WHY DO DEVICE FAILURES OCCUR IN LABORATORIES?

PUT AN END to Device Failures in Laboratories!

The common problem of laboratories performing important measurements and analyses in many fields in our country is the damage to very expensive devices when systems are energized or at certain time intervals. Here, the issue can be listed as errors made in electrical design, neutral-ground voltages, poor ground resistance, harmonics, environmental magnetic field effects, and errors made in grounding type selection, rather than just lightning or sudden overvoltages.

However, it is a fact that there are many laboratories in our country that suffer from this issue and experience serious disruptions in their work. As Yılkomer, we identified problems in 12 large laboratories in 2018 and offered solutions in this regard. The subject involves the fundamentals of electrical engineering entirely, and precautions must be taken without allowing the devices to burn out.

In addition, in the analyses we perform, we see that residual currents are not applied correctly in laboratories, and protection measures against sudden overvoltage and lightning impulses are not taken at all. Millions of Euros flow abroad due to the perception of “I use UPS, nothing happens to my system,” which is one of the biggest misconceptions known as true in our country. Using UPS neither zeroes electrical faults nor prevents problems caused by lightning and sudden overvoltage. Making UPS grounding separately and grounding Laboratory devices separately is an application that invites devices to burn out even more. After providing the electrical infrastructure correctly and zeroing the voltage value between Neutral and Ground, the facility must be taken to full equipotential.

Reading voltage between Ground and Neutral is the most important reason for the failure of devices in the Laboratory. This voltage value needs to be minimized. As Yılkomer, we solve this problem completely in the works we carry out in Laboratories.

If we list the events causing Neutral-Ground voltage;

1- Unbalanced Load
2- Pulling power cables next to the grounding conductor
3- Equipotential Imbalance
4- Harmonics
5- Static Forces
6- Lack of Operational Grounding
7- Grounding Electrodes Design
8- Earth Leakage Currents
9- DC Sourced Systems
10- Load Sourced Problems

We can list them as above.

If we state the necessary precautions to be protected from lightning and grid impulses, we must definitely take protection measures with low voltage surge arrester systems. LV Surge Arresters with Strikesorb technology are the most correct precaution for laboratories with a 100% protection guarantee. Strikesorbs integrated in series into the system activate in 1 ns, and there is no chance of missing the impulse. The World’s most important science centers are protected by Strikesorb in this regard.

In conclusion, device failures and card burnouts in Laboratories are issues that have a solution; it is a subject that can be solved with correct engineering work. Systems should not be damaged in this regard. Our customers experiencing problems in this regard can contact us. First, we will identify the problem by performing measurement and analysis work, and then we will present the solution.
