user x: 10 Commandments for Corporate Life

  1. Never trust anyone blindly. Blindly trusting anyone is like driving a car with your eyes closed.
  2. What happens in the office, should remain in office. Never take office gossip to home and vice versa.
  3. Enter the office on time, and leave the office on time. Neither your office nor office meetings are helping you to improve your health.
  4. Never make a Girlfriend/Boyfriend or a Brother/Sister in office. It will most likely backfire.
  5. Expect nothing. If someone helps you feel thankful. Else, you will learn how to do things on your own.
  6. Never rush for a position. If you get promoted, that’s good. If not, it doesn’t matter. You will always be remembered for your knowledge and good nature, not for your designation.
  7. Never run behind office stuff or brood over office matters when you’re outside the office. You have better things to do in life.
  8. Avoid taking everything on your ego. There is a reason why salary is called ‘compensation’. You are being paid. Use your assets to get happiness.
  9. It doesn’t matter how people treat you. Be humble. You are not everyone’s cup of tea.
  10. In the end, nothing else matters more than your health, happiness, and inner peace.

user x : India’s first vertical GIS substation

Sterlite Power’s Gurgaon Palwal Transmission Ltd. (GPTL) project holds a unique distinction. It is home to ‘India’s first vertical GIS substation’- a game-changing solution that has revolutionised the global power transmission sector by innovatively addressing the critical challenge of space.
Gurgaon Palwal Transmission Ltd. is a 130 km-long Inter-State Transmission Line built in an urban landscape, right in the heart of Gurugram and its neighborhood.

Gurugram is a growing economic powerhouse. Understandably, this bustling industrial region registers a high demand for electricity to power its densely populated commercial and residential areas. Building a linear transmission power project in the heart of Gurugram meant a major challenge in terms of paucity of space. Moreover, the transmission lines and towers had to pass through prime real estate and securing the right-of-way (ROW) was a complicated affair. Securing land parcels for constructing three Gas-Insulated Substations (GIS) at Prithla, Kadarpur and Sohna Road was also an uphill task for the team as a conventional 400/220 kV substation, which spreads out laterally, requires nearly 12 acres of land.

In response, the engineering team at Sterlite Power came up with a brilliant idea – a vertical substation which, as the name goes, was developed as a compact, multi-storeyed structure. The innovative idea houses the 400 kV GIS equipment on the ground floor, the 220 kV GIS on the first floor and the open 220 kV switchyard on the roof. The entire GIS substation occupies just 3.8 acres, thus, reducing the land required by as much as 75 percent. There were other space-saving innovations too. For instance, the project built multi-circuit monopole towers across the transmission path, using micro piling to create the foundations.
In addition to space-saving, another remarkable advantage of these vertical substations is the reduced carbon footprint. In the GPTL project, these substations have offset more than 18,000 tons of carbon dioxide emissions annually, vis-à-vis its conventional counterparts. Since real estate for urban power projects remains a continuing challenge the vertical substation design packs a power punch given the numerous advantages. By optimising the use of available land, it offers cost and space efficiencies. Sterlite Power has filed a patent application for this innovation.

In April 2020, amidst the national lockdown owing to the pandemic, the project was successfully commissioned with help from the local administration. It is fully operational today and true to its commitment, playing a vital role in evacuating about 2,000 MW of reliable power to more than three million households in Haryana. By ensuring a reliable supply of power, the GPTL project would be instrumental in reducing the use of highly polluting diesel generator sets in Gurugram and the adjoining areas of Manesar and Palwal, thereby helping to make it DG-set free.

Built on a robust foundation of technology and innovation, GPTL has been a true manifestation of our core purpose — ‘Empowering humanity by addressing the toughest challenges of energy delivery’.

user x : Indias first 1,200-Kv Substation.

India’s power sector will witness a new era in the transmission segment when state-run Power Grid Corp will launch a 1,200-Kv ultra-high voltage (UHV) test station along with experimental lines in Bina, Madhya Pradesh. The investment for the project is estimated at Rs 800 crore. The company is also setting up a 1,200-Kv transmission line for commercial purpose, which will be constructed between Wardha and Aurangabad in Maharashtra.

Till now, the power is transmitted on 765Kv /800Kv lines. The existing 400Kv line can transfer about 600 Mw power, 800Kv line can do between 1,200 Mw and 2,400 Mw and 1,200-Kv transfer 6,000-8,000 Mw, according to experts from the Indian Electrical and Electronics Manufacturers Association (IEEMA), which is associated with the project. With the government’s plan of adding over 100,000 Mw capacity in the coming 12th Plan coupled with the challenges put up by environment hurdles, right of way and transmission losses, there is a need to develop a more sound transmission system.

About 35 manufacturers, including BHEL, Areva, Siemens and Sterlite have joined hands with PowerGrid to establish the 1,200kV test station. The test line in Bina is being constructed with two 1200kV test bays in which the leading manufacturers are providing main equipment such as transformers, surge arresters, circuit breakers, transformers among others. These test bays and test lines shall be used for various field trials initially. “This will usher a new phase in the transmission sector as with a limited right of way (RoW), bulk power will be evacuated from the point of generation to the load centre. The transmission capacity, thus, will be fulfilled with one such line only catering to the capacity of several generators,” PowerGrid Chairman and Managing Director S K Chaturvedi told Business Standard.

According to IEEMA, the first 1,200kV system field was tested and commissioned in the former Soviet Union in 1985 after 12 years of research, which was discontinued after the disintegration of the Union. Then, Japan started developing a 1,000kV UHV system in 1978 and tests are still on. China started developmental work on a 1,100 kV UHV system in 2005 and a pilot project is presently under testing.

IEEMA’s Senior Director Operations Anil Nagrani said, “This will be an experimental line. There are many advantages of setting up a 1,200 Kv line. With unavailability of RoW, space crunch and various environmental issues, the existing power network can be upgraded to 1,200 Kv lines within the same space or little higher space.”

user x: Anyone can tell me What is the function of CBCT??
user x : To senses unbalanced current
user x: Can u plz elaborate it,thanks
user x:
What type of error this
user x: I can’t able to update
user x: Any solution
user x: Normal CT used to measure current in any particular corner phase. CBCT in otherwords called Core balance CT which is placed over the cable OD or all covering all 3 phase bus or cable. So that it measures the unbalance current in the 3 phase system.
user x: Core Balance Current Transformer or CBCT is a ring type current transformer through center of which a three core cable or three single core cables of three phase system passes. This type of current transformer is normally used for earth fault protection for low and medium voltage system.

Secondary of CBCT is connected to Earth Fault Relay. During normal operating condition as the vector sum of three phase current i.e. (Īa + Īb + Īc =0) is zero therefore no residual current in the primary will be present. Here residual current means zero sequence current. Therefore there will not be any flux developed in the CBCT core and hence no current in the secondary circuit of CBCT.

Advantage of Core Balance Current Transformer:
The advantage of using CBCT for earth fault protectionis that only one CT core is used instead of three core as in conventional system where the secondary winding of three cores are connected residually. Thus the magnetizing current required for the production of a particular secondary current is reduced by one third which is a great advantage as the sensitivity of protection is increased.

Also, the number of secondary turn does not need to be related to the cable rated current because no secondary current flows under normal operating condition as the currents are balanced. This allows the number of secondary turns to be chosen to optimize the effective primary pick-up current.

Core Balance Current Transformer is normally mounted over a cable at a point close to the cable gland of the Switchgear. In case cables are already laid in a Switchgear, physically split core, which is also known as Slip-over type CT, are used.

user x : The standard value of rated continuous thermal current is the rated primary current.
user x : Please explaine more
user x : Rated continuous thermal current

The continuous rated thermal current is the current which can be permitted to flow
continuously in the primary winding without the temperature rise exceeding the
values stipulated in the standards. Unless otherwise specified it is equal to the rated
primary current, i.e. the rating factor is 1.0.

In applications where the actual currents are higher than the rated current, a rating
factor must be specified. With a rating factor of for instance 1.2 the current trans-
former must withstand a continuous current of 1.2 times the rated current. The ac-
curacy for metering cores must also be fulfilled at this current. In IEC 61689-2 it is
called extended current rating and has standard values of 120%, 150% and 200%
of the rated primary current.

user x: This message was deleted
user x: If u know the percentage impedance and Hv side voltages at optic tap 1,12,23 Let me assume tap 12 is normal tap
user x: S it is SC TEST ,RESULT ok
user x: We can calculate and ensure she current at particular tap

For thermal overload protection make sure that current thermal state is 0% and inject 3ph current above your settings current and observe the thermal level in your relay, make sure alarm at your set value is coming and it will trip at 100% thermal state. Record the tripping time and compare it with the calculated tripping time ( you can find it from manual)
user x: For NPS either u can use single phase injection then the 1/3 of your injected current will flow as negative sequence current. Observe that current in relay. Do the same as mentioned in thermal protection.

Or u can use
Symmetric component injection method which is available in most of the kits.

user x: Normally what value of Volatge difference is kept in synchronization relay 500kV lines?
Motor protection relay test settings and configuration #vebko amt105 tester
user x: We have 2 set of distance relays set1 and set2 with respective auto recloser AR1 and AR2.
A single auto recloser AR1 or AR2 on 500kV transmission line recloses both BxQ1 and BxQ3.
If line trips on temporary fault and AR1 auto reclosed successfully first time and soon after during reclaim time of AR second fault appears on line then AR1 get blocked as per scheme..and fault is declared permanent. But at the same time AR2 gets initiated by set2 distance relay and it reclosed the line on permanent fault….. This is a single shot scheme….. How to restrain AR2 initiation if fault is permanent??

An Italian company engineering, installation, commissioning and project management [EPCM] needs an electrical engineer, protection with the following conditions and characteristics::
🔷 Project: HV GIS substation
🔷 Location: Southern Hassi Messaoud (Hassi Berkine area), Algeria
I received a request for commissioning activities in Algeria, for some modular HV GIS substation where we did internal FT last year in Italy.

🔷 Duration & Time: Timing can be 6 weeks or more, starting by beginning of May or sooner

🔷 Task: The protection system is ABB with mainly ABB RE_670 (REL/RET) protection but also some Schneider P443 and some Siemens 7SA6xx/7SD6xx.

🔴 Our main target is to perform secondary injection test on a protection system with the assistance from remote for the engineering stuffs, if any, and the local support of the HMI/SCADA specialist.

🔴 System is quite complex but the idea is to have an overlap for at least one full week with somebody of our staff before starting alone.

اEligible applicants are requested to send their request and questions along with the resume to the email or WhatsApp of Kahraba Tavan Azarang Company to the following addresses:
