Description
The construction and operation of electrical devices and installations
require the compliance with certain safety precautions to protect
man. These safety controls are laid down in national and
international regulations and must be checked at regular intervals. All
safety controls are always based on insulation resistance
measurements. The requirements in practice vary a great deal,
however.
New regulations and increasing nominal mains voltages make ever
greater demands on the measuring engineer and his test instru-
ments. This has resulted an increasing number of areas of applica-
tion for 5000 V insulation meters.
The insulation measurement which, as such, is basically simple faces
multiple types of applications. The insulation quality of materials and
various objects also has to be tested for instance. Overvoltage
suppressors or other voltage limiting elements also have to be tested
for faultless functioning.
Despite all these requirements simple operation, high overload
capacity and protection against misoperation of the instrument must
be guaranteed.
The UNILAP ISO 5kV insulation tester is an expert for all insulation
tests and their applications.
The instrument meets highest technical requirements while covering
as broad an area of application as possible and complies with all
relevant regulations governing construction, safety and
measurement. Other insulation meters in this category can, at best,
provide an instrument with analog display whose size and weight do
not meet the wishes of the users. The UNILAP ISO 5kV on the other
hand features both an analog and a digital display and has been
fitted in the well proven UNILAP housing. We have thus managed to
realise the smallest and handiest 5kV insulation meter while
complying with all the criteria laid down in IEC 1010.
We used the most state-of-the-art technologies, such as microproc-
essor control and SMD components, for the construction.

Insulation resistance measurements with 250...5250 V DC from
10 kW to 30 TW.
Fixed measuring voltages selectable via central switch:
500V 鈥?1kV 鈥?2.5kV 鈥?5kV.
Variable range from 250 V to 5250 V in 10 V and 50 V
increments.
Determination of polarisation index and dielectric absorption ratio.
Polarisation index with freely programmable sampling times.
Continuous measurements with freely selectable interval.
Measurement of local insulation resistance with optionally
available probe.
Gradually increasing measuring voltage for insulation or
overvoltage suppressor tests with selectable start-, stop- and
breakdown-voltage, selectable number of voltage levels and
duration per level.
Free customer-specific configuration of basic settings via code
programming:
- display and setting of LIMITS with optical and acoustic warning
in case of upper or lower limit violation
(standard values are stored)
- blocking of an undesirably high insulation measuring voltage.
- default values for continuous measurements, overvoltage
suppressor tests or polarisation index measurements with
freely selectable sampling times can be stored.
Fully automatic user guidance as protection against misoperation
and damages.
Automatic display of the external voltage prior to measurement
and the voltage remaining applied after measurement.
Quick reference within sight.
With the optional (Docu-Pack or RS232) interface and the
WINISO5kV application software remote control of all functions is
possible. They can also be used for the individual configuration
(code programming) of the instrument.
Special accessories for measurements with GUARD technology
or local insulation.
