Power networks are subjected to extreme weather events and pollution all-round the year. From lightening to high-speed winds, and from dust storms to environmental pollution; an array of factors could be detrimental to their smooth functioning. The result is the appearance of faults from time to time and disruption in the power supply for long hours, causing huge revenue losses to the utilities. The key to minimizing losses on account of faults lies in identifying the fault locations early and taking timely remedial measures. Raychem Fault Passage Indicators enable utilities to do so with ease. Raychem’s FPIs help electricians attain quick visual or remote indication of the fault occurrence on an overhead electrical system.

Transformer is a vital component of a distribution system. It has to deliver Reliable Power in a safe & efficient manner. However, 8% of the transformers installed worldwide fail on account of improper connector systems. A conventional connector system used for LV cable connection, deploys crimping and tightening of the bolts. Over a period of time, it leads to a loose electrical contacts which causes sparks and hot spots. The contact resistance is high which adds to the losses of ailing utilities. The weight of the connector causes mechanical strains on the bushing of the transformer, leading to oil leakages.

Over 27% of the total electrical energy in India is lost because of Aggregate Technical and commercial (AT&C) losses making a woeful comparison with global standards. If the losses are not kept in check, it is estimated to cost over Rs. 40,000 crores to Indian distribution utilities. The technical losses are primarily because of the type of conductors used, transformer capacity, and other equipments used for transmission and distribution of electricity. The commercial losses are caused mainly due to meter tampering, power theft and collection inefficiency. Raychem understands the problem and offers unique solutions which help Indian utilities to bring down the losses significantly.

The Substation Total Demand Monitor has been designed to provide an easy to install (30-45 minutes), versatile and configurable metrology system. The total demand of the substation is calculated by the summation of the feeder loads and all loading parameters are measured. The system may be configured to measure transformer output and feeders by using Rogowski coils. Busbar voltage phase to phase angles may also be measured for the 3 phases. Working in conjunction with RTU, which provides RS485 over Modbus; the data is transmitted to a central server over GPRS using DNP3NEXUS protocol. This can also be made available to other manufacturer�s host servers if required. Continual logging of metrology values is done via the Modbus interface and all logs are datetime stamped, with the clock being synchronized with central server. Alarms and alerts relating to a range of measured parameters can be sent out.
