INTRODUCTION
Product Overview
The CB Watch 3 system (often abbreviated as CBW3 in this manual) is a monitoring system
for high voltage circuit breakers. It monitors the following aspects:
▪Operation timing
▪SF6 gas leakage
▪Arcing contact wear
▪Coil circuits
▪Stored energy system (spring or pump)
▪Cabinet / tank heater temperature
A web server HMI is provided to both configure the system and review the data but various
communication protocols are also available to transmit the data to a Historian or another
software system.
Document Scope
This Operating Manual is intended to explain the various monitoring functionalities of the
CBW3 and how they can be used to monitor a high-voltage circuit breaker. All outputted
information is detailed as well as all the possible alarms that can be set. Communication and
system settings are also covered.
Please refer to the CBWatch3 Installation Manual for information on the various modules
and sensors comprising the CBW3 system. It provides all the necessary information to install
and connect them together and configure the system.
Important note: All the available CBW3 monitoring options are detailed in this Operating
Manual. Depending on which configuration has been purchased and installed, all the
functionalities described in this document may not be available.

SYSTEM DESCRIPTION
Modules
The CBW3 system is comprised of both modules and sensors. The modules include the main
processor module and the various I/O modules. They receive and process the signals
obtained from all the sensors.
For more detailed information, please refer to the CBW3 Installation Manual.
Figure 1 –CBW3 Modules
1 Power supply 5 AI8-2 Module
2 ProWatch Module 6 AI8-3 Module
3 DI16 Module 7 RTD8 Module
4 AI8-1 Module 8 DO16 Module
Sensors
Depending on your CBW3 configuration, various sensors are connected to the modules,
either directly or through terminal blocs. These sensors acquire the data from the circuit
breaker so that it can be received by the corresponding I/O modules and processed in the
main ProWatch module. Please refer to the Installation Manual for details on sensors.

MA-037 - CB Watch 3 Operating Manual v7.0 - May 2020 Page 11 of 118
Time Stamps
Accurate time is being maintained by the CBW3 using a Real Time Clock (RTC). This RTC
requires system power to run and is backed up by a supercapacitor in case of power loss.
Normally the CBW3 is powered by the same substation DC power that powers the circuit
breaker. DC power is battery backed-up at the sub-station level and is very rarely not
available. In other cases, the CBW3 may be powered by an AC supply which is less secure.
In the rare cases where the DC or AC supply fails, the super-capacitor comes into play to
maintain the CBW3 date and time for approximately 15 days.
If the power loss lasts longer than that, then the date and time in the CBW3 will be lost and
it will have to be reset either:
-Automatically, if time synchronisation using SNTP or IEEE 1588 has been setup and
configured in the HMI. This happens every hour by default.
-Otherwise manually, by someone resetting the time using the HMI
Keep that in mind. For more details, refer to the CBWatch3 Installation Manual.
Note that every 3 hours, the date and time is written to a file. If the system loses power for
longer than the super-capacitor can hold, the system will indicate “Warning RTC data
corrupted” in the system log. If no automatic time synchronisation has been setup, then
when the system restarts, it will take the last date and time written to that file as the correct
time, until someone changes it manually. It will indicate “system date adjusted from time
file” in the system logs.
This is better than the clock reverting to the past (“01/01/2007” is the default of the RTC
chip) and losing time continuity, but it means that you might think that the system is
recoding operations as normal, yet there is a 15+ day gap that has been erased… and the
dates no longer match the real dates. This is all recorded in the system log.
Finally, please remember that a loss of power will be indicated by the service alarm K2. See
Section 13.2 later on.

HUMAN MACHINE INTERFACE (HMI)
Introduction
The CB Watch 3 does not require the user to load a special software to connect to it and
access the information it captures. The CBW3 has a built-in web server and an integrated
Human Machine Interface (HMI) which is accessible from any web browser (Firefox,
Chrome, etc…). We do not recommend using Internet Explorer as it is the least compatible
browser and you may encounter some display issues with tables and graphs
The HMI lets the user configure the system, set alarms and visualise all the measured
parameters, the alarm status and the curves/graphs recorded in memory.
TCP/IP configuration
Before you can access the CBW3’s HMI, you must first configure your network adapter.
Open Network Connections by clicking the Start button , and then clicking Control Panel.
In the search box, type adapter, and then, under Network and Sharing Center, click View
network connections. And then click “change adapter settings”
Figure 3 –Network card configuration step 1
Right-click the Local Area connection and go to Properties. If you're prompted for an
administrator password or confirmation, type the password or provide confirmation.
Figure 4 –Network card configuration step 2

MA-037 - CB Watch 3 Operating Manual v7.0 - May 2020 Page 13 of 118
In the window, select IPv4 IP address settings and click properties.
A new window (as shown below) will appear:
By default, the IP address of the CBW3 is set in the factory to: 192.168.5.22
But your particular IP address will have been set during the installation process. We will
use the default IP address here, purely as an example.
To communicate with the CBW3, you will need to set your network adapter to another
address on that network, for example: 192.168.5.30
The last number (30 in this example) could be between 1 and 254, except for 22 (which is
the CBW3 address)
To do that, select “Use the following IP address” and enter:
-The IP address 192.168.5.30
-The sub-net mask 255.255.255.0
You can leave the DNS server settings blank.
Then click OK.
Figure 5 –Network card configuration step 3
Here is an example of a network connection layout. It is possible to have several CBW3
connected on the same network in a substation. Each CBW3 is addressed by using its own
unique IP address
Figure 6 –CBW3 network connections

MA-037 - CB Watch 3 Operating Manual v7.0 - May 2020 Page 14 of 118
Connecting to the CBW3
Normally the CBW3 is fitted with a Fibre Optic (FO) LAN connection SFP module with LC
connector. To connect directly your laptop to the CBW3 you should either go through a
FO/RJ45 converter, a FO/USB converter or replace the FO SFP module by a suitable RJ45 SFP
module (see picture below).
Warning: Most standard 1Gbs RJ45 SFP modules will not work! Only certain 100Mbs SFP
module actually work. Please contact GE to acquire a correct and tested SFP module.
Figure 7 –Connection to the CBW3
Alternatively connect onto (or VPN into) the same network as the one the CBW3 is on.
Launch any Internet browser, “Google Chrome” in this example, (but preferably not
“Internet Explorer” which is old and has compatibility issues) and enter the CBW3’s IP
address in the address line.
192.168.5.22
Because the CBW3 uses “https” secure encrypted communication and your browser will not
recognise the SSL security certificate, it will give you a warning that the communication may
be dangerous and unsecured.
Figure 8 –Connection warning

MA-037 - CB Watch 3 Operating Manual v7.0 - May 2020 Page 15 of 118
Disregard and press the “Advanced” button which will reveal a “Proceed anyway” option.
Figure 9 –Connection advanced page
Please disregard the “unsafe” warning and proceed anyway to the IP address that you know
is the one you gave the CBW3.
Note 1: Depending on the browser used, it may be possible to save the IP address into your
browser and tell it that it is trusted so that the message will not appear next time.
Note 2: It is also possible to upload your own official secure SSL certificate into the CBW3
(that your network will recognise) to avoid this error message. This can be done in the
”System/Upload” page under the “Security” section:
Figure 10 –HMI SSL upload
For more detail, please refer to the CBW3 Installation Manual.
You will then get to the CBW3 welcome page which will ask you for authentication:

Also in this Operating Manual, we will often (as in the example above) mask part of the page
displayed with a blue screen in order to focus attention on the relevant part of the page.
When changing any setting in the HMI, please note that before the adjustment of a
parameter can take effect, it first needs to be validated and stored by pressing the "Set" or
“Change” button in the corresponding sub-section.
Figure 16 –Set button example
Note that, while most changes will take place as soon as you press “Set”, sometimes the
system will ask you to reboot after a big change, or will do it itself.
In particular, it is essential to reboot the system after any major change like:
•Changing settings from spring to pump type
•Changing the IEC 61850 configuration (it will reboot twice)
