Best answer: What are the types of transformers?

What are the two main types of transformers?

There are two types of potential transformers; the conventional wound type (or electromagnetic type) and the capacitor voltage (potential) transformer. For voltages exceeding 100 kV (phase) the conventional type of potential transformer becomes extremely expensive owing to the insulation requirements.

What are the types of transformers and their uses?

There are several transformer types used in the electrical power system for different purposes, like in power generation, distribution and transmission, and utilization of electrical power. The transformers are classified based on voltage levels, Core medium used, winding arrangements, use and installation place, etc.

What is HT and LT power distribution system?

A low-tension line is a low voltage line and a high-tension line is a high voltage line. In India LT supply is of 400 Volts for three-phase connection and 230 Volts for single-phase connection. High tension or HT supply is applicable for bulk power purchasers who need 11 kilo-Volts or above.

What are the types of transformer oil?

Three basic types of transformer oil used are mineral oil (mostly naphthenic), silicone, and bio-based. Mineral oil based transformer oils dominate the consumption as it has good electrical and cooling properties, and provides cost-effective solution.

What is the SI unit of transformer?

This alternating flux creates an alternating electromotive force (emf) in the transformer’s secondary coil. This phenomenon is called mutual induction. The SI unit name for electromotive force is volt and its symbol is V.

What are the two types of transformers in physics?

There are two types of transformer:

  • a step-up transformer which increases or steps-up voltage.
  • a step-down transformer which reduces or steps-down voltage.
