Locating Ground Faults

Jun 15, 2023 - Jun 15, 2023

 

1:00pm - 3:00pm US CST

This webinar will focus on locating ground faults in ungrounded DC battery systems. Various standards require action when the impedance between any battery polarity and ground falls below a specified limit. In the case of nuclear-fueled plants, the Nuclear Regulatory Commission (NRC) requires audits and appropriate action when this impedance is deemed unsafe. Other facilities come under the guidelines of the National Electric Code, NFPA, IEEE Standards, and OSHA requirements for operation of DC battery systems in an ungrounded environment.

Most failures of electrical equipment are the result of a breakdown in the insulation system. Power factor/dissipation Factor testing is an effective way to detect defective electrical equipment insulation. Power factor/dissipation factor is the ratio of the capacitive or ‘charging’ current (measured in volt-amperes) to resistive or ‘leakage’ current (measured in watts). It is a means of measuring insulation integrity since the smaller the loss angle, the better, or more efficient the insulator. 

 

Insulation may be deteriorating; however, the equipment may not fail for some time. Although this condition represents a serious hazard, if deteriorated insulation is detected before failure, it can often be reconditioned instead of being replaced. This allows corrective action to be taken during a planned outage before extensive equipment damage results from insulation failure. 

 

Power factor/dissipation factor testing also makes it possible to detect equipment insulation problems without making an internal visual inspection. The result is a significant decrease in maintenance cost and downtime.  Power factor/dissipation testing is one of the best testing techniques for predictive and preventive maintenance. 

Understanding Insulation Resistance Testing

Aug 17, 2023 - Aug 17, 2023

 

1:00pm - 3:00pm US CST

FREE - GoToWebinar

2.0 NETA CTDs

Preventative Maintenance Series

 

In this webinar, we will review insulation and its properties along with basic causes of insulation degradation.  We will learn how insulation resistance is measured and how an insulation resistance test set (megohmmeter or hipot) operates.  Proper use of an insulation test set along with various types of insulation tests will be reviewed and discussed.  Discussions will include potential sources of measurement error, environmental effects on readings and safety associated with the operation and use of a megohmmeter or hipot.

Understanding High Potential Testing

Preventative Maintenance Series

 

In electrical testing and maintenance, a dielectric withstand test (or pressure test, high potential or hipot test) is an electrical test performed on a component or product to determine the effectiveness or strength of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground. The test is a means to qualify a device's ability to operate safely during rated electrical conditions. If the current through a device under test is less than a specified limit at the required test potential and time duration, the device meets the dielectric withstand requirement. A dielectric withstand test may be done as a factory test on new equipment or may be done on apparatus already in service as a routine maintenance test. 

 

Tests can be performed with 50/60 Hz AC, DC, or Very Low Frequency (VLF) voltages. This webinar will explore high potential testing including where, when, and how we use the various styles of high potential tester.
