WEBINARS OLTC

VIBRO-ACOUSTIC METHOD APPLIED TO OLTC

Language: French, English, Chinese
Duration: 30 min of presentation and 15 min of open questions.

Description:

The vibro-acoustic diagnostic for OLTCs is a relatively new technology whose early development started about 15 years ago. It allows the execution of ONLINE and OFFLINE tests on any kind of tap changer and the prioritization of maintenance interventions thanks to its predictive approach, which consists in the analysis of the OLTC’s behavior over time (trending).

Seminar highlights:

    • Why / How / When to use the vibro-acoustic method?
    • Example of failures: wear of contacts, asynchronism, arcing contacts, etc.
    • Other applications: circuit breakers, voltage regulators and compressors

Who Should Attend?

This seminar will benefit a wide variety of organizations in the electric power and energy industries which will gain valuable insights into the vibro-acoustic method.

WEBINAR BREAKERS

VIBRO-ACOUSTIC METHOD APPLIED TO BREAKERS

Language: English
Duration: 30 min of presentation and 15 min of open questions.

Description:

Mechanical problems are the cause of 40% of major failures in breakers. Classical tests such as timing (or synchronization), motion (or displacement) and dynamic/static resistance of the contacts are often unable to detect this kind of problem. Vibro-acoustic method can, and this is the main contribution along with the possibility of performing online timing tests.

Seminar highlights:

      • Why / How / When to use the vibro-acoustic method?
      • What is the contribution compared to classical tests?
      • Example of failures in breakers: mechanical parts mounted in reverse, asynchronism (online and offline), bad adjustments.
      • Other applications: OLTC, voltage regulators and compressors.

Who Should Attend?

This seminar will benefit a wide variety of organizations in the electric power, and energy industries which will gain valuable insights into the vibro-acoustic method.

WEBINAR RECLOSERS

SIMULATION AND ANALYSIS OF RECLOSERS

Language: English
Duration: 15 min of presentation and 15 min of open questions.

Description:

webinar_recloser

Reclosers are small protection devices installed on distribution lines. Their control cabinets are programmed to react in certain ways according to specific protection curves. The GEN-X testers have been designed to simulate the mechanical part of the recloser (through internal auxiliary contacts) and verify the functioning of the control cabinet through injection of current and voltage.

Seminar highlights:

    • Why / How / When to use the GEN-X?
    • Main features of the software and contribution compared to classical equipments (Excel report).
    • Example of failures in reclosers: wrong reaction times on a Phase, wrong reaction time on the Ground.

CALIBRATION

Dear Customer,

In order to better serve you, Zensol has put together the 5 main reasons why calibration is of high importance for your instruments. Quality policies require it from us, government agencies regulate us on it, and international standardization bodies supervise us on how we accomplish it.

  1. Do you want to take measurements or estimates?

Electronic components naturally drift over time, which can lead to uncertainties in your measurements. Calibrating your instrument, prevents it.

  1. Can you afford to show inaccurate measurements on your products?

A. False Passes – Inaccurate measurements reveal a bad unit passing a test. A “false pass” can be very dangerous, especially if the product you are testing has the potential to cause damage.

B. False Failures – A measurement taken with a non-calibrated and / or inaccurate instrument may cause a test to fail at a good unit. These “false failures” may require more extensive (and expensive) testing and additional commissioning time.

  1. Do you meet the standards?

Many larger or more regulated industries follow international standards that require calibration. Standards such as ISO 9001, ISO / IEC 17025 dictate why and how to calibrate.

  1. Is unplanned downtime due to a non-calibrated instrument expensive?

It is important to keep in mind the difference between planned downtime for maintenance and unplanned downtime. Take advantage of the time your instruments are unused to schedule the calibration of your instruments.

  1. How do you know that your measurement is accurate?

By comparing all measurements to a standard unit, or to the international SI unit system, you can be sure that your measurement is a good measure. It is also important to respect the traceability of your calibration by reference to an uninterrupted and documented calibration chain.

Calibration is clearly an important part of proper maintenance of your measuring instruments. By regularly calibrating, you can save time and money and make sure you meet all the requirements of your profession.
