Hand Driven Generator Type

Application

'CIE' Earth Tester permits direct measurement of the resistance of earth used in power circuits. Telecommunication, Railway Electrification, Domestic & Industrial Electrical Installation, Lighting Protection Installation and various other Electrical Systems. The tester performs equally well in Terrain where the conductivity of the soil is low, e.g., in mountainous areas and in places where powerful stray earth current exist.

The four terminal instrument is specially designed for making straight forward and approximate soil investigation of the kind needed in agricultural, geological research and in the planning of large civil engineering projects such as tunnels, Drainage, Sewerage schemes, Tube-Railways etc.

Measuring accuracy of the instrument is not effected by stray alternating or back e.m.f. of earth electrolytic. The instrument can also be used for measuring non-inductive or non-capacitive resistance.

Durable, Portable Power Generation

This hand driven generator is engineered for reliability and ease of mobility. Its compact size (170 x 75 x 110 mm) and light weight (approx. 450 grams) make it highly suitable for field operations, emergency scenarios, and academic demonstrations. Shock and corrosion resistance further enhances its lifespan and usability, even in challenging environments.

Precision and Protection for Safe Operation

Built-in overload and short circuit protection ensures operator safety and device longevity. The generator accurately measures voltages from 0 to 30 volts, while manual operation allows for variable frequency (50/60 Hz equivalent). Its 3% accuracy makes it suitable for educational, research, or basic electronic testing.

FAQs of Hand Driven Generator Type:

Q: How does the hand driven generator operate without batteries?

A: This generator is manually powered by rotating a hand crank. It doesnt require batteries or any external electric source, providing immediate power generation as long as the user operates the crank.

Q: What is the voltage and frequency output range of this generator?

A: The generator can measure and provide a voltage output ranging from 0 to 30 volts. The frequency is equivalent to 50 or 60 Hz, depending on how fast the crank is turned by hand.

Q: When should overload and short circuit protection be utilized?

A: The protection system is automatically engaged whenever there is a risk of overload or a short circuit condition. This feature safeguards both the user and the device from potential electrical hazards during operation.

Q: Where can this hand driven generator be used effectively?

A: This device is ideal for use in laboratories, outdoor expeditions, educational settings, emergency preparedness kits, and wherever portable power generation is needed without electrical infrastructure.

Q: What process is involved in generating voltage with this device?

A: To generate voltage, simply rotate the handle at a steady pace. The faster the rotation, the higher the frequency output (up to a 50/60 Hz equivalent) and variable voltage within the specified 0 to 30 volt range.

Q: How does the generator benefit users compared to conventional power sources?

A: Its portability, independence from batteries, built-in safety features, and robust construction make it a practical choice for a variety of settings, ensuring power availability in remote areas or emergencies.
