Transformers also provide an extremely useful feature called isolation, which is the ability to couple one circuit to another without the use of direct wire connections. There are applications where electrical isolation is needed between two AC circuits without any transformation of voltage or current levels. In these instances, transformers called isolation transformers having 1:1 transformation ratios are used.Our Isolation Transformers isolate the equipments from noisy power line hence providing a better option to clients. These remove power line noise, surges, spikes and transients. It also provides high insulation resistance and provides complete electromagnetic and electrostatic shielding.Our range of Isolation Transformers is designed as per the international standards which give an assurance to the customer on the high quality of the product. An isolation transformer does not have a direct electrical path from the power input side to the power output side. The term is also used to define how much electrical isolation exists between the input and output windings. For example when using line-voltage input transformers to power low voltage device handled by humans, a high degree of isolation is required for safety. Isolated transformers often use separate bobbins for the primary and secondary coil windings, but usually the windings are just wound on top of each other with insulation in between. There is usually an electrostatic shield between windings which is tied to transformer case.

Control Transformers for contractor applications have to Energize the coil and Maintain a contact for definite period of time. The initial energizing of the coil takes 5 to 40 mil. seconds and requires 3 to 10 times the normal current. While calculating the VA rating of the Control transformer, this factor should be taken in to account.

We are offering control transformers. Control transformer is a transformer which supplies power to control and / or auxiliary equipment not intended for direct connection to the main source. Control transformers are specifically used to provide control supply voltage for the control circuits of ac motor starters, i.e. Starter coils, timers, indicating lamps electronics protection relays etc. Control transformers for contractor applications have to energize the coil and maintain a contact for definite period of time. The initial energizing of the coil takes 5 to 40 mil. Seconds and requires 3 to 10 times the normal current. While calculating the va rating of the control transformer, this factor should be taken in to account. They are available for single phase and three phase inputs and are in the range from 15 va to 30 kva. construction control transformers are two winding transformers with both windings made of copper. Power house transformers are made of using high quality materials. Electrolytic grade super enameled wire with best insulations are used. Core material are crgo ei or strip cores. Experienced hands with best machines for winding ensures best results with minimum size. Appropriate class of insulation materials are used. Transformers are impregnated in insulating varnish for long lasting performance. Input and out are terminated on bakelite board with proper size of terminals. information required while ordering: a) input supply- voltage, frequency and number of phases i.e. Single or three phases. In case of three phase system type of connection- star / delta / vector group. b) out put voltage and current in of each secondary winding( if multiple out put windings are required). C) class of insulations: d) service conditions if other than standard service conditions. application specific transformers: we make transformers as per specific requirements and some of standard applications are * auto transformers for auto transformer starter, * high voltage transformers, * high current transformers for load testing, * potential transformers for metering and instrumentation, *short circuit-proof transformers, *pulse transformers for power electronics
