2. THERMAWATCH STATOR TWS-100 SERIAL LINE SENSORS - INSTALLATION

2.1 Preliminary considerations

• TWS-100 is an array of sensors placed on aserial line, dedicated to real-time multipointtemperature monitoring, with individuallyadjustable alarm levels for each sensor.

• A typical serial line is comprised of a maximumof 100 sensors operating independently.

• On a standard serial line, sensors are setapart at 30cm (12in.) interval. Custom seriallines are available upon request.

• Several independent serial lines can beinstalled on the same generator, each with it’sown specific layout.

A record must be kept of each sensor location. This information will be needed during configuration of the associated ZOOM software. A copy of this ThermaWatch Installation form can be found at the end of this section (pages 12 & 13)

WARNING!

Installation of the TWS-100 Serial line sensors in the air gap can generate high voltagecreated by magnetic field. Consequently, the TWS-100 Serial line sensors should not beinstalled in the air gap, unless an in-depth analysis revealed that no voltage can begenerated.

WARNING!

Installation of the TWS-100 Serial line sensors on high voltage equipotential surfacessuch as end-windings is hazardous, and can cause electric discharge or shock as well asequipment damage.

Consequently, the ThermaWatch TWS-100 Serial line sensors must not be installed onend-windings nor other high voltage equipotential surfaces.

WARNING!

In an hydrogen-cooled environment, the use of silicone and PVC tubing must be avoided.


For stator core thermal mapping:

• TWS-100 serial lines must be installedon the outer side (back) of the statorwall only

• Several serial lines may be installed toform a matrix of sensors

• Sensors can be distributed horizontally,vertically, or placed in any arrangementsuited for maximal coverage and thermalmapping efficiency.

For stator winding temperature monitoring:

• TWS-100 serial lines are installed in astraight line on stator bars outside of thestator core, on the section with semi-conductive paint only.

• Each sensor is glued on any stator bar,close to the stator core. The cablebetween sensors must be glued to asurface.


2.2 Installation of the TWS-100 Serial line sensors

A clamp kit is added to complete the installation kit. Clamps are needed to secure the protective tubing andflexible conduit coupling firmly against the installation surface, and to make sure they remain flat and free ofvibrations.

2.2.1 Supplies needed• clean dry cloth and grease remover• a sensor installation kit including:

- glue (Loctite 330) and its activator (Loctite 7387) or equivalent

- silicone (3145RTV) or equivalent

• a clamp kit including:- 1” conduit clamps

- 3/8” conduit clamps

- ¼” flat washers

- ¼” spring lockwashers

- ¼ - 20 x 5/8” hexagon cap screws

2.2.2 Preparing the installation surface

After choosing the location where the sensors will be installed, clean the surface to remove oil and carbondeposits.

• It is imperative that the surface be thoroughly cleaned before the sensor can be glued onto it. This step must not be neglected as sensor adherence depends on the prepa-ration of the surface.


2.3 Installing the ThermaWatch Sensors

2.3.1 Glueing sensors1. Clean the back of the sensor with a clean dry cloth.2. Apply glue on the back surface of the sensor and spread to a thin and even coat.3. Spray the catalyst activator over the glue on the sensor.4. Position sensor on the clean surface. 5. Pivot sensor to spread the glue evenly, and then reposition vertically. Maintain in straight upright position

for 60 seconds or more.

2.3.2 Installing protective tubing and conduitTo prevent abrasion and degradation, all cables must be kept as free of vibrations as possible. In windingtemperature monitoring applications, where sensors are installed on stator bars, the use of a protectivetubing, 90° elbow, and flexible conduit is recommended to protect the cable as it runs on top of the stator core,through the windings, and as it exits the stator. Proceed as follows:

1. Determine the run of the flexible conduit, from thecommunication tapping box to the location of theelbow.

2. Assemble the elbow at the end of the flexibleconduit (refer to Figure 1 :“Elbow and protectivetubing assembly”).

Figure 1 : Elbow and protective tubing assembly

• The glue bonds quickly. Surface and sensor preparation must be completed before applying the glue.

• Handle glue with care, avoid skin contact.• Handle the sensor with care.• Never pull on the integral cable.


3. Drill holes for the conduit clamps (referto Figure 2 :“Cable clamp installation onsteel surface”).

Figure 2 : Cable clamp installation on steel surface

4. Secure the protective tubing and thecoupling (refer to Figure 3 :“Suggestedlocation for cable clamps”).

Figure 3 : Suggested location for cable clamps


2.3.3 Protecting bare cable with silicone or epoxy paste

Any exposed part of the cable must be glued and protected with silicone or epoxy, depending on the machine internal environment.

In any environment free of hydrogen:

To secure the integral cable and keep it from vibrating, glue the cable to the surface with a bead of silicone.Also apply a fine bead of silicone around the edges of each sensor, as this will prevent accumulation of dirtand particles around and behind the sensor and at the same time, help protect the sensor.

In an hydrogen-cooled environment:

To secure the integral cable and keep it from vibrating, cover the whole cable with a fiberglass adhesive tape(suggested: VibroSystM reference #34616) and impregnate it with epoxy paste (suggested: VibroSystMreference EP8117).

WARNING!

Do not apply silicone or use PVC tubing in an hydrogen-cooled environment.
