Application specific design 

Continuously variable voltage auto transformer, protected type. Comprises a torridly wound transformer with a continuously variable output voltage 0-260 volts AC. Steplessly under full load. Input 220 to 240 volts AC, 50 Hz. In stout metal case mounted on a metal base with mains cable.

A brass C.P. spring arm with press knob & two brass terminals. All mounted on bakelite base 80x55mm approx.

Under Voltage & Over Voltage Relay Trainer is designed for practical training in protective devices implemented on transmission lines, cables and network sections in high voltage power transmission systems. A Relay is an electrically operated switch and the basic working principle of a relay is an electromagnet which is used to operate a switching mechanism mechanically. Relays protect the power distribution system against continues voltage surges that can cause damages to motors and other electrical equipment. Our Under Voltage & Over Voltage Relay Trainer provides theoretical and practical experience to students by controlling, monitoring and analyzing individual relay settings and tripping characteristics.

AC and DC Starter Trainers are designed to explain the various concepts of AC and DC Starters. A motor starter is equipment used with AC and DC electric motors to temporarily reduce the load and starting torque. The various types of starters incorporated in our AC and DC Starter Trainer are Star Delta Starter, DOL Starter, Three Point Starter and Four Point Starter. The trainer kits are designed with an objective that students can acquire knowledge of all the basic concepts and working of starters efficaciously. . Circuit Diagrams are embedded on the control panel so that students can easily understand the internal architecture of AC and DC Starters Trainer.

Electrical Machine Laboratories are designed demonstrate the operational working characteristics of DC Shunt Generator under various loading testing conditions. DC Shunt Generator is a type of Generator whose field winding and armature winding are connected in parallel and generate characteristics to behave almost like a constant speed DC Machine. Our Electrical machine lab equipment can be used for conducting various experiments so as to analyse operational working characteristics of a DC Shunt Generator. Circuit Diagrams are embedded on the control panel so as to provide self guidance to the students for making the connections on their own.

A model of the simplest form of DC motor; having 3 armatures - 2 pole, 3 pole, & 4 pole, wound with enameled copper wire, & a permanent magnetic field provided by a removable bar magnet. The construction is completely open & all components are readily observable. A disc type commutator is incorporated & external connection to the phosphor - bronze bushes is by means of a pair of 4mm sockets. The motor shall operate on 4.5 to 9 volts DC.

Generation of AC , alternating current can be demonstrated using this dynamo generator model By turning the handle of dynamo model the current that is produced can be seen as it lights the lamp. The quicker the handle of demonstration dynamo generator model is turned, the brighter the light glows.

Mounted on a wooden base 125x250mm, all parts easily visible, rigid constructions to show the connections on a vertical stand.

Digital Meter for general purpose laboratory use housed in tough case use of a 3½ digit cover most of the ranges. Displays 13mm characters; operates on mains with accuracy ± 0.3% typical. Linearity 0.2% typical.

A simple demonstration of a Dynamo Model mounted on a wooden base of size 200x170mm. Hand driven by a gear. Simplified open frame construction which can be readily understood without detriments to its essential similarity to real machine. A 2 pole armature wound by enameled copper wire to rotate in U shape magnet in pivot. While in rotation process through the gear wheel by hand, the bulb provided glows.
