What Is the 3 kVA Three Phase Transformer Used For?
It is a teaching transformer for the three-phase part of an electrical machines syllabus in engineering colleges, polytechnics and ITIs. Students use it for open-circuit and short-circuit tests, load tests and the efficiency and voltage regulation worked out from them, and to see how a delta-star transformer shifts the phase of the line voltages and provides a neutral on the star side. Because the connections are made on colour-coded banana terminals, they can be changed quickly between experiments.
What to Specify When Ordering
- Quantity — the number of transformers for your electrical machines lab.
- Variable supplies and other machines — a three-phase variac or the single-phase transformer from the list below is a separate item that can be quoted on the same enquiry.
- Tender and shipping details — tender reference, destination and any packing or labelling requirements.
Frequently Asked Questions
What does the delta-star connection give?
The primary windings are joined in delta and the secondary windings in star. The star side has a neutral point, and the secondary line voltages are shifted in phase from the primary ones — the arrangement used in most distribution transformers.
What does insulation Class B mean?
It is a thermal class: Class B insulation is rated for a higher maximum winding temperature than Class A or Class E materials.
What terminals does it have?
Educational-type Bakelite-insulated banana terminals rated at 30 A, with a colour code marked on the top of the transformer and on a 6 mm Bakelite sheet, plus an earthing terminal.
What should an export enquiry include?
The quantity, the destination country and the port or city of delivery, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions and the tender reference with its specification.
Who manufactures this transformer?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electrical machines, electronics and science laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This transformer is built at JLab’s own works, not bought from a trader, so engineering colleges, ITIs, dealers and importers order from the maker and return to it for repeat orders. JLab exports worldwide and ships to buyers in every region — for example Ukraine in Eastern Europe, Oman in the Middle East, Namibia in Southern Africa, Spain in Southern Europe and Sudan in North Africa. Tender details are on the JLab lab tenders page.
