What is Lightning? How to Protect Instruments?

Entry pathway of lightning surgeDue to the online application of modern electronic systems, there are multiple interfacing parts to the outside for an instru-ment. One of such interface parts is signal cable and the other one is power cable. These cables pulled from the outside can be perfect entry pathways for the lightning surge.

The effects of induced surge on a connected device will be more severe when the connected cable is longer and the device is located closer to the place where the actual lightning strikes. Even lightning rods with minimal cable length do not always protect as they are hoped.

The effect of lightning surges depends upon the cable loca-tion and its environment. Surge protectors installed in those paths absorb and eliminate the high voltage impulse energy and protect the electric instrument from damage (Figure 1).

Breaking mode of electrical instrumentSurge voltage generated between a cable and the ground might reach several tens of thousands of volt, however, lightning occurs at a voltage typically five thousand volts between the cable and the ground, while it induces several hundred volts between lines.

When analyzing breaking condition of the instrument, it is often broken by this line voltage. We call it ‘interline breakdown’. Characteristics of interline breakdown is that semiconductor parts near the entry point of lightning surge breaks.

Also, breaking mode between the cable and the ground is called ‘discharge breakdown’. Because the lightning surge voltage is very high against that of the ground, an arc discharge is generated between an electronic circuit and a grounded enclosure. Characteristics of discharge breakdown is that weak part of insulation between the circuit and enclosure breaks down.

M-System’s surge protectors keep the surge voltage level at which instrument does not get damaged and prevent interline breakdown and discharge breakdown.

Interline breakdown (V1)This occurs when the surge voltage between cables is directly applied to the electronic components in the instrument. Usually, only these components that are located near the termination of the cable where the surge entered are destroyed.

Discharge breakdown (V2, V3)Lightning surges cause a very high potential (voltage) difference be-tween two conductors and the ground, and a discharge occurs between some part of an electronic circuit and those electrically connected to the ground, such as metal housings. Electronic components become damaged because some of the discharge current flows through the electronic circuit (Figure 2).

What is Lightning? How to Protect Instruments?

Fundamentals of surge absorbingInduced lightning is a current source which tries to flow the current. This current is the lightning surge current. When current does not flow smoothly, it generates high voltage and forces to let the current flow. The high voltage generated at that time is lightning surge voltage.

Now, let us explain the fundamentals of lightning surge protector. Here we explain them with an example of a most commonly used model, the MDP-24-1. The diagram below is a simplified circuit of the MDP-24-1. On the cable, lightning surge voltage V1-V3 is generated to let the current flow. We call V1, interline surge voltage, and V2 and V3, line to ground surge voltage.

The surge protector absorbs V1 at the discharge element SA1 and V2 and V3 in SA2 and SA3. SA1-SA3 can be considered as voltage-dependant switches. When the voltage is high, an arc is discharged and they suppress the arc discharge of V1-V3 around 30V. It is important to limit the surge voltage as low as possible. Especially, V1, which is applied directly to the protected instrument, is eliminated by the discharge element SA1 and the voltage limiting element D1.

SA can bypass high current, however, its firing potential is high and the setting voltage varies widely. In order to compensate these disadvantages, it is combined with D1 of which firing potential is low and the setting voltage does not vary much and suppresses the surge voltage to a low level. D1, which does not tolerate high current, is also protected by R1 which limits the surge current (Figure 3).

The discharge element and the voltage limiting element together are called the surge absorber element. Since there is no one ideal surge absorber element, i.e. small size, small setting voltage variation, fast response time, high discharge withstand current rating, no failure in shortcircuit mode, the surge absorber circuit is designed with combinations of components to bring out their good characteristics.

Which surge protector do you choose?Surge protectors for signal lineM-System’s surge protectors are classified according to sensor/signal types, such as standard 4–20 mA signal, RTD, ther-mocouple, potentiometer, strain gauge and pulse generating device. We also have those specific for various field networks such as RS-485/RS-422, Ethernet, DeviceNet, PROFIBUS, LONWORKS and FOUNDATION Fieldbus.

[Example]

A two-wire transmitter in general transmits 4 to 20mA DC output signal, powered by 24V DC power source on the same loop.

Choose the lightning surge protector for standard signal (ex. MDP-24-1). Both transmitter and control room instrument incorporate electric circuits. Therefore, surge protectors are needed at the both side.

In case of RTD, choose the lightning surge protector for RTD use (ex. MDP-RB). Even though the sensor has no electric circuit, a surge protector should be connected at the detection side in order to prevent the platinum resistance probe from breaking, in addition to the transmitter side.

Surge protectors for power lineMaximum load current up to 200 A is selectable. Single-phase/two-wire, single-phase/three-wire, three-phase/three-wire and DC power supply systems are selectable. Choose one based on the load current and the number of phase.

◆ Applicable to single phase 2/3-wire and three-phase 3/4- wire system.

◆ Degraded head element is automatically sepa-rated from the power lines by the incorporated thermal breaker, and the LED lamp (turns off) and the relay contact alerts the failure status.

◆ Thermal breaker ensures degraded head element to be automatically separated from the power lines to prevent overheating.

◆ Head-base connection is keyed so that only a head element of correct line voltage can be mounted.
