Abstract - Substations are important part of a power system it
helps in transmission and distribution of electrical power system. A substation receives power from generating station by transmission line and further delivers electrical power through feeder and feeders are used to send the power in different areas. Substation main function is to receive energy from generating end transmit at high voltage for economic and reliable supply further reduce the voltage to a value appropriate for local distribution in distribution substation.
A. What is Testing and Commissioning? Here, Testing is process to test various equipment according to their functions and specifications to prove its conformity before installation for electrical system safety and reliability. Commissioning is defined as a process of achieving, verifying, and documenting that the performance of systems, and bring together to meet its definite objectives and criteria according to its quality.
As per IS and IEC standard this paper covers the important equipment functions & their Testing in sub-station. Basically, substation consists of power transformer, circuit breakers, Isolators, Current Transformer (CT), Potential Transformer (PT), Insulators, Lightning Arrester, etc. We have discuss different types of Testing such as Power transformer testing, Current Transformer (CT) testing, Potential Transformer (PT) testing, Circuit breaker testing, Lightning Arrester (LA) testing and Insulator testing. The main aim is to review test according to IS and IEC standards for various equipment tests for improving reliability and to reduce faults chances in future.
B. What is need of Testing and Commissiong? To check performance of equipment, specification, to maintain reliability of electrical system and safety. All the tests are performed before installation. After performing various tests, checking the specifications, connections and completing the installation, we need to charge the line in which the data is verified as per specific standards. III. Testing methods for equipment
Key Words: Substation Equipment, Testing, IS and IEC
standards.
A. Type test Test carried out to prove conformity with their specifications these are intended to prove general qualities & design of a given type of manufactured item. Type testing is testing to determine whether a product or system matches with the requirements which is specified. Beyond simple conformance other requirements for efficiency, meeting rules or standards may apply.
I. Introduction Testing and commissioning of Electric substation equipment is essential to the start newly electrical system for the first time, considering its size, type of new installation, equipment used, ratings, etc. It is a very special and important for facing some unique challenges to electrical person. Inexperience and poor planning will result in delays for start newly installation which can lead to expensively product losses. So to start any project of substation installation the important thing is planning and preparation, from Engineering to commissioning and start up. It provides safety by going through procedure of testing and commissioning for all the Electrical system component. This paper also offers useful guidelines on what to do when things go wrong during this phase and selection of new equipment and what tests are performed before selection of equipment.

B. Routine test Test carried out on each part or item manufactured to check parameters which are likely to vary during production is termed as routine test. In case of mass production, there will be some of the test items that need to be implemented in order to make sure that the quality matches with the given samples. It is conducted on each product manufactured to confirm proper manufacturing of each and every units. This test is essential to be performed on each unit before dispatching the product to site. This tests are intended to check the quality of the individual test unit.
