Pipeline systems and technologies

Construction description

The ICPD consists of a post, an AC draining unit, a terminal block and a grounding device.

1. Post

A post may be made of PVC or metal by the Client’s request. The post is equipped with an anchor device, which prevents a test station from free taking out the soil.

2. AC draining unit

AC draining unit contains the following devices:

  • a condenser unit for AC draining to the grounding device;
  • a protection device of atmosphere overvoltage (lightning protection) – a spark gap;
  • an electric transformer for drained AC measurement with 100:1 transformation ratio;
  • a frequency filter (a standard version with 1100 Hz frequency); to prevent AC leakage of a fixed frequency when using the electrometric equipment at the pipeline.

3. Grounding device

Grounding device may consist of horizontal ground conductors, vertical ground conductors or their combination. Horizontal and vertical ground conductors represented by sections of stainless steel or zinc plated steel connected to each other. Quantity of ground conductors and its sections number are defined by a pipeline system project.

As an option

As an option, ICPDs are produced with possibility to drain AC.
