluation of possible Winding & Core damage through Transformer Turns Ratio Measurement (TTRM)
In a previous blog post, we shared our views on the importance of transformer testing and discussed: a) the principles of winding resistance measurement, b) OLTC condition analysis and c) our thoughts on the ideal kit for transformer testing. In this blog post, we will share our knowledge on assessment of possible winding & core …
