Description

The Portable NGC analyzes each sample utilizing established

chromatographic techniques. The resulting information

consists of mole percent values for the following:

• Air (N2 thru CO)

• C1

• CO2

• C2

• C3

• IC4

• NC4

• NeoC5

• IC5

• NC5

• C6+

• H₂S optional

The NGC8206 measures a C6+ (back flushed) peak. Users may

input the results of a comprehensive lab analysis that reflects

the split or ratio of C6 through C10 components. This ratio

can be used in subsequent analyses and energy calculations.

The NGC8209 measures a C9+ (back flushed) peak. Users may

input the results of a comprehensive lab analysis that reflects

the split or ratio of C9 through C12 components. This ratio

can be used in subsequent analyses and energy calculations.

Calculated values include

• Relative density (specific gravity)

• Btu/CV (heating) value

• GPM (gallons of liquid

The truck is moved as close to the sample point as is

practical. A flexible sample line is then uncoiled and attached

to the probe in the flowing natural gas pipeline. If the dew

point of the gas or the weather demands it, this flexible

tubing must be heated. A sample of the gas is extracted from

the probe in the line, purged through the flexible line and then

transported to the analyzer. There it is processed for particle

removal and phase integrity, injected onto the

chromatographic columns where component separation

occurs. These components are then quantified by peak

integration and concentration is calculated. The other data of

interest is then calculated from these concentrations.

The averaged output can be formatted to be accepted by a

3rd party gas accounting software system, allowing

automatic downloads of the analysis data. Analysis done on

site is valuable because:

• Transportation of DOT regulated gas cylinders is avoided

• Time and cost of subsequent laboratory analysis

• Problems with sample handling

• Economic solution for gas quality measurement when the

gas volumes are too low to justify on-line chromatography

Introduction

This data can be used for flow computers, RTU’s, gas

accounting systems, and SCADA systems for the energy,

AGA3. 7. 8. and 10 calculations at the meter site. This data

output can be a CSV file format so that analysis data systems

can easily incorporate the information. The number of runs

and the number of averages can be selected.

The RET670 also features pole slip protection, which detects and evaluates pole slips occurring in the

power system and takes the necessary action.

Sections of the power system that are swinging away from each other can be separated by

the line closest to the center of the power swing, allowing the two systems to remain stable when

separated.

The RET670 can be used with the IEC 61850-9-2LE process bus with up to six Merge Units (MUs).

Advanced logic functions allow user logic to be programmed with graphical tools to enable special

applications such as automatic opening of disconnect switches in multi-breaker arrangements, closing of

breaker loops and load transfer logic.

Logic can be monitored and debugged online in real time for testing and commissioning.

Communication via fiber optic connections ensures immunity to interference.

Six software packages are defined for the following applications:

– Transformer backup protection (A10)

– Voltage control (A25)

– Single-breaker, two-winding transformers (A30)

– Double-winding transformers with multiple circuit-breaker arrangement (B30)

– Three-winding transformers in single-breaker arrangement (A40)

– Triple-winding transformer in multi-breaker arrangement (B40)

The optional functions are not configured, but a maximum configuration with all optional

functions is available as a template in the graphical configuration tool.

Templates for alternative configurations for auto-transformers are also available.

The analog and trip I/O are pre-defined for basic use and come standard with one binary input module

and one binary output module.

The binary I/O can be added at the time of ordering, depending on the needs of the application.

the other signals need to be set up according to the needs of the different applications.

Trip and alarm signals from the pressure relief, Buchholz and temperature devices can be

sent directly to the RET670 via the binary input channels for alarm and standby.

The binary inputs are highly stable against interference and prevent incorrect operation due to,

for example, capacitive discharges in the DC system or DC ground faults.

The distance protection function serves as backup protection against faults within the transformer and in

the connected power system.

Positive-, negative- and zero-sequence overcurrent functions (selectable direction and/or voltage control)

provide further back-up protection.

Thermal overload, overexcitation, overvoltage/undervoltage and overfrequency/underfrequency

protection functions are also provided.

A circuit breaker fault protection function for each transformer circuit breaker allows high-speed backup

tripping of surrounding circuit breakers.

A built-in disturbance and event recorder provides the user with valuable data on status and operation

for post-fault disturbance analysis.

The RET670 can also be optionally equipped with a full range of control and interlocking features,

including a synchronization check function for integration of primary or local standby control functions.

The wide application flexibility makes this product

an excellent choice for both new installations and

the refurbishment of existing installations.

Six packages have been defined for the following

applications:

• Transformer back-up protection (A10)

• Voltage control (A25)

• Two-winding transformer in single breaker

arrangements (A30)

•Two-winding transformer in multi breaker

arrangements (B30)

•Three-winding transformer in single breaker

arrangements (A40)

•Three-winding transformer in multi breaker

arrangements (B40)

Optional functions are not configured but a

maximum configuration with all optional functions

are available as template in the graphical

configuration tool. An alternative for

Autotransformers is also available as a

configuration template. Analog and tripping IO

has been pre-defined for basic use on the, as

standard supplied one binary input module and

one binary output module. Add binary I/O as

required for your application at ordering. Other

signals need to be applied as required for each application.
