    Ammeter Dc Test
AI Thread Summary
To test a 24V DC ammeter rated for 100A, connect it to a suitable power source capable of delivering the desired current, such as a car battery. A low resistance load, like a few feet of low gauge wire or a motor, can help generate high current levels, ideally around 25 or 50 amps. It's crucial to ensure the connections are secure to avoid any hazards during the test. The ammeter should be monitored closely to confirm it functions correctly within its specified range. Proper safety precautions must be taken when handling high currents.

How can i test an ammeter with ratings 24V (dc) 100 A with any load?
This is just to check whether the ammeter works in the defined range. What kind of source should i connect to get a current of maybe 25 or 50 amps.

You can generate high current with a car battery shorted, for a short time, to a low resistance load, such as a few feet of low gauge wire, or a motor.
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
