Testing Tactics Webinar:

Cable Faults and How to Find Them

 

When:

10:00 a.m CT Friday, August 18

 

Attendees of this webinar are eligible to receive 
1 NETA CTD and either 1 PDH or 0.1 CEU

 

Underground power cables are in extensive use in almost all facets of the North American electrical grid. They are responsible for carrying electrical current over short and long distances, making them a critical element to the power system. Although power cables have a life expectancy of 20 to 30 years, the life of cable can be heavily affected due to typical stressors. Some of these stressors include manufacturing defects, poor workmanship, and extreme operating and environmental conditions. Any of these factors can cause a cable to fail while in service, leading to lengthy outages. Both pinpointing and repairing a faulted underground cable can be costly and time-consuming due to lack of access. Efficiently locating these faults helps to cut down customer downtime, maximize resources, and reduce the restoration cost.

 

Having the equipment to find these cable faults is not enough, understanding what your test set can do, understanding the test results, and the different techniques for finding faults is just as important. In this webinar we will cover how to approach cable fault finding and the different methods available for this process. We will cover time domain reflectometry (TDR), Arc Reflection Method, Current Impulse Method (ICE), and the Decay Method for cable fault pre-location. As well as, the use of cable fault locating (CFL) equipment, in conjunction with a shock wave receiver to quickly and efficiently locate a cable fault.

 

The purpose of this webinar is to discuss an effective fault-finding process, the different methods of cable fault finding, and the use of a shock wave receiver to help speed up the cable fault finding process. Understanding these topics will lead to greater understanding of the CFL process and in turn, decrease down time needed to find and repair the fault, thus leading to lower overall cost.

Robert Madarasz
Grid Performance Solutions Business Development Manager

I have 29 years of experience in direct sales, distribution and business development of Test, Measurment and Monitoring technologies for the Power industry. My current main focus is on Systems solutions for predictive maintenance and monitoring of critical assets in the power energy infrustructure. In my current position I am looking for building new partnerships in Europe and Africa with producers of power assets, with utilities, industrial customers with critical infrustructure, as well as service companies, interested in asset diagnostics and monitoring technologies.

My current key application areas are:

- Partial discharge testing and online monitoring of power energy assets throughout their whole lifecycle

- Smart Grid Sensors for Monitoring of MV distribution overhead line networks

An Evolution of Primary Injection Testing with the SPI4000

Circuit Breaker Webinar

An Evolution of Primary Injection Testing with the SPI4000

When:
2:00 p.m. CT Wednesday, September 13
 

Attendees of this webinar are eligible to receive 
1 PDH or 0.1 CEU

It is an accepted procedure that primary injection testing is crucial to the performance and reliability of electrical protection devices, such as breakers and relays. It is also important to test “through” the device to verify the full functionality of the protective scheme and not just “up to” the device. In the past, the feasibility of injecting a high current signal directly into the primary side of the breaker in the field was nonviable, primarily due to two reasons. One, the availability of a local power source to push a high-test current in the field, and two, the difficulty of transporting elephantine test equipment to the field. With the evolution of power electronics, the testing industry overcame the former, while the solution to the latter was limited to the frame size of the breaker. If the breaker had a larger frame size, high ground fault settings, or instantaneous trip current greater than 2000 amps, it became a hassle for technicians to transport their test set to the field. As for the asset owner, they had to choose between transporting multiple breakers to the shop or testing their protective scheme at a lowered trip setting.

 

This webinar will summarize primary injection testing processes with an emphasis on the Megger SPI4000 equipment. The presentation will delve into the state-of-the-art technology that enables the SPI4000 to achieve portability and transportability without sacrificing the need to test larger frame circuit breakers and substation protective schemes up to 40,000amps while using easily available power outlets in the field.

1 Hz Testing: A New Dawn in PF Testing

Testing Tactics Webinar:

1 Hz Testing: A New Dawn in PF Testing

When:
10:00 a.m CT Friday, September 22
 

Attendees of this webinar are eligible to receive 
1 PDH or 0.1 CEU

Power factor testing at 1 Hz has emerged as a new frontier in transformer maintenance testing, providing significant advantages over traditional methods. This webinar explores the benefits of 1 Hz testing, including its ability to detect and identify potential problems earlier and more accurately, leading to improved maintenance and reliability of transformers. This webinar also discusses the challenges associated with power factor testing and solutions to it. Additionally, the webinar presents case studies demonstrating the effectiveness of 1 Hz testing in identifying and diagnosing transformer issues. The comparison of the traditional testing at line frequency versus 1 Hz testing will also be emphasized to show how the complement. It will be seen how 1 Hz testing gives more predictive maintenance data to investigate insulation condition of the transformer as a whole and in the spot. In addition to this, bushings of the transformer can also be tested using this technology which will help schedule a planned outage to replace or repair as opposed to in service failure. This technique helps in minimizing the operation costs for the crews. in the field.
