There are two types of connections in three phase systems. One is a delta connection where there is no connection to ground, so you should not get any voltage to ground. This is classed as a three phase three wire system. In this type of system any one of the phase wires could become grounded and no one be the wiser. Code requires that grounding lights be added to a delta system to visually show what the phase condition is in relationship to ground. The other type of system is a wye or star point connection. This is classed as a three phase four wire system. In this type of connection the coil ends are all joined together and grounded. You would have voltage between the phases and a lower voltage to ground. The voltage to ground would be the phase voltage divided by 1.73.
Yes. If there is no voltage between a hot and a ground, either the hot isn't really a hot or the ground isn't really a ground.
AnswerThere is always a potential difference between a line conductor and ground, regardless of whether it is a three-wire system or a four-wire system. This is due to the capacitance between line and ground.
What else can I help you with?
What is the voltage measured between a ungrounded star point of a 3ph motor and ground should it be zero?
The voltage measured between an ungrounded star point of a three-phase motor and ground should ideally be zero. This is because, in a balanced system with no faults, the star point (neutral) does not have a potential difference with respect to ground. However, if there's an imbalance or a fault condition, the voltage could differ from zero, indicating potential issues in the system.
How do you wire a 110 V DB board from a 220 V 3 phase transformer supply?
In a wye system the voltage between any two wires will always give the same amount of voltage on a three phase system. However, the voltage between any one of the phase conductors (X1, X2, X3) and the neutral (X0) will be less than the power conductors. For example, if the voltage between the power conductors of any two phases of a three wire system is 220v, then the voltage from any phase conductor to ground will be 110v. This is due to the square root of three phase power. In a wye system, the voltage between any two power conductors will always be 1.732 (which is the square root of 3) times the voltage between the neutral and any one of the power phase conductors. The phase-to-ground voltage can be found by dividing the phase-to-phase voltage by 1.732 answer from ground and any phase
What is the voltage to ground of 13800 volts line to line?
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
What voltage is 1 leg of 4160VAC?
In a 4160VAC system, the voltage of one leg (phase) is measured as 4160 volts between that leg and the neutral point in a wye configuration, or between that leg and the ground in a delta configuration. However, the phase-to-phase voltage is 4160V, meaning each leg carries the same voltage when measured against the other phases. If you divide the line-to-line voltage by the square root of 3 (approximately 1.732), the phase voltage in a wye system would be about 2400 volts.
What is the measured Voltage between L1 and Earth on 3 phase system?
Wouldn't this depend on the voltage of the system? Like if it is a 460 or 208v system it would be 208 or 460v. There should be 3 lines L1 L2 and L3 all measure the input voltage. The wye or star point voltage on a three phase system is the square root of three. This number (1.73) is divided into the three phase voltage to get the voltage to neutral (ground). 208/1.73 = 120 volts, 415/1.73 = 240 volts, 480/1.73 = 277 volts, 600/1.73 = 347 volts.
Should there be voltage between the neutral and ground?
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
What is the voltage measured between a ungrounded star point of a 3ph motor and ground should it be zero?
The voltage measured between an ungrounded star point of a three-phase motor and ground should ideally be zero. This is because, in a balanced system with no faults, the star point (neutral) does not have a potential difference with respect to ground. However, if there's an imbalance or a fault condition, the voltage could differ from zero, indicating potential issues in the system.
What is the significance of the neutral to ground voltage in electrical systems?
The neutral to ground voltage in electrical systems is important because it helps to ensure the safety of the system. When the neutral to ground voltage is at the correct level, it means that there is a proper connection between the neutral and ground wires, which helps to prevent electrical shocks and fires. Monitoring and maintaining the neutral to ground voltage is crucial for the overall safety and functionality of an electrical system.
Should there be power from common to ground in wall socket?
120 volt wall outlets. Their could me a small voltage between neutral and ground,up to around 1.5 volts. What you are measuring is the voltage drop on the system at that point in the system. You see the neutral and the ground are at the same level some where up stream (service panel). The neutral is under the same load as the phase conductor, and the neutral will drop voltage same as the phase. This is in fact the way I measure voltage drop, (neutral to ground.) However don't get fooled by high imped. meter, They have a way of ghosting a voltage. Or floating high, You get a reading but the voltage is really not their.

IF YOU HAVE A 277 volt circuit IN you go from PHASE 1 to ground what will your voltage be?
In a 277-volt circuit, if you measure the voltage from Phase 1 to ground, you should read approximately 277 volts. This is because 277 volts is typically the line-to-ground voltage in a three-phase system where the phase voltage is 480 volts. Therefore, when measuring from the phase conductor to ground, the voltage remains the same at 277 volts.
What is the voltage value between one leg of a 208 volt system and the ground wire?
Well if you are talking about phases, it would be half of 208V.
What is the voltage to ground of 13800 volts line to line?
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
How do you test a motorcycle stator?
To test a motorcycle stator, first, disconnect it from the motorcycle's electrical system. Use a multimeter to check the resistance between the stator's terminals; it should match the manufacturer's specifications. Next, test for shorts by measuring the resistance between each terminal and the stator's ground; there should be no continuity. Finally, perform a voltage output test by starting the engine and measuring AC voltage at the stator terminals; it should produce voltage within the specified range when revved.
Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltageCorrection to the above answer:There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.
What is the voltage-to-ground on a 4160 V delta circuit?
There should be no voltage to ground on a delta system. That is the reason that these types of systems have to have a set of grounding lights to warn when the system inadvertently grounds. A delta system is a three wire connection, no neutral. A voltage to ground is only available on a three phase four wire (star or wye) connection system. The fourth wire being a neutral which is grounded thereby giving a voltage from each leg to neutral.
