# How we connect a analog ammeter for three phase current measurment upto 15 Amp. without CT with a rotery switch (Amp. selector switch)

Posted by on

Hi,
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
Good luck!

This is the car and truck section, so you may want to ask this in a different section.
You can only measure current as it moves thru a circuit. You can measure voltage in a contained space with a volt meter.

Current is the flow of electrons from positive to negative and the amount of current (amps) is the rate that electrons flow. Voltage is the pressure that makes the electrons flow. So you can measure the pressure(voltage) with you multimeter and you can measure the flow (amps) with an ammeter but you cannot measure what is not in the battery.( No flow)

### How to check current with phase tester

A phase tester does not measure current. You measure current with a clamp on ammeter.

### IF I SET UP AN AMMETER TO MEASURE CURRENT ENTERING BATTERY, WHAT WOULD I EXPECT TO READ

I wouldn't assume your figures, at (a nominal) 6v that puts the lamp wattages at 7.5 watts each, at 12V around 15W each, both very low.
Given your figures the total current is 2.4, but in the real world it would be around 7.5 to 8 amps with a 12V system.

### How do I switch the wiring for a Garland Model S 686 -2 Stove from Single Phase to 3 Phase?

If the oven is a three phase oven currently wired on single phase there will be three active terminals at the terminal block. There will be links or bridges which connect the single phase to each of these active terminals. Remove these links and connect each phase to each terminal.

### A voltmeter should be connected in a series with a component?

A Voltmeter is connected in parallel with a component because in voltage mode it has a high impedance and measures the voltage drop across the component being tested and does not affect any parts of the circuit.
An Ammeter on the other hand is connected in series with a component because in current mode it has a low impedance and measures the actual current through the component being tested

### How do you calculate low phase voltage of a three phase four wire system without useing voltmeter?

u can take three incadescent bulbs of same rating, connect them in 3 phase star connection, means 3 phase 4 wire connection..connect it across supply..the bulb connected across low voltage phase will glow dimmer than other two

connection would be easier in the wye. single phase current is easier to pull of of one leg in the wye to get your common that you would not have in a delta connection. three phase doesnt require a nuetral. just 3 phase 120degrees out of phase from each other

### My 2004 GMC Sierra 1500 has been losing battery charge

Try to locate the cause of the discharge current as below:-

While vehicle electrical system shutdown as for overnight storage, connect an ammeter (with suitable current capacity and sensitivity) across the main ground connection between the battery -ve terminal and vehicle chassis/frame - (-ve of the ammeter to -ve battery terminal post, +ve to vehicle frame),
Carefully disconnect the main battery ground cable from the chassis,
The ammeter will now measure the battery discharge current - a discharge current in the order of 0.5 amp or more is of concern.
If all is well, the current draw should not exceed 50- 100 mA.
Note- Do not switch on any load while ammeter is connected, as ammeter damage or overload will occur.
If an excessive discharge current is observed, remove all fuses etc to eliminate / locate cause.
