Circuit Breaker Analyzer

Product Details:

Circuit Breaker Analyzer HISAC Ultima – new generation Circuit Breaker Dynamic Test Set from SCOPE …. The ultimate solution for testing Circuit Breakers of all types. HIASC Ultima is the most complete analyser for checking the dynamic performance of CBs in live EHV switchyards upto 765 kV.
HISAC Ultima can carry out Dynamic Contact Resistance Measurement on SIX breaks of THREE poles in one operation thereby significantly reducing stress on CB & testing downtime.
It offers flexibility to create pre-programmed Test Plans including all test settings for all types of circuit breakers available in a switchyard that can simply be recalled at the time of actual testing. This saves you from doing all settings in switchyards.
The Analysis software offers a range of utilities which enables effective Condition Monitoring of CB by comparing present test data with previous signatures and predicting future performance.

Features:

• Tests all types of circuit breakers - LV, HV & EHV for all critical performance parameters of all the poles / breaks in a single shot.
• Measures Main/PIR contact timings, bounce, non simultaneity of contacts and auxiliary contact timings.
• Analyses contact travel characteristics for speed, insertion, contact gap, over-travel and rebound with suitable transducer and mounting fixture.
• Records trip and close coil current characteristics.
• Registers the signature of Dynamic Contact Resistance of main and arcing contacts, of all the 6 breaks simultaneously.
• Displays settings, graphical and tabulated test results.
• Prints test report in graphical format with test header and calculation footer, on external printer(not supplied).
• Incorporates powerful and practical Windows™ based Test Manager Software to control & operate instrument; view, analyze and handle graphical test data on a laptop at high resolution.
• Selects pre-programmed setup parameters and pass/fail limits through software.
• Connects to CB with wear resistant test leads of sufficient length, having quick-fit connectors, suitable for EHV circuit breakers.
• Moves easily within switchyard as the set can be mounted on a specially designed Trolley having large wheels & mains supply distribution board.
• Travel – For evaluating travel characteristics of operating mechanisms, SCOPE offers rotary and linear resistive travel transducers with universal / specially designed fixtures to suit variety of CBs available.
• DCRM module captures dynamic variation in contact resistance of main & arcing contacts during breaker operation.
• Each DCRM module has in built independent isolated, rechargeable battery based 100A DC source.
• The result is plotted in graphical form on the software screen, which can be further analysed for finding parameters such as contact gap, total insertion, arcing tip insertion, main and arcing contact resistance values etc.
• Additional optional modules are available to measure PIR value and for monitoring Station DC (Coil voltage), Motor current or other static parameters through configurable Analog channels.
• Type Tested as per IEC 60068, IEC 61326 & IEC 61010-1. CE marked
• Supplied with suitable Test Leads & aluminium transport cases for instruments.
• Travel Transducer and fixture as per order based on make, type & rating of CB.

Product Details:

Circuit Breaker Operational Analyzer HISAC Swift - Circuit Breaker Operational Analyser is meant for checking the performance of the MV Circuit Breakers. The Analyser contains various intelligent measuring modules designed for measuring parameters such as contact timings of Main/PIR & Auxiliary contacts, Close/Trip Coil Current characteristics and Static Contact Resistance of R, Y & B poles simultaneously. The results can be directly viewed on the TFT touch screen display in graphical as well as numerical form. It is possible to print the graph on a built-in thermal printer or download record to PC for further analysis on CPLOT software. This all in one instrument is best suited for gang operated CBs.


HISAC Swift Circuit Breaker Operational Analyser HISAC Swift, the latest offering from SCOPE of its hugely popular HISAC Series circuit breaker testing solutions is an all in one test instrument designed to accelerate the performance testing of MV & HV CBs. It is housed in robust moulded case and has built-in colour touch screen display, thermal printer, memory & PC downloading facility. It combines the features of CB Analyser & Micro-ohm Meter and yet is very portable & light weight. It is designed to work under the hostile electromagnetic conditions prevailing in live HV switchyards. 


HISAC Swift is an ideal test tool for Utility maintenance engineers, Test & Commissioning engineers and engineers from industries that have large number of LV, MV or HV circuit breakeres ; and where shut-down time is limited and testing productivity matters. It checks, records & prints all important parameters like operation timings of main & pre-insertion resistor contacts, auxiliary contact timings, close/trip coil current and contact resistance of all 3 poles, simultaneously. It eliminates the need of carrying separate instruments for these measurements. Simple user interface through on-board colour touch screen display & smart connections ensures swift testing of various types of CBs. Though the instrument can be used for any configuration of CBs, it is best suited for gang operated CBs. 


Features:

• Type Tested as per IEC 60068, IEC 61326 & IEC 61010-1. CE marked
• Breaker information data entry and system settings entered into the kit through the touch screen keyboard
• Operations: C, O, C-O, O-C, O-C-O with configurable delays
• Contact timing of 3 Main and 3 PIR Contacts with 0.05mS resolution
• One internal channel to measure close and Trip coil current
• 3 multiplexed channels to measure Static Contact resistance with 0.1μΩ resolution and range up to 2Ω
• CPLOT software provided with instrument for further analysis on PC
• TFT Color LCD screen with touch, In-built printer, In-built memory for internal data storage
• Instrument housed in IP67 molded case

The Measurement:

• Proper functioning of CBs is of vital importance to ensure safety & availability of power network. These
• are expected to operate reliably & within specifi ed time limits in order to isolate the faults & save
• expensive equipment from stress or damage. In order to be assured of such consistent performance of
• CBs, periodical testing of important parameters is carried out. HISAC Swift is a smart & trusted tool for
• these measurements.
• TESTS all types of CBs - LV, MV & HV for all critical performance parameters of all three poles in a
• single shot, thus saving downtime.
