Intended use
The circuit breaker tester, DV Power CAT-H, is designed to measure the main contact timing of LV and HV circuit breakers with 1 interrupting chamber per phase. The obtained results are displayed in both numerical and graphical forms for easier onsite results analysis.The list of instrument applications includes:- Measuring the timing of the main contacts (1 break per phase) including pre-insertion resistors (if present) and auxiliary contacts.
- Measuring the resistance of the pre-insertion resistors (if present).
- Evaluating the synchronization between the circuit breaker chambers.
- Coil Control for actuation of circuit breaker’s OPEN and CLOSE coil.
- Pre-trigger time measurement
- Evaluating the state of the substation’s battery.
How to Use CAT-H?
Both Low-voltage and High-voltage circuit breakers with 1 interrupting chamber per phase can be tested with the CAT-H Handheld tester. In case the pre-insertion resistors are detected, the tester will measure the ON Time and display the results.All obtained circuit breaker information including coil circuit data will be saved in a single test result file.Connecting CAT-H to a Circuit Breaker
The CAT-H tester is provided with test leads for measuring the timing of the main contacts and pre-insertion resistors, enabling the function to detect the state of the circuit breaker (Open / Close).Used Coil Control cable actuates the coils and simultaneously measures the current waveform of the corresponding coil with minimum noises from the environment. The Coil Control cable and Voltage Sense cable set can be easily connected to the coil circuit using the provided Dolphin Clips, Test probes, or Jumper cables.Similar models

DV-Win software provides acquisition and analysis of the test results. Graphical presentation of a variety of measurements and timing test results uses cursors and powerful zoom functions for detailed analysis. Colors, grids, scales and positioning of the test data are all controlled by the user. DV-Win supports an automatic unit conversion (e.g. cycles to seconds or mm to inches). The test records can be exported in .cath file format for further analysis.
DV-Win software provides:
- Downloading the test results from the CAT-H to PC
- Acquisition and analysis of the test results
- The test results can be viewed, edited, saved, printed and exported
- Viewing and overlaying several graphs, for an easy test result comparison
- Selecting the measurement points and intervals using the two cursors
- Zoom and pan graph feature
- Customized configuration of the test result graphs
