Insulation

Measurement

Residual

Charge

Eect

Once

a

high

resistance

insulation

material

has

been

charged

with

a

voltage

,

the

material

will

continue

to

have

a

residual

voltage

across

it

for

a

while

after

the

charging

voltage

is

removed.

So

,

when

you

want

to

measure

high

resistance

materials

after

they

have

been

charged

once

,

wait

long

enough

for

the

residual

voltage

to

discharge

or

the

measurement

value

will

be

incorrect.

How

long

you

must

wait

depends

on

the

characteristics

of

the

material,

the

charge

voltage

level,

and

the

voltage

level

to

which

the

material

must

discharge

to

before

starting

the

measurement.

Absorption

Phenomena

When

a

high

insulation

resistance

material

is

charged

with

a

voltage

for

a

long

time

,

the

resistance

value

of

the

material

will

increase

.

So

record

the

time

from

the

start

of

the

pre-charge

to

the

start

of

the

measurement

when

measuring

and

comparing

samples

of

a

material.

The

pre-charge

time

should

be

consistent

from

sample

to

sample

.

The

resistance

value

of

an

insulation

material

is

measurement

voltage

dependent:

the

insulation

resistance

of

most

insulation

materials

increases

,

as

the

measurement

voltage

is

increased.

The

resistance

value

of

the

insulation

material

is

dependent

on

the

ambient

temperature

.

F

or

the

,

measure

the

DUT

while

it

is

in
