- a. Conventional outdoor.
- b. SF^ gas insulated metal enclosed substation.
- c. Hybrid substation.
- d. Only b and c.
- e. All of these.
What are the classifications of the substations according to the design?
The operating voltage based substations are high voltage, extra high voltage, and ultra-high voltage substations. The importance based substations are grid and town substations. The design based substations are indoor, outdoor, foundation mounted and pole mounted substations.
What is 66KV substation?
66KV Control & Relay Panel It is intended to provide State-of-Art substation control, protection and metering system and shall be integrated with SCADA system. The protection, metering & control system shall be as per SLD and specification of 66KV CRP. The microprocessor based Transformer monitoring relay.
What are the types of substations suitable for voltage 66 kV and above Examveda?
The bus connecting series fields in parallel.
How is a substation designed?
The design of the substations mostly contains The Transformers, Circuit Switches, Breakers, Transmitters, and the Capacitors. The transformers carry out the task of stepping down the high voltage electricity to lower voltage electricity which is suitable enough to send through the distribution wires.
What is kV substation?
This is accomplished by suitable apparatus called Substation. For example, generation voltage (11KV or 6.6KV) at the power station is stepped up to high voltage (say 220KV or 132KV) for transmission of electric power. The assembly of apparatus (e.g. transformer etc.) used for this purpose is the substation.
How many types of substations are there?
The transformer substation is an important element of any electrical power system and is the heart of this transmission network. It can be mainly classified into four sections as a step-up substation, primary grid substation, secondary substation, and distribution substation.
What is GIS room in substation?
Gas insulated substation (GIS) consist of components where active parts on high voltage potential are located in the middle of the aluminium alloy pipes and held in this location by epoxide resin insulators. The pipes are filled in with insulating gas and have earth potential.
Why is 11kV 33kV 66KV?
But we already know that there are some voltage drop due to the resistance of the transmission lines. For this reason, they transmit 10% extra voltage….If it is not related to the form Factor, What is it then?
| Sending Voltage | Receiving Voltage |
|---|---|
| 20kV x 10% = 22kV | 20kV |
| 30kV x 10% = 33kV | 30kV |
| 60kV x 10% = 66kV | 60kV |
What is Erection of substation?
Job DescriptionTechnician – Substation Erection and Commissioning is responsible for carrying out all types of technical activities for construction of a new substation (66/11kV and 33/11 kV) for erection and commissioning, which includes installation of various equipment in the control room and outdoor switchyard …
Which type of fuse is generally used on 11kv pole mounted substation?
The 11 KV incoming lines are connected to the transformer through the gang isolator and HT fuses. A triple pole mechanically operated gang isolator switch is used.
What is a kV substation?
Which gas is used in substation?
SF6
A gas-insulated substation (GIS) uses a superior dielectric gas, SF6, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in SF6 gas inside grounded metal enclosures.
Is 66 kV high voltage?
LV Low Voltage – up to 1,000 Volts. MV Medium Voltage – 3.3kV, 11kV, 15kV, 33kV, 36kV. HV High Voltage – 66kV. EHV Extra High Voltage – 132kV 245kV 400kV.
