 Circuit Breaker Operational Analyser with Dynamic Contact Resistance
Measurement HISAC Series |
|
| |
Universal CBOA to test all types of CBs LV, HV & EHV |
| |
Quick performance check of CB by measuring C, O, C-O, O-C & O-C-O timings with resolution of micro-seconds and selectable delay between multiple operations |
| |
Saves down time & number of operations of CB by testing all the critical performance parameters of all the poles / breaks in a single shot |
| |
Indicates pole to pole and break to break operation times for CBs having up to 4 main & 4 PIR contacts per pole, all 3 poles simultaneously |
| |
Simultaneity of operation of breaks and possibility of pole discrepancy can be assessed |
| |
Estimation of severity of condition of arcing tip through measurement of number & duration of bounces / chattering |
| |
Condition assessment of Auxiliary contact by measuring Auxiliary contacts timings (Wet & Dry contacts simultaneously) input for auxiliary contact setting to obtain specified C-O time |
| |
Condition of Close / Trip coils of all three poles monitored simultaneously |
|
 Minimum current required for CB operation point of plunger displacement |
|
Maximum current drawn by coil |
|
Duration of current passing through coil auxiliary contact cut off time |
| |
Analysis of Travel Characteristic with customised Travel Transducer cum Fixtures |
|
Velocity of breaker contact / mechanism of three poles simultaneously |
|
Velocity at the instant of make or break as well as velocity in between user
specified points |
|
Contact gap, contact wipe or insertion, over travel & rebound |
|
Condition assessment of the damping mechanism |
| |
Dynamic Contact Resistance Measurement for condition monitoring of the contacts without opening the interrupter |
|
Option for simultaneously recording DCRM signature of single or multiple (up to 6)*
interrupters |
|
Independent, isolated, inbuilt 100A DC sources for single or multiple (up to 6)*
interrupters still highly portable |
|
When DCRM signature is co-related with travel curve, the condition of main and arcing
contacts can be assessed and wear & tear of arcing contacts can be estimated |
| |
Monitor Station Battery Voltage (DC) |
| |
Measurement of ohmic value of PIR |
| |
Test results downloaded directly to PC/Laptop or hand held Memory Bank$ |
| |
Operation*, PC downloading, analysis & data manager software |
|
Self navigating, high level Graphical User Interface |
|
Programmable Test Plans* facilitating creation of Test Setup Library* reduces
testing time & involvement of valuable manpower |
|
Automatic creation of directory structure for storage of test data |
|
 Eliminates errors associated with manual data storage |
|
Easy future retrieval |
|
Trend analysis made easy |
|
Dynamic calculations on graphical information with cursor movement facilitating easy
on-screen analysis |
|
Multiple signature comparison and Trend analysis enables present condition assessment
and prediction of future performance |
| |
Comparison of test result with Manufacturers test result through programmable limit checks |
| |
Trend analysis enables a shift from schedule-based maintenance to Condition based, thus reducing outage required for testing |
| |
Easy to use self guided operation through interactive menu & keyboard$ or through PC with customized test plans* |
| |
Designed to work reliably under live EHV switchyard conditions ensuring operators safety and repeatability of results |
| |
Totally modular construction, conforming to DIN standard, offers expandability through addition of modules to meet testing needs of future* |
| |
Lightweight, housed in rugged aluminium case$ enhancing transport worthiness |
| |
Trolley mounted arrangement* facilitates easy movement within switchyard |
| |
Printing of tamperproof customized test reports |
| |
Supplied with test lead set having quick-fit connectors, suitable for EHV CBs |
| |
Can be ordered as CB Operational Analyser - basic version or with accessories/modules like customized Travel Transducer-cum-Fixtures, Dynamic Contact Resistance Measurement module, facility of PIR value measurement & Station Battery Voltage measurement etc. |
| $ Features available only in HISAC 2406. |
