HISAC Ultima – Circuit Breaker Dynamic Test System from SCOPE. The ultimate solution for testing Circuit Breakers of all types. HISAC Ultima is the complete analyser for checking the dynamic performance of circuit breakers in live EHV switchyards upto 765kV.HISAC Ultima can carry out Dynamic Contact Resistance Measurement on SIX breaks of THREE poles in one operation thereby significantly reducing stress on circuit breaker & 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 circuit breaker by comparing present test data with previous test data and predicting future performance.

Key Features & Capabilities

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 test settings, graphical and tabulated test results
Prints test report in graphical format with test header and calculation footer, on external optional printer
Incorporates powerful Windows based Test Manager Software to control & operate instrument; view, analyse and handle graphical test data on a laptop at high resolution
Selects pre-programmed setup parameters and pass/fail limits through software
Connects to circuit breaker with wear resistant test leads of adequate 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 a variety of CBs

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
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 60068-2, IEC 61326-1 & IEC 61010-1. CE marked

Compact meter for photovoltaic systems up to 1000 VThe Sonel PVM-1021 meter is a compact photovoltaic system meter with a substantial number of measurement functions. The functions are selected with a rotary switch. Additional parameters are set with buttons located on the housing. All buttons and the graphic display are backlit, which greatly facilitates operation in shaded places, e.g. when taking measurements under ground-mounted PV systems. Large memory significantly shortens preparation of documents after the measurement.

Multifunctional analyzer EVSE-100 is an instrument dedicated to diagnostics of electric vehicle charging stations and cables. Using a single device, we will perform a set of tests on these objects, ending with the generation of a professional report. Through appropriate simulation of CP and PP circuits, the meter can put the station into various operating states. This allows us to verify the correctness of the control system and perform measurements in the field of electric shock protection. We can complete the verification of functionality and safety by simulating errors on the power supply side, i.e. the charging station (ICCB), and charging side of the vehicle (CP circuit)

The AR700 measures acoustic signals with multiple relocatable acoustic sensors mounted on the transformer. The software determines the defect location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer.AR700 device is used for measuring of acoustic signals on the external surfacesof gas-insulated switchgears, power transformers and other grounded tank high-voltage equipment.The acoustic signals are caused by partial discharges in the insulation, which is the site of the defects.The advantage of AR700 device is the quick installation of the relocatable acoustic PD sensors on the grounded external surface of high-voltage equipment. The sensors have magnetic holders thus making it unnessary to de-energize the equipment for the sensors installation.AR700 device has 4 synchronic channels for acoustic signal measurement. This gives the possibility not only to detect defects in the insulation, but also to locate them. The 3D location function of the AR700 device is unique for acoustic devices.

Battery banks have become an inseparable part of uninterrupted or back-up power supply arrangements in various industries like Power, Telecom, IT etc. In substations the critical protection, control & communication systems run on battery power. Hence the reliability of these battery banks is crucial to ensure smooth operation of equipment which they are serving. The capacity of battery may get reduced significantly before the expected life span of battery due to various reasons. The only way to assess the continual health of battery banks is periodical maintenance inspection & testing. Conducting a discharge test on batteries is most effective way to check the battery capacity.SCOPE introduces BLUe Series Battery Loading Units; these are moveble instruments for controlled & monitored discharge of batteries. They are designed for integrated site discharge test, design & QC test and also for monitoring discharge process of battery bank with connected load. Each single autonomous unit having built-in display, keypad and wireless communication with computer makes it very easy to use. It comes in different configurations ranging from 12V to 380V discharge voltages and 50A to 300A discharge currents.Various options are available to control & monitor the discharge process. With the help of optional Cell Monitoring Unit – CellMon, voltage of each individual cell can be monitored & data sent to main BLUe unit and then from main unit to computer via wireless communication. Each BLUe unit is supplied with computer downloading & analysis software for real time monitoring of discharge process.
