Distribution Trainer (Product Code: SLE/EPS/02) is a two-panel electrical training system used to teach low-voltage and three-phase power distribution — feeders, loads, regulation, ring main and radial circuits — in power systems laboratories at engineering colleges, polytechnics and technical institutes. Its upper panel covers distribution basics with lamps and variable resistances, while its lower panel simulates industrial three-phase distribution using two three-phase transformers, one of which steps the line voltage down to 110 V. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Distribution Trainer Used For?

Students start on the upper panel, where a variable resistance stands in for a length of feeder cable and lamps act as consumer loads. Wiring the feeder as a radial circuit and then as a ring main shows why the ring keeps voltage higher at the far end and keeps supply going if one section is opened. Connecting the low-voltage AC supplies and changing load makes voltage regulation — the drop between no load and full load — something students can measure rather than just calculate.

The lower panel moves the same ideas to three-phase systems. One transformer brings the incoming supply down to the correct value for the experiments, lines carry power to the loads, and the second transformer reduces the line voltage to 110 V as the receiving-end transformer. Adjusting the primary tappings and earthing the secondary star point illustrates practical choices in real distribution networks, while the built-in current, voltage and power meters mean no extra instruments are needed for the core experiments.

What to Specify When Ordering

• Your incoming mains supply (voltage, phases and frequency), which is not stated in the listing.
• Bench or floor space for the two-panel trainer.
• Whether additional load banks or transformers are wanted for extended experiments.

Modular Power System (Product Code: SLE/EPS/03) is a power and interconnection hub used to join two or more power system training modules into one working setup in electrical engineering and technical training laboratories. Connected to a suitable mains supply, it powers each module, links their test circuits and ties every emergency stop into one safety network. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, within its engineering lab equipment in India range.

Key Details

What Is the Modular Power System Used For?

The Modular Power System hub is used whenever students work on more than one power system module at the same time. Instead of running long test leads across the bench, the hub carries the electrical test circuits between modules, so wiring stays short and each experiment is quicker to set up and check. This suits electrical engineering, polytechnic and vocational training laboratories that teach how interconnected power networks behave.

Safety is its second job. Because every module’s emergency stop button is linked through the hub, the lecturer decides with the keyswitch whether a stop isolates only the module where the problem occurred — useful when other groups are mid-experiment — or shuts down every connected module at once. Keeping the key with the lecturer stops students from changing that setting.

What to Specify When Ordering

• How many modules you intend to connect to the hub (it is designed for two or more).
• The mains supply available in your laboratory, so suitability can be confirmed.
• Which power system modules you already own or plan to add, so the links between them can be checked.
• Quantity required, for example one hub per bench or per lab.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Modular Power System. The hub is made and assembled at the company’s own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, not bought in from a trader, and is supplied factory-direct to engineering colleges, polytechnics, training institutes, dealers and importers.

The company is incorporated under CIN U29309HR2020PTC087597, and production runs under Factory Licence AMB-ONLINE-CHD-J-414. Replacement parts and repeat orders are handled by the manufacturer itself — just ask us. More about the company is on the ScienceLab company profile.

Power System Simulator Generator (Product Code: SLE/EPS/04) is a motor-driven generator console used to simulate a central power station feeding a transmission network in power systems laboratories. Electrical engineering students and trainees use it to study excitation control, prime mover speed and generator protection, with relays that operate real circuit-breakers — a core item of lab equipment for technical institutes. It is built by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Power System Simulator Generator Used For?

The simulator represents a second generating source — the kind of large central station, such as a main power station, that feeds the grid at transmission voltage. Linked to the Power System Trainer at that level, it lets students compare manual and automatic excitation control of generator output, vary motor speed through the vector drive and read prime mover and generator conditions on the digital meters.

Protection is the second half of the syllabus it supports. Students set the relays from their control panels, create the conditions that make a relay trip the circuit-breakers around the generator, and confirm the result from the breaker lamps. This shows how actual generators are protected and why different protection methods exist. For deeper work, the relays can be linked to a suitable computer for more detailed programming.

What to Specify When Ordering

• Whether you already have the Power System Trainer that the simulator links to at transmission level, or need both.
• Whether relay programming from a computer is planned, so the computer link can be discussed.
• The mains supply available in your laboratory.
• Quantity and delivery location (within India or export).

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Power System Simulator Generator.

Three-phase Mobile Transformer (Product Code: SLE/EPS/05) is a three-limb, three-phase teaching transformer used to demonstrate transformer theory and winding connections in electrical engineering and polytechnic laboratories. Its windings work at one volt per turn, so the no-load secondary voltage equals the number of secondary turns — something students can check for themselves. It is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and technical educational equipment manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Three-phase Transformer Used For?

Students use the Three-phase Mobile Transformer to explore transformer principles with values they can predict. Because each turn produces one volt, the expected no-load output of any secondary tapping is simply its turn count, so turns-ratio and voltage-ratio exercises are quick to verify with a meter.

With every tapping on its own shrouded socket, groups wire the primary and secondary windings to suit the experiment — including the common three-phase connections such as star and delta — and compare line and phase voltages. The wheeled steel enclosure lets one unit move between benches, or into a lecture room for demonstrations. Always isolate the supply before changing connections.

What to Specify When Ordering

• The input (primary) and output (secondary) voltages your experiments need, so the tapping selection can be confirmed.
• The three-phase supply available in your laboratory.
• Number of units: one per student group, or one for lecture demonstrations.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Three-phase Mobile Transformer. Each unit is made at the company’s own licensed factory in Saha, Ambala, Haryana, India, and sold factory-direct, so colleges, training centres, dealers and importers get quotations and after-sales answers from the maker rather than a middleman.

Thyristor and Diode Converters (Product Code: SLE/EPS/07) is a power electronics trainer used to build and study diode and thyristor rectifier circuits in electrical and electronics engineering laboratories. Students patch thyristors, diodes, inductors, transformers and smoothing capacitors together on a mimic-diagram panel, then compare gate pulses with output waveforms on the oscilloscope included with the set. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Key Details

What Are Thyristor and Diode Converters Used For?

This trainer teaches how AC is converted to DC — first with uncontrolled diode rectifiers, then with thyristor circuits whose output depends on when the gates are triggered. Students select single-phase or three-phase AC from the multi-tapped transformers, wire each rectifier circuit on the mimic panel, and measure currents and voltages on the analogue meters and the multi-function digital meter.

Two parts make classic effects visible: the load inductor shows how inductance smooths AC ripple, and the centre-tapped interphase transformer shows how circulating currents in rectifier circuits are reduced. Through the transducers, the included oscilloscope displays gate pulses beside the output waveform, whether triggering comes from the internal or an external source. A good habit is to start each new circuit at a low AC supply voltage, set on the lower panel, and raise it once the wiring is checked.

Portable Inductive Load Bank (Product Code: SLE/EPS/09) is a switchable inductive load used to apply reactive, lagging-power-factor loads to three-phase experiment circuits in power systems laboratories. Its three electrically separate inductor banks, housed in a robust steel enclosure, connect in star or delta and switch to give balanced or unbalanced loads. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and laboratory equipment manufacturer in India, at its own factory in Ambala.

Key Details

What Is the Inductive Load Bank Used For?

An inductive load draws current that lags the voltage, so this unit is how students create reactive power and a lagging power factor in a controlled, repeatable way. Switching inductors into each bank, they load a generator, transformer or distribution circuit and watch how current, voltage and power factor respond.

Because the three banks are electrically separate, the same load bank serves both star-connected and delta-connected experiments, and different switch settings per bank produce the unbalanced loads needed to study phase imbalance. Paired with a resistive load bank, it forms a mixed resistive-inductive load whose power factor can be stepped up or down during a practical.

What to Specify When Ordering

• The voltage and current of the circuits it will load, so suitability can be confirmed (ratings are not listed on this page).
• Whether you also need the resistive or power factor load bank for combined-load experiments.
• Number of units per laboratory.

OEM Manufacturer

The Portable Inductive Load Bank is an Ambala-made product: ScienceLab, the brand of Jain Scientific Equipments Private Limited, is its OEM (original equipment manufacturer) and makes and assembles it at the company’s own licensed factory in Saha, Ambala, Haryana, India.
