There is nothing more useful than a good, reliable data.Intuitive see you in charge of the assets of the whole system health, the value is immeasurable.Good data on assets can help you effectively controlled shutdown time, reduce the cost to the greatest extent.
Regular testing of assets such as motor, useful data can be accumulated for a long time.You can identify trends and planning system downtime, thus for maintenance or repair.Preventive maintenance is a kind of initiative methods, mainly based on the data collection and analysis.
Your team can from different perspectives and professional knowledge accumulation of data analysis, identify trends and issues, determine the next step, and to approve assets repair or replacement.If the whole team can access data, it is unlikely to happen unexpected shutdown event.
The motor insulation resistance testing
The motor winding insulation coating performance and wear over time will be reduced.One way to identify insulation performance degradation is analysis of leakage current data collected over time.When insulation performance degradation or damaged, the current will leak to the motor parts, causing serious wear and tear.Insulation to ensure correct current according to the design flow.
Motor insulation resistance testing focuses on capacitance and leakage current.Time than (sampling) used in testing insulation resistance testing, including polarization index (PI) and dielectric absorption ratio (DAR).Fluke insulation resistance tester automatically calculate PI and DAR, no additional Settings.Test data to identify current change in specific period, and then in the form of a ratio comparison.
For example, if 10 minutes after the current and current of the same after 1 minute, ratio of 1:1.However, this ratio is almost non-existent, because many other factors can influence the current circulation, including voltage and temperature.Due to the unstable voltage and temperature, so must be compensated, to determine the actual performance of insulation resistance.
Insulation resistance test data collected during at least include:
- Insulation resistance value
- Relative timestamp
- The test information
- The output voltage
- Test duration
- Temperature compensation
Importance of data
In this case, 雷竞技appa technician with a Fluke Connect ® technology of Fluke 1550 insulation resistance tester, the motor is tested, test its capacitance and leakage current.
- He quickly gather and save the data to the cloud server, is responsible for the system running time of maintenance manager by PC or laptop to view and analyze data immediately.
- Data collected over time suggest that the insulation resistance decreasing, or leakage flow.Once the data down to or lower than the preset minimum threshold, maintenance manager knew that motor needs to be maintained.
- The interface to select the timing of the least influence on the system's production for maintenance.
For these rec雷竞技appords, maintenance managers use Fluke Connect application generates a simple report, the program can display all relevant data of the motor.Report as a test to prove, and including the trend, easy to understand, very suitable for share with customers or device manager.雷竞技appFluke Connect to make data collection and analysis work more simple, drag and drop operation can generate a report.
The advantage of data sharing
To share data between stakeholders and experts team, means more effective preventive maintenance plan and open the system view, and easier to make decisions.
