Electrical Power System Simulator
Product Code : LSK-EPS-10518
Electrical Power System Simulator (SKU LSK-EPS-10518), or PSS, is a laboratory model of a complete power network, from generation and grid supply through transmission lines and distribution transformers to consumer loads, with industrial-standard protection throughout. It suits B.Tech/B.E. power systems and protection labs. Universities, engineering colleges, tender contractors and distributors can source it through Science Lab Supplies, which quotes it from Ambala, India.
Specifications
The PSS table gives one feature per row. In short, a motor-generator set and a protected grid transformer feed separate buses, reactance-based lines carry power to two tapped distribution transformers and a utilisation bus with variable loads, and relays, breakers and meters cover every section.

Applications and Experiments for the Power System Simulator
With the simulator, students can run a small power system end to end: synchronise a generator, load lines and transformers, apply faults at chosen points and watch relays trip breakers, covering generation, transmission, distribution, utilisation and protection in one piece of engineering lab equipment.
- B.Tech power systems lab: generator synchronisation and choice of source.
- Load and power factor studies on the utilisation bus, a topic the Power Factor Load Bank also covers.
- Zone protection, grading, auto-reclose and directional tripping; single relay characteristics can be compared on the Protection Relay Test Set.
- Switching transients with the point-on-wave breaker.
Hazardous mains voltages are present; operate it only with trained staff.
Standard Scope of Supply
The simulator includes the motor-generator set, generator and grid transformers, transmission line reactances, two distribution transformers, utilisation loads with induction motor, switched busbar, industrial protection relays, circuit-breakers with lamps, blocking switches, two fault switches, meters, and an oscilloscope with transducers.
Packing, MOQ and Lead Time
The simulator can be quoted as one complete system, and further add-on modules from the range can be priced alongside it. Your quotation from Science Lab Supplies sets out packing, delivery time and price for the configuration and quantity you request.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. To configure a power systems laboratory, describe it on the contact page, collect modules in the enquiry cart, or check the lab tender page.
Frequently Asked Questions
Can students choose the power source for experiments?
Yes. Either the grid supply or the generator can act as the source, and the generator can be synchronised to the grid supply for realistic tests.
How are the protection relays set?
Students set the industrial-standard relays from their control panels, and each relay also has sockets for linking to a suitable computer when more detailed programming is needed.
Who supplies the Electrical Power System Simulator?
Science Lab Supplies quotes the complete PSS from Ambala, India, and can price it with add-on power system modules for a college laboratory or a tender package.
Can relay protection be overridden for experiments?
Blocking switches with warning lights let the user temporarily override relay protection at key points of the simulator, so extended experiments can be run under supervision.
