This PC based VI is a test & measurement instrument for conducting Instantaneous (magnetic) trip test on circuit breakers as per IEC 60898. The VI is designed in LabVIEW primarily for factory automation of the test process. Also, there's a 'Type-Test' mode for laboratory tests. The type test measures more parameters than the normal mode of test. The test sequence is fully automatic and ensures total operator safety. The VI utilizes a SCR ELEKTRONIKS high-current source for current injection. This VI is completely designed in LabVIEW and runs on a standard PC with Windows or Linux.
These are a set of virtual instruments designed in LabVIEW to run on a Windows PC or a Real-Time PAC. They make a complete and fully automatic SCADA system for test on electrical contactors as per IEC 60947. These VI take highly accurate measurements, collect all the test results securely in test database (RDBMS) and provide for reports including yield calculation, pareto analysis and daily/monthly production reports in various formats. The SCADA supports secure web based supervisory control and monitoring. In case multiple of such SCADA systems are used with many equipments inside factories at different geographical region, all the DUT parameters and test data can be stored and collected respectively on a web server. Supervisors can set alarms and triggers on events, such as an e-mail alert on low yield.
This PC based VI is a measurement instrument for plotting the Time v/s Current characteristics of a circuit breaker as discussed in IEC 60898, UL 508 and various other standards. The VI is designed in LabVIEW primarily for use by design engineers to optimize the design of circuit breakers at test laboratories as well as for certification purpose by assessment agencies. The VI runs on a standard PC and uses an electrical test setup for circuit breakers made by SCR ELEKTRONIKS. This VI is completely designed in LabVIEW and and can check all curves of the circuit breaker.
Thermal-trip test sequence in the time current characteristics' plotting process is shown in the above VI
This PC based VI is a production test equipment for Thermal Calibration & test of MCCB as discussed in IEC 60947, UL 508 and various other standards. The VI is designed for use by manufacturers of Molded Case Circuit Breakers. The VI utilizes a customised test bench and associates every breaker with a barcode for life-time traceability. It controls test current & other parameters, conducts simultaneous tests on multiple breakers and executes multiple test sequences automatically as programmed by the supervisor.
This VI provides for user management with multi-level security.
This PC based VI is a production test equipment for Short-circuit trip test of MCCB as discussed in IEC 60947, UL 508 and various other standards. The VI is designed for use by manufacturers of Molded Case Circuit Breakers. The VI utilizes a customised test bench and associates every breaker with a barcode for life-time traceability. It controls short-time high current & other parameters, conducts simultaneous tests on multiple breakers and executes multiple test sequences automatically as programmed by the supervisor.
This SCADA is designed to conduct thermal calibration of multiple Molded Case Circuit Breakers of same or different ratings simultaneously by a single operator. The HMI is designed to accomodate expansion of the test system, as and when required. The control system VI, that works with each current source & corresonding measurement devices, is controlled using the HMI thus providing the operator to conduct simultaneous thermal calibration of circuit breakers on a single test bench!
This PC based SCADA enable quality & performance testing as normally required by quality control department, assessment agencies & certification bodies. The software eliminates the labor of setting parameters for testing devices, generating reports & other meticulous tasks that the quality engineers otherwise have to manually work for each test job.
The above screen is the general look & feel of the SCADA for Quality Test. There's an energy saver-mode that puts the test bench in stand-by, all devices off & screen blackened to save energy.
SCADA guides the operator to do the appropriate on-bench connections for each Quality Test.
Once the connections are done, the SCADA calls the appropriate VI and picks up the corresponding quality test parameters from the test database. The above VI performs insulation resistance test.
The above VI performs the hipot test.
For each quality test, the control & measurement devices are selected & fed the programmed parameters first and then the test is conducted automatically. This helps to achieve user safety, lesser fatigue and speed. The above VI conducts power factor & on-load test on a ballast and measures the Total Harmonic Distortion and other set measurements.
Test laboratories and quality controllers often enforce report format to print & view test results. The below are extracts of report format for luminary test by a leading manufacturer. The SCADA has a dedicated module that generates reports in the desired format directly.
The above is a programmed template that eliminates the need to make reports manually after the test results are obtained.
Electrical Safety testing is the most widely implemented test process world-wide; being a mandatory assessment in most countries enforcing safety standards such as CEI 60335 for all devices that utilise electricity. This PC based VI automates the electrical safety test, using a SCR ELEKTRONIKS make Safety Test Equipment. This VI is completely designed in LabVIEW and runs on a standard PC with Windows or Linux.
