Purpose: monitoring the currents of anode groundbeds, sacrificial anodes, and electrical jumpers on a per-channel basis.

The UKT board is made of fiberglass laminate, on which the elements of the electrical circuit are mounted.

Connection of conductors from anode groundbeds to the positive terminal of the cathodic protection station is carried out through the power block of the current monitoring device.

The device is produced in two versions:

• a power block with contacts for measurements;
• a power block with contacts for measurements and digital indication.

UKT devices of both versions allow current measurements in each circuit using a portable measuring instrument. In the second version, current can be measured by closing the measuring circuit of the indicator with a button mounted opposite the corresponding channel.

The UKT current monitoring device is installed inside the ICP.KMG post (Type P01, Type P02, Type 3).

You can order an ICP with UKSG in several modifications. The device can be installed in ICP types 1, 2, and 2B. The product package includes a special mounting platform. Using clamps, the unit is installed on the pipeline. A dielectric insert is mounted between the platform surface and the pipes, which completely prevents damage to the pipeline.

According to the ICP type, a special extension made of a metal profile is supplied. It is mounted on the platform. The length of the extension is individual for each order and can range from 1 to 2.5 meters. This parameter is calculated based on the depth of the pipeline in the ground. The price of the ICP with UKSG depends on the order parameters and additional equipment.

Formula for calculating the required extension length:

L_ext = A – B + C,

where: L_ext is the length of the plastic extension;

A is the depth from the ground surface to the top generatrix of the pipeline;

B is the depth of ICP embedding into the ground, equal to 0.7 m;

C is the height of the plastic extension socket, equal to 0.175 m.

Deviation from the axis of no more than 200 mm is allowed. The extension parameters directly depend on the type of inspection post. The posts are connected to each other using bolts included in the delivery set. In addition, UKSG can be ordered separately without an ICP.

Product Specifications

At the customer’s request, the device can be equipped with additional equipment. Delivery of the ICP and the package are discussed at the order stage. The product can be supplied in group packaging of 3 units or individually.

Scope of Supply

* Supplied upon additional order

You can order an ICP with a gas leak monitoring device for oil communications (ICP with UKG) for operation on high- and medium-pressure pipelines. The device is used to measure and monitor the air above the facility. The gas analyzer included in the set detects gas leaks and determines the concentration level in the air above the inspected pipeline. The device is equipped with a terminal board with clamps for connecting the cathodic protection system.

The housing of the unit is made of frost-resistant and non-combustible PVC. The post is seamless, one-piece drawn, with reinforced corners. The width of the product is 20 cm, and the length depends on the customer’s requirements. The manufacturer sets a minimum length of 200 cm. The price of the ICP model with a gas leak monitoring device depends on this parameter.

Product Specifications

The inspection post with UKG can be used in extreme temperature conditions. The minimum operating temperature is -60°C, and the maximum is +60°C.

Measurements are carried out using a portable gas analyzer.

The presence of additional terminals allows connection of sensors for monitoring cathodic protection system parameters.

UZT should be installed in locations with hazardous influence of AC sources from overhead and cable power lines with voltage of 110 kV and higher, as well as AC electrified railways, namely:

• along sections where the pipeline runs parallel to overhead lines (OHL), cable lines (CL), or electrified railways;
• at pipeline crossings with OHL, CL, or electrified railways;
• at points where pipelines approach or diverge from OHL, CL, or electrified railways.

Main functions of the AC drainage protection system:

• diverting AC induced in the pipeline by high-voltage power lines through the grounding circuit;
• preventing leakage of the CP protective potential, unlike standard pipeline grounding;
• measuring the diverted AC current via a transformer integrated into the unit’s circuit.

The UZT is a box housing the following components:

• a capacitor unit for diverting AC to the grounding device;
• surge protection device against atmospheric overvoltages (lightning protection) — gas discharge arrester;
• a transformer for measuring the diverted AC current;
• a frequency filter (standard version with 1100 Hz cutoff) to prevent leakage of AC of a fixed frequency when electrochemical equipment is installed on the pipeline.

Scope of supply

Stability is achieved by fastening the ICP post to pipelines with diameters from 100 to 1420 mm.

The UZK consists of a universal metal platform that is attached to the pipeline using clamps.

A dielectric insert is installed between the pipeline and the UZK structure to protect the pipeline insulation from damage.

An extension (the length of the extension is according to the Customer’s technical specification) is mounted on the metal platform on the upper part of the pipeline.

The extension is made of a plastic profile corresponding to the ICP type.

The UZK device can be supplied separately.

The measuring posts are made in the form of an elongated square or triangular post manufactured from durable, non-combustible material. The device housing features information markings and a panel for cable output and connection. You can order an ICP with UZZ with a cross-section of 20×1 cm in a square shape or with a cross-section of 18×1 cm in a triangular shape.

As grounding, the unit is equipped with steel strips. To achieve the required length, they are connected to each other with bolts and nuts. One section of the grounding strip is about 3 meters long and is determined individually in each case. The board with the electrical circuit is made of fiberglass laminate, and the operation of the device is regulated by a spark gap (varistor).

Product Specifications

Installation of the equipment is carried out in areas of possible exposure to sources of alternating current. The price of the product depends on the material used for the grounding device, as specified by the customer.

The device can be used at minimum temperatures down to -40 and maximum up to +40 degrees Celsius. Delivery of the ICP and additional configuration are discussed individually with the customer.

• where the pipeline runs parallel to overhead lines (OHL), cable lines (CL), and AC electrified railways;
• at pipeline crossings with OHL, CL, and AC electrified railways;
• at locations where pipelines approach or diverge from OHL, CL, and AC electrified railways.

The grounding device consists of horizontal and vertical grounding electrodes or a combination of both.

The horizontal grounding electrode consists of interconnected galvanized steel strips (sections) (40×4 mm, length 2 meters) laid in a line.

The vertical grounding electrode consists of interconnected galvanized steel rods (sections) (Ø16 mm, length 1.5 meters).

At the Customer’s request, the grounding device may be made of stainless steel.

The number of vertical grounding electrodes, as well as the number of sections in each, is determined by the design documentation.

You can order an ICP with BSZ for measurements and installation of equipment on pipelines located in hard-to-reach areas for maintenance. The equipment is made in the form of a square tube. The post is manufactured from a durable, impact-resistant, and non-combustible material. A terminal panel is installed on the surface of the post, and a digital ammeter is provided for current indication.

The built-in ammeter is activated by pressing a single button located on the control panel, which greatly simplifies operation of the device in any conditions. If one of the functional units fails, it can be replaced. The terminal clamps are made of steel with a galvanized coating. The unit itself has an anticorrosion protective layer. The price of an ICP with a Joint Protection Unit depends on the selected modification and additional order conditions.

The ICP can be installed in areas with harsh and extreme climates. To mark the installation location, the housing is equipped with a signal cap with reflective elements. The information markings on the post are abrasion-resistant. The terminal panel has a protective cover and allows connection of external measuring instruments. An agrotechnical coating can be ordered additionally.

Product Specifications

Installation and operation of the ICP fully comply with GOST standards. The minimum operating temperature is -60 °C, and the maximum is +60 °C.

The ICP with BSZ model can be used at extremely low and high ambient temperatures. Delivery of the ICP with BSZ and availability of additional equipment are agreed separately during order placement.
