Their role in electrical system is of primary importance as they are means of “stepping down” the voltage of a system to measurable values, such as 110V or 100V in the case of a voltage transformer. This offers the advantage that measurement and protective equipment can be standardized on a few values of voltage.We design, manufacture and supply outdoor, oil cooled voltage transformers by high-qualified experience workforce.

OUTDOOR EPOXY MOULDED INSTRUMENT TRANSFORMERS   These are Epoxy moulded instrument transformers place in a moisture proof MS tank and filled with oil. Alarge number of such units have a been supplied by as all over the country.

Direct Measurement of voltage in high voltage system is not possible because of difficulty in electrical isolation of measuring instruments. It is also not possible to use voltage for the system protection due to its high value and difficulty in electrical isolation of protective relays. Therefore, Voltage Transformers are used to step-down the high system voltage to standard value accurately in proportion to their ratio.

Residual Voltage Transformers (RVTs) are a category of instrument transformers which are used in electrical systems to protect capacitor banks from earthing faults and prevent damage. The main function of these class of instrument transformers is to detect neutral to ground fault conditions and discharge the capacitor banks as and when required automatically. In an electrical system in normal working conditions, the windings of an RVT will have no voltage output. On the other hand, in the event of an earth fault a voltage will be developed across the open delta winding of the transformer which will activate the relays and cut the power connection thereby protecting the measuring equipments from damage. The function of RVTs is similar to voltage transformers in some areas. However their and utility is different from one another. It is probably one of the reasons why many people consider RVTs as a sub-group of voltage transformers. Macroplast manufactures Residual Voltage Transformers for varied system voltages. The most common systems voltages are 11 kv, 33kv system voltages in which five limb core construction is employed instead of conventional three limb construction. The outer two limbs carries the residual flux and the secondary windings are connected in open delta fashion.

RESIDUAL VOLTAGE TRANSFORMER is used to detect unbalanced voltage in three phase system and to supply voltage to directional earth-fault relay. For directional earth-fault relay, it is necessary that the voltage applied to voltage coil of the relay corresponds in phase to that of the current in current coil. Such voltage will be the Residual voltage of the system and will be the phasor sum of the three line-to-earth voltages. Residual voltage can be achieved by connecting secondaries of three single phase V.Ts connected in three different phase, in open-delta fashion. It is however, economical to use three phase V.Ts instead of Three nos. single phase V.Ts 'SE' manufactures three phase P.V.Ts suitable upto 33kv system voltage.

Owing to the vast experience of this domain, Starlit Electricals is engaged in manufacturing and supplying Residual Voltage Transformer. RVTs are used for residual earth fault protection and for discharging capacitor banks..   RVTs are used for residual earth fault protection and for discharging capacitor banks. The secondary residual voltage winding is connected in open delta. Under normal conditions of operation, there is no voltage output across the residual voltage winding. When there is an earth fault, a voltage is developed across the open delta winding which activates the relay. 3 phase RVTs typically have 5 limb constructions. Tests A number of routine and type tests have to be conducted on VT s before they can meet the standards specified above. The tests can be d. classified as: Accuracy tests to determine whether the errors of the VT are within specified limits. Dielectric insulation tests such as power frequency withstand voltage test on primary and secondary windings for one minute. Induced High Voltage test: The voltage is induced on the secondary winding at frequency of 100 or 150 Hz for 6000 cycles to verify the with stand ability of the V.T at higher voltages. Impose tests with 1.2/50us wave Positive and Negative flashes of equal magnitude. Temperature rise tests Verification of terminal markings and polarity the routine tests are carried out in the test lab located in our factory premises itself. The type tests are conducted at NABL accredited labs such as ERDA or CPRI located in India.
