what is the difference between megger and earth tester?..

Answer / mustakul

megger is an instument which in addition to measurement of
high resistance can be used to test the quality of the
insulation at or above its operating voltage.
whereas earth tester is used to measure low earth resistance

what is the difference between megger and earth tester?..

Answer / harish

Megger is used for measuring an insulation resistance of
motor winding of cable etc. which is measured in megaohm.
While earth tester has earth electrodes which are used to
measure eathpit resistance & it is measured in ohm.

what is the difference between megger and earth tester?..

Answer / jaseena

megger is used for measuring insulation resistance in mega
ohm range ,while earth tester is used for measuring the
earth resistance which is always less than 5 ohms ie a low
resistance

30 Yes

11 No

what is the difference between megger and earth tester?..

Answer / sunil guru

MEGGER IS USED 2 MEASURE D INSULATION RESISTANCE OF ANY
CABLE SO THAT ANY LEAKAGE BETWEEN THE INSULATION CAN BE
KNOWN AND MEASURES IN MEGA OHM...........

AND EARTH TESTER IS USED TO MEASURE THE LOW EARTH
RESISTANCE OF BETWEEN ANY TWO POINTS WHICH IS ALWAYS LESS
AND IN OHMS.............................

Is This Answer Correct ?

24 Yes

6 No

what is the difference between megger and earth tester?..

Answer / vinit patil

Basically Both are DC generators having different scales.
Megger measures insulation resistance on higher scale while
earth tester on lower.

what is the difference between megger and earth tester?..

Answer / jai

megger is used for measuring insulation resistance between
current carrying path (when supply is isolate) to ground
while earth tester is using for measured resistance between
two points of ground.

Is This Answer Correct ?

16 Yes

5 No

what is the difference between megger and earth tester?..

Answer / dipak

Actually megger is a brand name and tester called
insulation resistance tester which measure the Insulation
resistance and earth tester is measure the impedance of the
earth circuit.

14 Yes

5 No

what is the difference between megger and earth tester?..

Answer / vkn.1980@gmail.com

megger is used for measuring insulation resistance in any
ohm range 15 tera ohms ,while earth tester is used for
measuring the
earth resistance which is always less than 10 ohms ie a low
resistance

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
