What are the 2 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 is a transformer symbol?
A schematic diagram is a graphical representation of an electrical or electronic circuit. … Dot convention markings use dots on the transformer schematic symbol as a way of specifying the winding direction between input and output and therefore the polarity between windings.
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.
Which transformer is used in home?
In distribution networks, the step-down transformer is commonly used to convert the high grid voltage to low voltage that can be used for home appliances.
