The major challenge in Indian power sector is operating upgrading of the transmission & distribution lines with efficient meteringApplication of smart grid devices for consistently condition monitoring of overhead lines &substation can decides the action of maintenance required and thus condition-based maintenance (CBM) technique can be implemented. To meet ever increase in demand, reduction of value of losses, utilization of huge renewable energy and absence of automation in power Transmission & Distribution, there is need of Preventive Maintenance (PM) & logy(RCM).
The financial growth of India also depends on availability of electricity. Indian power sector having characteristics as shortage of generation and high T & D losses up to 30% of total electricity generation with some parts of states of country up to 40%. When losses due to theft are added in the total then average losses increases up to 30%. The economical loss reaches at 1.5% of the national GDP which is increasing. To maintain stability of power system up gradation is essential. Transmission system is operated & regulated as per the Regulations & standards given by Central Electricity Regulatory Commission (CERC), Central Electricity Authority (CEA), State Electricity Regulatory Commissions (SERC). At present Maintenance technology is one of the topics of R & D for various countries.
Ability to maintain a steady frequency within a nominal range, following a disturbance resulting in a significant imbalance between system generation and load
of interest is the overall response as evidenced by mean frequency, rather than relative motions of machines
In a small "island" system, frequency stability could be of concern for any disturbance causing a significant loss of load or generation
In a large interconnected system, frequency stability could be of concern only following a severe system upset resulting in the system splitting into one or more islands
Depends on the ability to restore balance between generation and load of island systems with minimum loss of load and generation
Generally, frequency stability problems are associated with inadequacies in equipment responses, poor coordination of control and protection systems
Cable sizing to withstand short circuit currentLeonardo ENERGY
In a cable a short circuit causes very extreme stresses which are proportional to the square of the current:
• A temperature rise in the conducting components subjected to current flow such as conductor, screen, metal sheath, armour. Indirectly the temperature of adjoining insulation and protective covers also increases,
• electro-magnetic forces between the current-carrying components.
The temperature rise is important for its effect on ageing, heat pressure characteristics etc., and should be limited to a permissible short-circuit temperature. The thermo-mechanical effects of the current shall also be considered.
For a given short-circuit duty therefore the short-circuit capacity of a cable installation is to be investigated with respect to all these parameters. For multi-core cables in most instances the thermal effect - related to the magnitude of fault current and clearance time - is the critical parameter, since the cable will normally have enough mechanical strength. With single-core cables however, in addition, the mechanical effect - related to the magnitude of the peak short-circuit current - is of such significance that, next to the thermal, the mechanical with- stand of both cable and its supports is to be investigated.
Also accessories must be rated with respect to thermal and mechanical short-circuit stresses.
The short-circuit withstand of a cable system is not quantitatively defined with regard to permissible number of repeated short circuits, degree of deformation or destruction or impairment quality. It is expected, however, that a cable installation will remain safe in operation and that any deformation remains within tolerable limits even after several short circuits.
The significance of power factor correction (PFC) has long been visualized as a technology requirement for improving the efficiency of a power system network by compensating for the fundamental reactive power generated or consumed by simple inductive or capacitive loads. With the Information Age in full swing, the growth of high reliability, low cost electronic products have led utilities to escalate their power quality concerns created by the increase of such “switching loads.” These products include: entertainment devices such as Digital TVs, DVDs, and audio equipment; information technology devices such as PCs, printers, and fax-machines; variable speed motor drives for HVAC and white goods appliances; food preparation and cooking products such as microwaves and cook tops; and lighting products, which include electronic ballasts, LED and fluorescent lamps, and other power conversion devices that operate a variety of lamps. The drivers that have resulted in this proliferation are a direct result of the availability of low-cost switch-mode devices and control circuitry in all major end-use segments: residential, commercial, and industrial.

On Load Tap Changer (OLTC) is used in "High Power Transformers" to control output voltage, when electric load on transformers get increase the output voltage get decrease due to internal voltage drop inside winding, change in tap is required to maintain output voltage. OLTC is a device which perform tap changing in High Power Transformers during On Load conditions and is powered by a motor.
