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 …
