The ME Induction Load manufactured by us is a single phase and three phase variable induction load that is housed in a metal case provided with Castor wheels for easy handling. The instrument is used for varying current, which is measured on Ammeter(s).
When rotating knob is rotated in clockwise direction, the coils are kept in closed position.
When rotating knob is rotated in anticlockwise direction, the coils are kept in opened position.
The D.C. Shunt (or ME shunts) available with us are ideal for current ratings from 5 to 10000 Amps and mill volt drops of 75 millivolts. The product conforms to IS Standards 1248 and is provided with leads of 0.025 ohms. Some of its construction features are cited below:
It consists of Mangenin rods, soldered or silver brazed, to brass end blocks.
It is artificially aged after manufacture; followed by tests on full load.
Lead resistance is considered while calibrating the instrument
Salient features of the ME Shunts are as follows:
Class 1 accuracy
0.002% per degree centigrade, above ambient temperature in still air, with free ventilation
Temperature not exceeding 120°C at the center and 90°C at the ends
The ME Shunts withstand temperatures up to 120oC; without any permanent alterations in physical or electrical properties
Overloads and faults due to high temperatures (>120oC) can be safely handled
All 75 millivolts drop shunts of class 1, withstand the following overload requirements:
We manufacture and export high class ME Load Bank, which is a single phase and three phase variable Lamp or resistor or capacitor load and is housed in a metal case. It is used for stimulating load conditions to test Voltmeters, Ammeters and Watt meters, using load switches provided on the bench. The total simulated load is the sum of loads of all 'ON' switches. Construction Features: The ME Load Banks are provided with:
Castor wheels for easy handling
Ammeters and Voltmeter on front panel to indicate the current and voltage respectively
Heavy-duty Porcelain switches with bake lite top and inner brass contact for safety
