TRANSFORMER

A Three phase Control transformer are to supply power to control and auxiliary equipments. which are not intended to connect direct supply. Control transformers are used to control supply voltage for control circuits of Ac starter motor i.e starter coils, timers, indicating lamps, electronics protection relay, etc.,  A control transformer is used to supply control power thus allowing lower, safer and more efficient control circuit voltage to be used in high working voltage applications. The excellent inrush current handling characteristics of the transformer also makes the system more efficient.

INVERTER & ON LINE UPS transformers are used to convert DC supply (Normally taken from batteries or Rectification of mains) to AC by High Frequency switching of the Input DC through MOSFET/IGBT Bridge. These transformers have high leakage inductance to filter out the switching waveform to a smooth Sine Wave with a minimum THD (Total harmonic distortion.) Additional leakage inductance is achieved either by placing the primary and secondary coils apart or by increasing the build of coils. Sometimes an additional shunt core is also placed, which connects to the input winding only and helps to smoothen the wave shape. These transformers can be manufactured using EI, UI or strip core as per rating of the transformers. These transformers are normally forced cooled because of high harmonic losses in them.

STEP UP transformer is one whose secondary voltage is greater than primary voltage. This kind of transformers used to “Step Up” the voltage applied to it.

STEP DOWN transformers is one whose secondary voltage is lower than primary voltage. This kind of transformer used to “step down” the voltage applied on it.

RESIN CAST Control Transformer are used to reduce supply voltage to 690 V or lower, hence act as Step down Transformer depending upon requirement, for the operation of electromagnetic devices e.g. Contractors, Solenoids, and Relays & Timers. They are specially designed to accommodate the momentary in rush current caused when components are energized without allowing secondary voltage to fall below specified limits. Resin Cast Transformer offered is developed using latest technology support and can be made available up to 1000 KVA in class H/F insulation. Featuring both LV winding support coming embedded in resin, these transformers can be provided in dry type Resin Cast. Some of its features include suitable for power transmission and transformation process systems, extensive usage in areas like hotels, business centers, chemical industry and others; providing for reliable and stable usage, transformers developed using cold rolled silicon steel sheet, low voltage winding support and others.

Variable vertical transformers from ACTIVE for the power supply of diverse products are preferred for use in test engineering, glass industry, stabilizer, etc. as well as in electroplating applications. In these areas, all solutions are tailored to individual customer requirements. Whether for test facilities, the glass industry, electroplating or regulation of industrial furnaces – ACTIVE ELECTRICALS develops and manufactures specific variable transformers for continuously variable adjustment of voltages up to 800 volts and currents up to 1500 amperes.

This variac construction looks like a conventional 3 ph transformer as can be seen in the picture. The spatiality of this lies in winding Cu strip of appropriate cross section edgewise. This reduces the length of the column to 1/4 as compared to winding width wise thus making it compact. This column is then polished & roller carbons are made to make contact with winding for current collection. Due to circular column construction, a Double Carbon assembly can be provided giving two outputs 180° out of phase (or as it is known + and – type). Then this type of  variac can give +/- type output with carbon assembly moving in opposite directions (up/down). For large current ratings these columns can be paralleled. Also being in three phase construction it can be used for higher Currents in delta type connections.
