HISAC Ultima The Product HISAC Ultima – new generation Circuit Breaker Dynamic Test Set from SCOPE …. the ultimate solution for testing Circuit Breakers of all types with both sides grounded.. HISAC Ultima is the most complete analyser for checking the compete dynamic performance of CBs in live EHV switchyards upto 765 kV. The portable analyzer is based on DIN standard modular and up-gradable 19”configuration having intelligent measuring modules controlled by an external laptop through an Ethernet link. The Ultima can carry out Dynamic Contact Resistance Measurement on SIX breaks of THREE poles...

SCOPE Dynamic Contact Resistance Measurement … DCRM signature • Advent of DCRM given condition monitoring of CBs a new dimension. It enables user to see what was not visible before…. Condition of main & arcing contacts, without opening the interrupter for physical inspection! • Change in micro-ohm values during C-O operation, as first the arcing & then the main contacts of moving and fixed contacts engage and disengage is plotted against time and a graphical record is obtained. For this DCRM+ injects 100A DC through contact assembly, reads the voltage drop at high sampling speed during this short...

HISAC Ultima HISAC Ultima Test Manager Software • Controls the operation of HISAC Ultima through laptop • Pre-programmable Test Plans facilitate creation of Test Setup library which is very easy to use & time saving during testing • User defined, structured storage of test data for easy future retrieval. Dynamic calculations on graphical information with cursor movement facilitating easy on-screen analysis • Comparison of test results with manufacturer’s test certificate using programmable limit checks • Assessment of present condition & prediction of future performance by multiple signature comparison...

SCOPE DCRM+ Modules for Dual Ground Testing (Optional) This test allows users to test the Circuit Breaker keeping it’s both sides connected to Earth. It captures dynamic resistance variation of Circuit breaker contact and also captures Circuit Breaker contact timing with bounces while CB is kept connected to earth from both sides. For this test two independent isolated DC current sources are provided of 100 Amps each. One module is capable of testing 2 breaks simultaneously. Three modules use at a time makes simultaneous testing of 6 breaks possible. Innovative hardware & testing arrangements...

HISAC Ultima Travel Transducer with Mounting Fixture In order to evaluate the travel mechanism / contact behavior of circuit breakers, it is necessary to mount the travel transducers at the appropriate point on the operating mechanism of CB. Depending on type of motion to be tapped either a rotary or a linear travel transducer having correct length as dictated by the stroke of circuit breaker is required. To hold this travel transducer rigidly on breaker mechanism suitable mounting fixture is required. This fixture is generally common (universal) for rotary transducers, however it may be custom...

Benefits Analysis of test results provides inputs to assess and correct: • Settings for Contact Timings • Closing and Opening speeds, over-travel, rebound and contact wipe • Auxiliary contact settings for obtaining specified C-O times • Trip/Close release mechanism settings • DCRM Signature gives information on: • Useful information on contact conditions, especially arcing contacts • Prior indication of deterioration in operating mechanism linkages • Certain mechanical weaknesses, undetected by travel measurement, are reflected in DCRM measurement.

Note : for dual ground mode using DCRM+ PIR value measurement is not possible • Breaker Control • Trigger Options • Sampling Speed • Plot Length : Three solid state contacts rated at 35A, 300V AC/DC for breaker operation (Close, Trip1 & Trip2) : Open, Close, C-O, O-C, O-C-O, delay between operations configurable. Command duration is also configurable : 20kC, 10kC, 5kC, 1kC selectable. Additional sampling speeds of 40kC, 0.4kC and 0.1kC are optional and can be provided on request. : 1 sec at 40kC, 2 sec at 20kC, 4 sec at 10kC, 8 sec at 5kC, 40 sec at 1kC, 160 sec at 0.4kC and 400 sec at 0.1kC...
