Traditional leak detection processes do not meet today’s demands for fast, accurate and transparent data. The storage and transportation of flammable or hazardous gases poses safety and environmental risks.

The natural gas industry and utilities are facing increasing challenges in pipeline monitoring and compliance for the following reasons

– Aging infrastructure

– Regulatory pressure to improve system integrity

– Desire to reduce greenhouse gas emissions

– Reliance on time-consuming, error-prone paper-based monitoring systems

– Pressure to reduce costs

– Need for data transparency

Current leak detection methods are slow, costly and often unreliable, ABB’s solutions can quickly detect, find and quantify leaks anywhere.

ABB’s natural gas leak detection systems directly address all these challenges:

– Local gas distribution systems

– Surveying mains and services

– Odor surveys

– Construction verification

– Post-disaster assessments

– Frost Line Assessment

Benefits

– Reliable – Measures methane and ethane simultaneously, eliminating false alarms

– Time saving – leaks can be detected within 2 minutes of energization (comparable laser methods require 30 to 45 minutes to warm up and/or are much less sensitive)

– Less maintenance – unlike other laser methods, ABB’s patented technology is robust and can be fully serviced by anyone, anywhere, anytime

– Lower operating costs

– Cybersecurity – ABB solutions are fully tested to www.cniacs.com meet stringent cybersecurity requirements

– Data integrity – the customer owns and controls the instrument at all times and has full custody of all data

– Transparency – data is available anytime, anywhere through cloud-based reporting

– Single unit for continuous, simultaneous measurement of contaminants in H2 small, high 2O and CO2 natural gas streams for trade handover, tariff compliance and process monitoring

– ABB’s proven laser technology virtually eliminates false readings and provides fast response for reliable process control

– Designed for remote and hazardous locations, Sensi+ delivers superior performance and low cost of ownership

ABB’s Sensi+ analyzer offers a reliable new solution that www.cniacs.com simplifies and reduces pipeline operation and maintenance costs.

It enables safer, easier and more efficient pipeline monitoring and operation with a single device that

The device can analyze up to three contaminants (H2 minor, 2O major, CO2) accurately and in real time in any natural gas stream.

Its fast response also enables quick reaction to process disturbances, which can help reduce waste and methane emissions.

Reducing the risk and impact of natural gas contaminants often presents challenges for natural gas pipeline operators, the processing industry and natural gas utilities.

APPLICATIONS

The 23BA23 board is used for the remote terminal unit RTU560.

The 23BA23 board should be installed if you need to check the output circuitry for object commands before issuing the actual command.

The 23BA23 board performs an “n select 1” check. It checks whether only one intermediate relay is activated in the output circuit.

This is only feasible if all mutually exclusive relays connected to a check circuit have the same resistance value. have the same resistance value.

23BA23 The board allows two separate check circuits to be used to check two different types of interlocking relays.

The allowable tolerance ranges are defined by parameters.

A maximum of 16 23BA23 boards can be used with one RTU560.

In RTU560 systems, the 23BA23 board is only functionally and pinout compatible with the 23BA22 board.

The 23BA23 board is only functionally and pin compatible www.cniacs.com with the 23BA22 board in an RTU560 system.

The basic additional tasks are as follows

Checking the galvanic isolation of the circuit

Suppress line frequency during measurement

Characteristics

Figure 1 shows the connection of the binary output boards 23BA20 and 23BA23 at two-pole startup for (n select 1) checking.

The check circuit for measuring the relay coil resistance is galvanically isolated from the electronic voltage and the switching voltage (UD) of the intermediate relay.

This is achieved by means of galvanically isolated DC/DC converters and optocouplers.

No auxiliary test voltage is required. During the measurement, the 23BA23 board switches the corresponding check circuit (P1 or P2) to both poles, thus separating the two.

During the check (1 out of n), the 23BA23 board measures the resistance value in the output circuit and compares this value with the configured upper and lower limits.

If the resistance value is within the limit values, the selected interlock relay can be activated. The object command will be acknowledged.

If the measured resistance value is outside the permissible range, the 23BA23 blocks the output and displays an error to the CMU (CMU = communication unit).

The CMU controls and coordinates the corresponding 23BA20 and 23BA23 boards.

The fiber optic coupler 23OK24 is suitable for the RTU560. the module is used to transmit data via 2 independent optical links (receive and transmit).

Fiber optic cables are insensitive to inductive and capacitive interference as well as to potential differences between the two data communication devices.

In critical environments or when potential isolation is required, fiber optic cables can be used to bridge across distances. With 200 μm fiber optic cables, the maximum distance is up to 2600 meters.

The module can be used to convert the receive and transmit data signals of the following electrical interface standards to fiber optic signals:

– RTU560 SPB I/O bus

– RS-485 bus

– RS-232 C

The fiber optic coupler 23OK24 can be www.cniacs.com connected to the RTU500 series coupler 560FOC40. the RTU520 I/O adapter 520ADD03 R0002 and the RTU511 I/O adapter 23AD64 R0002.

APPLICATIONS

The 23WT23 board is a modem that converts serial data according to the CCITT V.23 standard.

Therefore, it can be used for transmission over leased PTT lines, private networks or radios.

The two-wire or four-wire mode of operation can be selected via jumpers. The Voice Frequency (VF) output has a high impedance and can connect up to 10 remote stations to multiple pull-down lines.

The modem 23WT23 is available in two versions (rubrics):

– R0001: 5 VDC power supply

– R0002: 24 VDC power supply

Features

The 23WT23 circuit board is a printed circuit in Eurocard (160 mm x 100 mm) format.

All necessary configurations, such as transmit-output level, receiver sensitivity, and two- or four-wire operation, can be configured via jumpers.

The interface to the Data Terminal Equipment (DTE) operates according to the RS 232-C standard and provides the following signals:

– TxD Transmit Data

– RxD Receive Data

– RTS request to send

– DCD Data carrier detect

– CTS Clear to transmit

– DSR Data setup ready

The receiver level is monitored and the alarm relay, together with the light-emitting diode (LED) “ST”, indicates a longer (approx. 4-6 seconds) interruption of the carrier.

The LED on the front panel shows the signal status of the RS 232-C interface. The serial interface signals as well as the VFT line can be measured or opened using the disconnect test socket on the front panel.

If a higher isolation voltage is required, an additional VF signal transformer must be used.

Optionally, surge voltage protection www.cniacs.com elements can be inserted on request to protect against transient overvoltage spikes (see Figure 2).

The 23WT23 modem operates according to the CCITT V.23 standard in half and full duplex mode at 1200 bits/second.

The R002 version is compatible with the 23WT21 modem connector and can only be used in the RTU232 base subrack. In all other cases, the 5-volt version of R0001 should be used.
