COMMON MISCONCEPTIONS IN ELECTRICITY

In the electrical sector, life moves several times faster than the usual pace. Therefore, electricians generally proceed by accepting the information provided to them by sales and marketing representatives as absolute truth.

This often leads to the circulation of many erroneous pieces of information in the market and unintentionally misleads the consumer, who is the benefactor.

Examples include suggesting a 0.5-1kVA regulator under the name of “combi boiler regulator” to a home user whose boiler constantly burns out due to fluctuations, or advising an industrialist with burnt electronic cards to purchase a massive Uninterruptible Power Supply (UPS), or recommending standard surge arresters against high voltage.

High Voltage Protection Products

Here are a few examples that can easily be multiplied:

• “Regulators protect against high voltage and overvoltages.”

A regulator is responsible for ensuring that the voltage stays within the necessary limits for a machine or device, limited to a range of approximately -90V to +50V.

However, high voltage or overvoltages are expressed in thousands of volts, and in such cases, regulators can also be damaged.

You can protect your regulator as well by using Trimbox new generation surge arresters.

• “Power supplies (UPS) protect against high voltage and overvoltages.”

A power supply is responsible for ensuring energy continuity in systems that cannot tolerate instantaneous power interruptions.

High voltage and instantaneous overvoltages can enter the system before the power supply can convert them to direct current; in fact, the power supply itself can be damaged in high voltage situations.

You can protect your power supplies as well by using Trimbox new generation surge arresters.

• “Surge arresters (SPD) protect against lightning, high voltage, and overvoltages.”

A surge arrester is responsible for conducting excess load to the ground to prevent damage caused by instantaneous overcurrents on the system, especially during lightning strikes.

A standard surge arrester does not perform surge suppression in cases of overvoltage or high voltage. In EN 61643-11 surge arrester pulse tests, it is checked whether the arrester itself is damaged while transmitting the load. Protecting a parallel-connected load in the system is not tested.

Trimbox new generation surge arresters have been presented by testing them with parallel loads at 15kV, 20kA 8/20 µs and 1.2/50 µs lightning current and voltage pulses, proving they protect the load as well.

• “If external voltage pulses are blocked, overvoltage-related failures will not occur in the system.”

There are two separate overvoltage formations in systems: external peaks and internal peaks. External peaks can be listed as lightning, physical problems occurring in transmission and distribution lines during windy weather, electrostatic air conditions, etc. Taking precautions against these is very important.

However, even more important pulses in systems are internal peaks created by the system’s own dynamics. These include peaks formed by induced voltage during power flickers, peaks occurring during inrush currents (demarage), robotic movements, etc.

Whether they are external or internal peaks, you can protect your electronic cards by using Trimbox new generation surge arresters.

• “Residual current devices (RCD) trip in case of neutral failure and protect against high voltage.”

An RCD is responsible for cutting the circuit in the event of a leakage at the 30mA level, which is the critical current value that can end human life.

An RCD has no function in the event of a neutral failure or high voltage. You can provide protection against the risk of damage from these situations by using Trimbox new generation surge arresters.

• “Fire protection relays prevent fires.”

The protection element known as a fire protection relay trips at a 300mA leakage and is responsible for cutting the energy.

Contrary to popular belief, it has no function in cases like cable overheating. In situations that can cause a fire, such as a neutral failure or phase-to-neutral contact, you can provide protection by using Trimbox new generation surge arresters.

• “You can adjust the neutral-to-ground voltage with an isolation transformer.”

An isolation transformer is responsible for ensuring that the operational grounding and protective grounding are completely isolated from each other.

The rise of neutral-to-ground voltage, which is usually desired at 1V, can happen for many reasons. With the GNDSeries neutral-to-ground regulator, the desired voltage value can be easily achieved.

Simple precautions sometimes save lives. The best investment we can make for our family, our business, and our environment is protective measures. With Trimbox and GNDSeries, you can be protected from electricity-related damages and electrical contact fires caused by them.
