The CHM ultrasonic height meter is designed to measurement power network conductor’s hanging in three-conductors configuration of the CHM300 type or six-conductors configuration of the CHM600 type. It works on principle of measurement the deceleration time between the moments of wave dispatching and reflection from a measured object. Maximum conductors hanging height is 23 m (for E model). To compensate environment temperature influence on propagation speed of waves, the instrument has been equipped with temperature sensor. It enables to automatically compensate temperature influence.
The AOUF-1/2 acoustic visual phase comparator is used for phasing in nets and alternating current devices 50 Hz and rated voltage from 3 kV up to 36 kV. It works in conjunction with UDI universal insulating pole with appropriate rating voltage.
The UTWN-1 universal tester of voltage detectors is designed for testing of all types, both low- and high voltage detectors manufactured by Wytwórnia Sprzętu Elektroenergetycznego „AKTYWIZACJA” in Kraków.
For the UTWN-1 universal tester, the voltage generation time is limited only by battery life span. It is suitable for testing the following instruments: electronic and optical voltage detectors, phase comparators, single- and two-poles voltage detectors of low voltage, e.g. WNN, and also gas discharge lamps, e.g. fluorescent lamps, neon lamps.
