Test Equipment & Instrumentation, Hire, Sales & Technical Services LEM Unilap ISO up to 5kV Insulation Tester Home   LEM Unilap ISO up to 5kV Insulation Tester 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. The most important functions and advantages are: Insulation resistance measurements with 250...5250 V DC from 10 k to 30 T . Fixed measuring voltages selectable via central switch: 500V – 1kV – 2.5kV – 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.
