Drainage Protection Station NGK-SDZ for Effective Corrosion Prevention

Drainage protection station NGK-SDZ is designed to divert stray currents from underground steel structures to the rail chain, electrochemical protection of underground steel structures from soil corrosion, collection and processing of information on corrosion processes and anti-corrosion protection and transmission of this information via digital interface (RS-485/Fiber optic (VOLS)/GSM) to telemechanics systems. Also NGK-SDZ supports telemetering (TI), tele-signalling (TS), telecontrol (TC) and tele-regulation (TR) modes. NGK-SDZ allows monitoring of corrosion processes in one point - drainage point.

To increase the number of corrosion monitoring points (up to 32) it is necessary to use NGK-SCM subsystem. It is possible to increase the number of monitoring points by installing additional NGK-KSSM modules. The maximum number of monitoring points can be increased in multiples of 32.

NGK-SDS meets the requirements of GOST R 51164-98, STO Gazprom 9.4-023, "VTT to polarised electric...
