Railroad contact-line support testing device "PK-2"
The device is manufactured in accordance with Technical Requirements 427675-005-42376246-2004.
Certified in the System of Facultative Certification of Means of Nondestructive Inspection, No.05 03 074, registered in the Branch List of Means of Measurement Allowed for Application at Railroad Transport, No. МТ055.2005
It was designed for detection of electrocorrosion hazard of ferroconcrete reinforcement of contact-line supports of railroads with direct and alternating current. The device can also be used for checking and adjustment of protection devices.
Absence of influence of external noise on results of measurement
Significantly reduces the time necessary for taking measurements
Enables to test and adjust protection devices (spark gaps)
Eliminates unstable contacts in earthed circuits of contact-line supports and gives out reliable results even without a preliminary clearing of connection spots
In combination with the device "Poisk" used for detection of low-resistance contact-line supports in a group "PK-2" device enables to perform the whole complex of operations for estimation of electrocorrosion hazard of contact-line supports provided by "The instructions in technical maintenance and repair of contact-line supports K 146-2002"
Various modifications of the device have been supplied to power economy establishments of public corporation "Russian Railroad" since 1996.
