  • Micromilliohmmeter IKS-1A is available in two kits: “Basic” and “Energetic”

    Compact micromilliohmmeter IKS-1A is designed for rapid measurement of electric resistance to direct current, mostly of contact resistance of bolted and welded connections, sockets. The device allows measuring electric resistance of low-inductive and inductive circuits of machines and instruments in the range from 1 microohm to 200 Ohms.

    The device can also be used for controlling the resistance of metallic bonding to evaluate reliability of the contact between different elements, forming electrical ground.

    In devices produced since 2019, it is available the mode “AUTO Contact” which allows to start the continuous measurement process (when both hands are occupied by measuring probes).

    The device is available in two modifications: «Basic» and «Energetic» (see the Completeness tab).

    In the kit «Energetic» the device with extended functionality allows measuring winding resistance of transformers with the power of up to 1000 kVA in the electrical grids of 0,4-10 kV.

    In the kit «Energetic» the device with extended functionality («AUTO IND» mode) allows to measure the resistance of transformer windings with power up to 1000 kVA in electrical grids of 0.4-10 kV. In addition, the device in this kit is supplied with testing wires, 3 m long with “alligator” type clips with the grip width of up to 40 mm.

  • Microohmmeter IKS-200A

    While measuring electrical resistance of high current circuits (contacts of high voltage breakers and disconnecting switches, bolted and welded connections), it may be necessary to conduct measurements at the current comparable with the nominal one. In such cases it is most suitable to use Microohmmeter IKS-200A, enabling to measure low electric resistance with the measuring current of up to 200 A.

    Microohmmeter IKS-200A has internal batteries, what makes it possible to conduct a series of measurements without connecting to the network, the device is easy to operate and practically requires no maintenance. The device is placed into high-impact plastic case, bears impacts and rough usage.

    The device has Bluetooth interface, used for conducting remote start, viewing and saving measurements results into the memory with the help of a mobile device (smartphone or tablet) on ОС Android.

  • Three-phase volt-ampere phase meter VFM-3

    Volt-ampere phase meter VFM-3 is designed for simultaneous measurement of effective value of three phase and three phase-to-phase voltages, value of the strength of three alternating currents with simultaneous calculation of real, reactive, apparent power in the circuit, measurement of frequency and phase-shift angle between phase and phase-to-phase voltages, between currents and voltages, as well as for displaying a vector diagram of the voltages and currents in three-phase systems.

    The device has a built-in function of an electrical energy meter.

    The device can be used for complex tests of generators protection, transformers, electric lines, in current and voltage transformer circuits, in setting up phase-sensitive relay protection schemes, for checking whether electrical energy meters are connected correctly.
