The first figure indicates the phase to neutral or ground voltage and the second is the phase to phase voltage. i.e. Vph-ph = 1.732Vph-n

How much volt apply to instrument cable meggering?
500v
When doing an insulation resistance test on an electrical circuit do you test at 500v dc or 500v ac?
dc insulation test = 2 * operating voltage +1000V ac insulation test = 2* operating voltage impedance of long wires or cables make ac testing sort of impractical dc test will never be lower than 1000V
How do you calculate arc length between electrode and charge in arc furnace?
Arc Length depends on the secondary voltage of furnace transformer. Thumb rule is for 500V the Arc length would be 500mm(20"). The purpose of arc length is to give maximum power to the melt, without arc flare. -
What is the current drawn when you have a single phased load of 200KW is supplied at 500v through an overhead line with a resistance of 0.1ohm per conductor?
If the voltage is 500 volts, and the power is 200 kilo-watts, then the current is 400 amperes. (Watts equals Volts time Amperes)The resistance of the conductor has nothing to do with this calculation, but that fact that the conductors are 0.1 ohms means that the voltage drop across each conductor is 40 volts. (Volts equals Amperes times Ohms) Since there are two conductors, the total voltage drop is 80 volts, and the voltage available to the load will be 420 volts.
A 100W 250 V 200W 250V is connected in series across a 500V AC which bulb will fuse first?
both will be fused.
What is the output voltage of an insulation tester which is required to test a 230v circuit?
On a hand crank megger which is used to test insulation breakdown, use the 300V setting. If the megger does not have that setting use 500V as opposed to 1000V for the test. The output of the megger is a DC voltage.

What will be the unloaded voltage if the primary is connected to 500V on a transformer that has 200 turns on the primary and 100 turns on the secondary?
If that is 500VDC, the secondary will have 0VDC. if that is 500VAC, the secondary will have 250VAC.

How many volts can a capacitor hold. what would be the formula for a capacitor that holds 100 volts?
The working voltage of a capacitor depends on the nature of the dielectric and its thickness. Most capacitors are marked on the case e.g. 500V wkg. or just 150V. Small components are colour coded; the code will tell you the capacitance, and the wkg voltage.

Can you use a 500V megger tester to test a 6.6KV motor?
You can, and you will get a reading if the leakage is within the operating parameters of the megger or there is a dead short in the windings. Most larger voltage motors need higher testing voltages. A hi-pot tester will deliver these higher voltages.

How do you measure insulation resistance?
Use a Mega Ohm meter, alaso known as a "Megger". Depending on the type of insulation you need to figure out what voltage to use. The test voltage can range from 500V to 5KV and you have to be sure you know what you are doing and use the right one....As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
