1 INTRODUCTION
The circuit breaker analyzer and microOhmmeter model CBA2000 is a two-in-one test set.
When used as a circuit breaker analyzer, it allows the off-line testing of the characteristics of all
modern MV and HV circuit breakers. The test set measures CB operation times as they are defined
in the IEC standard 62271-100; in particular:
. Opening time: see 3.7.133;
. Closing time: see 3.7.136;
. O-C time: see 3.7.139;
. C-O time: see 3.7.143;
. Minimum trip duration: see 3.7.146;
. Minimum close duration: see 3.7.147.
When used as a microOhmmeter, it allows measuring the contact resistance of the circuit breaker
contact, or also of joints or other circuit parts. It allows also to perform the dynamic test of the
contact resistance, that is to record and display how does the contact resistance change while it is
closing: this allows detecting hidden defects, that are otherwise impossible to be diagnosed.
The instrument performs the following features:
Test set control: via keypad plus selection knob plus dedicated keys, and a large transflective LCD
display (320 x 240 pixels; view area 122 x 92 mm).
. Optional internal thermal printer 58 mm wide or external thermal printer 112 mm wide.
. Huge recording capability: 256 Mb (typically 500 results).
. Capability to transfer results directly to an USB pen drive
. USB and RS232 interface for data communication with the PC.
. Two driving coil circuits (O+C); 4 optionally available. The coil current is independently
measured on all outputs, with three current ranges.

the status of the circuit breaker is continuously monitored.
. Eight analog input measurement circuits, to be selected among the following:
- Coil current measurement: minimum 2, maximum 4;
- Two high AC or DC voltage measurement: up to 500 V DC or 350 V AC, for the measurement of
the standby battery or of the motor supply;
- Four low DC voltage measurement inputs, for the measurement of position transducers stroke and
speed, or of the pressure, or other low-level parameters.
. DC voltage source for potentiometer transducers polarization.
. One auxiliary relay output, programmable.
. Static resistance measurement; test current 200 A, 100 A or 20 A.
. Dynamic contact resistance test; test current 200 A, 100 A or 20 A.
. Many triggers can start the recording.
. Capability of generating or sensing a trigger, so that a number of units can operate at the
meantime.

. Test result is shown on the display: it is possible to analyse, zoom and so on.
. Capability of storing and recalling both test settings and test results.
. The software TDMS (that operates with WINDOWS 2000 up) is included: it allows analysing test
results, adding notes, saving into a data base and so on. It allows also to store and recall test
settings.
. The external option BSG1000 allows to perform the test when the circuit breaker has both ends
connected to earth, thus maximizing the test safety; it allows also to test circuit breakers with a
graphite nozzle.
All circuits have been designed to ensure safe operation in the noisy environment of HV and MV
substations.
The instrument is housed in a transportable aluminium box, that is provided with removable cover
and handles for ease of transportation.

When used with position transducers, the software allows the displaying of: positions, strokes,
speed (datum point). These measurements are defined by the position of the cursors. In this
instance, it is possible to input the transducer stroke, and to set the unit of measurement as
millimetres, degrees or inches.
When the transducer movement is 50% of the total transducer length, the position error is 1% of the
reading. The error is inversely proportional to the percentage of the transducer movement. When
datum points are 25% of the total transducer length, and the corresponding time is 10 ms, the speed
accuracy is 3%. The error is inversely proportional to the percentage of the transducer movement
and to the movement time.
. When used as analog inputs, the most important use is the monitoring of the secondary current of
an energized CB, to perform the first trip test, that is, the measurement of the Open delay while the
CB is in service. This test is very important to detect the delay caused by the friction, which sticks
the CB that has operated a long time without opening.
. Connection: three via three multi-pole connectors; the fourth one via a two-way shielded
connector.
. On the same connectors is available a polarizing voltage to supply linear position transducers.
. Voltage value: + 5 V; maximum output current 30 mA; minimum transducer resistance 170 Ohm.
The output has the same reference as the three low voltage analog inputs.
2.5.4 Digital transducers
The digital transducer input allows monitoring up to three digital transducers at the meantime.
. Maximum input frequency: 50 kHz;
. Interface: RS422;
. Accepted transducers: up to 5000 impulses per turn.
. Connection: by the same three multi-pole connectors used for the analog inputs.
2.6 TIME MEASUREMENT TRIGGERS
The following time measurement trigger options are user selectable:
. Internal: the time measurement starts as the first Open or Close coil command is issued by the
driving circuit. Timing accuracy: 50 µs.
. Coil current: the time measurement starts as soon as the first Open or Close coil current exceeds
the selected percentage, from 1% to 30%, of the selected current range.
. Auxiliary input: the time measurement starts when the selected auxiliary input turns ON or
changes its state. The trigger can be performed also on a logical combination of auxiliary inputs.
. Analog input: the time measurement starts when the analog input level crosses (greater than, lower
than) the selected threshold.
. External trigger. The test set features a Trigger Out output and a Trigger In input, that allow
synchronizing up to 4 CBA2000’s. In this mode, one CBA2000 acts as the Master unit; its Trigger
Out output will be connected to all other units, selected as Slave. As the Master starts the test, all
other Slave units will measure the timing on Main, auxiliary and analog inputs. Maximum timing
error: 100 us. This feature allows to test circuit breakers with more than two chambers per phase, or
to survey more than four auxiliary inputs, or to survey more than one analog input at a time.
2.7PROGRAMMABLE SEQUENCES
Shop for Power Metering products online at: 1.877.766.5412

Doc. SIE10169 Rev. 13 Page 11 of 32
The user can select the following Open and Close sequences:
. Open: the Open coil is driven. In case of four coils, the selected Open coil phase is driven.
. Close: the Close coil is driven.
. OC: In sequence, the Open and Close coils are driven. In case of four coils, the selected Open coil
phase is driven.
. CO: In sequence, the Close and Open coils are driven. In case of four coils, the selected Open coil
phase is driven.
. OCO: In sequence, the Open, the Close and then again the Open coils are driven. In case of four
coils, the first Open command is issued on the selected Open coil phase, while the second Open
command is issued on all coil phases.
Via the software, it is possible to repeat an OC or CO command up to 9999 times.
These sequences are also selected by means of a dedicated pushbutton; the selected sequence is
confirmed by an LED.
For all the above sequences, the user can program the following delays:
. Open command duration: range 10 ms to 10 s.
. Close command duration: range 10 ms to 10 s.
. Open to Close delay: delay range 10 ms to 199.990 s.
. Close to Open delay: delay range 10 ms to 199.990 s.
. Recording duration: range 10 ms to 199.990 s.
. After programming, it is possible to view on the display the sequence timing: this helps avoiding
programming errors.

test current passes through the contact, and CBA1000 measures the contact resistance variations
during the close movement.
. Test current, resistance ranges and other characteristics: as for the static resistance measurement.
. Unlike the static resistance measurement, the test result is not a table of resistance measurements:
it is the resistance profile during the test, along with voltage and current profiles.
2.10 TEST SET CONTROL
. The control is local, via keypad, selectors and display: no PC control is necessary.
. Keypad: 12 keys, numeric plus alphabet: it allows inputting all test references. The arrangement is
the same as portable phones.
. Two dedicated pushbuttons for test start and sequence selection.
. Numeric encoder with pushbutton for menu selection (see below the selections list).
. Five pushbuttons as menu shortcuts
. As the test is started, a buzzer warns the operator.
. The graphical display has the following main features:
-Type: transflective LCD;
-Pixels: 320x 240;
-Backlight color: white;
-View area: 122 x 92 mm;
-Displays: menu selections prior to test start; then, current waveforms, contact inputs (main –
resistance), auxiliary inputs, analog input (those enabled). For dynamic resistance, it is
possible to display the resistance profile, along with voltage and current profiles.
. Memory size: 256 Mbytes (approx. 500 results).
. Maximum record length: 200 s.
. Capability of saving and re-calling up to 64 test settings.
2.11 DATA MANAGEMENT
The communication to the PC can be performed via two communication ports:
. RS232; baud rate 57600;
. USB.
Test results can be saved into an USB pen memory: this allows transferring all test results to the
office without the need of transporting the test set.

item moving the knob. Once the item has been found and programmed, pressing the arrow the menu
moves back, so that other programming can be performed.
After test start, measurements are displayed in the corresponding window. Pressing the knob it is
possible to return to menu selections and modify them, and then it is possible to return to the
measurements window.
Any setting can be saved to and recalled from the memory, with a line of text description. At
power-on, the default one is displayed: it can also be recalled as necessary. Settings are permanently
stored in the memory; new settings can be written to the same address after confirmation. For
normal mode operation it is possible to recall the standard setting, that cannot be modified.
During the test, test results can be stored in the memory, according to selections.

3.11 SOFT PROTECTION BAG.
The soft protection bag hosts CBA2000 and protects it against dust and scratches.
3.12 DOUBLE EARTH TESTER BSG1000, CODE PII21166 .
The BSG1000 is an external module, that allows measuring the main contacts timing even if both
ends of the CB are connected to ground, for enhanced safety. The option solves also the problems
of wrong detections when the connection cables are subject to a rather high induced current.
Besides, if the Circuit Breakers has a graphite nozzle, CBA2000 displays the timing at which the
graphite is engaged, and when the main contact is reached, thus allowing to check the deterioration
of the graphite.
The options do not allow to detect the pre-insertion resistance, as it is shunted by the ground
connections.
Available options:
- BSG1000-1, for testing one break per phase (PII21166);
- BSG1000-2, for testing two breaks per phase (PII31166).
Each BSG1000 is made of the following elements:
. No 3 BSG Remote Heads, of different types, connected close to the main breaker contacts.
a) Remote Heads for BSG1000- type1 :
. Measurement circuits for one contact;
. Each head has two cables, 2.5 m long, cross section 4 sq. mm, terminated with crocodile clamps,
for the current injection.
. Each head has one bipolar shielded cable, 3 m long, terminated with crocodiles, for the open /
close detection of the CB contacts.
- Each head has one 8 m long cable, terminated with a multi-pole connector, for the connection
between the remote head and the BSG Main unit.
