PRODUCT DESCRIPTION

The ISA CBA 3000 is the ultimate all-in-one circuit breaker analyzer: safer, faster and more accurate than ever. It allows any timing test, motion and speed analysis, multiple contemporary static and dynamic contact resistance measurements, Both Sides Grounded (BSG) tests, Undervoltage condition test and more.

All these functions are integrated in a single lightweight test case without the need of connecting additional external modules.

ISA CBA 3000 Key Features:

  • Faster: one single connection set up to perform automatically all possible Circuit Breaker tests
  • Safer: Both Side Grounded feature without any additional external boxes/modules
  • Three/Six/Nine static and dynamic contact resistance measurement – 200A DC output each
  • Three phase first trip measurement
  • 16 or 24 fully user configurable Main/PIR and auxiliary input contacts
  • 2, 4 or 6 Open / Close coil commands
  • 3 analog linear/rotary transducers and 3 digital transducers inputs for travel/ speed analysis
  • 8 analog input measurements: battery voltage, motor current, pressure transducers and other measurements
  • Minimum voltage trip coil test, fully automatic
  • On-screen control and test results evaluation
  • TDMS software suite for analysis, archiving and test report creation
  • Library of standard test plans available with the test sets

The ISA CBA 3000 is Capable of These Testing Functions and Offering these Features:

Test set control: via large 7 “ colour display. In this way it’s possible to select the test plan, perform all tests, analyze the results, zoom in and out the graph. A number of function keys and keypad plus selection encoder give full control of the test set. USB and Ethernet interface for communication with the PC are provided.

Capability to transfer results directly to an USB pen drive. Huge recording capability: more than 256 Mb (typically 1000 results).

All possible Test Plans are programmable. A Test Plan Editor is available in the test set while a Test Plan Library is supplied with the CBA 3000. The selected test plan includes all the operations that must be executed on a circuit breaker: Timing, Travel, Motor Current and Static and Dynamic Contact Resistance tests.

16 contact inputs (optionally 24) totally configurable. Each contact can be programmed as main breaker contact / PIR (Pre Insertion Resistor) or Auxiliary Contact. In this way it’s possible to verify a breaker with up to 8 breaks per phase. If a contact is programmed as Main, it is provided the measurement of the time delay and optionally the value of the pre-insertion resistor (PIR).

Two, four or six coil commands (Open / Close) are available in order to control each phase (Open or Close) independently. Three different current ranges can be used to measure the coil current of each circuit.

Up to three/six/nine micro-ohmmeters, equipped with high current generators up to 200 A (each), are available in order to perform three phases static or dynamic resistance measurements of a breaker contact at the same time. Additional two micro-ohmmeters modules can be added to extend up to six or nine 200 A static or dynamic resistance measurements of breaker contacts.

Safe test with Both Side Grounded: CBA 3000 can perform Both Side Grounded test ( BSG ) of a breaker, measuring the main contacts timing even if both ends of the CB are connected to ground in order to enhance the safety.

Eight analog input measurement circuits totally configurable. Every input can be configured as:

  • generic AC or DC analog input up to 300V AC (or 420 V DC peak) for measuring standby battery or motor supply
  • low voltage measurement for motion analysis with transducers
  • low voltage measurement for pressure transducers
  • very low voltage measurement for current clamps with voltage output
  • very low voltage measurement for micro-ohmmeter function
  • generic voltage input for other purposes

One auxiliary relay output, programmable.

Optional additional external micro-ohmmeter module with three current generators up to 200 A to get up to 3 micro-ohmmeters. Up to two modules can be connected together in order to perform at the same time dynamic or static resistance measurements tests on a circuit breaker with up to three breaks per phase.

Optional external thermal printer, 112 mm paper wide.

Optional internal thermal printer, 58 mm paper wide.

Optional Minimum Voltage Trip coil module to verify the functionality of the coil commands circuitry when under voltage supplied.

Optional IEC 61850-8 interface for GOOSE publishing and subscription.
