Transformer & Isolator
Transformer - Solar System
A. Electrical Outdoor Isolators
Electrical Isolator is a piece of equipment or an arrangement used in devices and power systems to isolate two circuits or load from the power supply. The main function of an electrical isolator is to isolate two different circuits from each other. Or to isolate a part of the circuit from a power system. Generally, an electrical isolator mainly indicates a mechanical switch and they also designed with electrical arrangements. The main design consideration is its contacts should be open to visible. There are so many electrical equipment’s, devices such as circuit breakers, contactors, etc. are available. They also can isolate the circuits. Then why we required Electrical Isolators. The main reason is visibility. We cannot see the contacts of the circuit breaker or contactor if they are open or close. To make sure the circuit is completely disconnected, electrical isolators are used.

C. Introduction: Electrical LF Transformer
Generally electronic equipments like Transistor, tape recorder, television and other sophisticated equipments are operated on low DC voltage. The DC low voltage can be obtained by two ways i.e. (i) Rechargeable / Dry Batteries and (ii) conversion from A.C. supply. Rechargeable battery is used where electricity is not available. This power source has many draw backs and is also costly. As State Government is going to pay more attention on electrifying the city and rural areas so other DC source i.e. from AC is very cheap and easy to handle. This low DC voltage is achieved from high 220 AC voltage by using a transformer along with rectifier and filter. This transformer is called LF step down transformer which reduces AC high voltage to AC low voltage without change of frequency. This slow voltage is rectified and filtered to get DC voltage.
