Surge Protection Devices

What is a Surge Protective Device (SPD)?

The Surge Protective Device (SPD) is a component of the electrical installation protection system. This device connects in parallel to the power supply circuit of the loads that it has to protect. The surge protective device redirects electrical currents like nominal discharge current from a short circuit. It does that using either a solid-state contact or an air-gap switch. In addition, the surge protective device serves as a load-safe shutoff device for overcurrent conditions and a recloser that controls the voltage level above the rated voltage or low voltage in the event of a fault condition. We can also use the surge protective device at all levels of the power supply network. This approach is often the foremost commonly used and most effective sort of overvoltage protection.

Surge protective device connected in parallel features a high impedance. In other words, the sum of the series impedance is equal to the impedance of one surge protective device. Once the transient overvoltage appears within the system, the device’s impedance decreases, so surge current is driven through the surge protective device, bypassing the sensitive equipment. That is to protect equipment against overvoltage transients and disturbances, such as voltage spikes and electrical surges, frequency variations and over-voltages caused by switching operations or lightning. When a user installs a surge strip or a surge protective device into a power line coming from a power utility that includes smoothing capacitors, surge suppressors are not necessary because these capacitors already protect from sudden changes in voltage level.

Surge Protective Device (SPD) Function

In general, The function of a surge protective device (SPD) is to protect the lightning power supply system of the mains electricity network against the direct current (DC) voltage surge or abnormally high voltage. The surge protective devices (SPD) set consists of a surge protective device (SPD), disconnecting switches, circuit breaker and overload relay box.

Moreover, these surge protective devices are a cost-effective solution to forestall downtime, improve the system and data reliability, and eliminate apparatus damage because of transients and surges for power and signal lines. The surge protective device is suitable for any facility or load (1000 volts and below). In addition, surge arresters have many functions, and we might use them anywhere from protecting a home to a utility substation. The electrician installs this device on circuit breakers inside a residential home, pad-mounted transformers, pole-mounted transformers, pole-mounted riser poles, and substations.

Typical Surge Protective Device applications within industrial, commercial, and residential include:

  1. Power distribution. 
  2. Control cabinets. 
  3. Programmable logic controllers. 
  4. Electronic motor controllers. 
  5. Equipment monitoring. 
  6. Lighting circuits. 
  7. Metering. 
  8. Medical equipment. 
  9. Critical loads. 
  10. Back-up power.
  11. UPS. 
  12. HVAC equipment. 
  13. Communication circuits. 
  14. Telephone or facsimile lines. 
  15. Cable TV feeds.
  16. Security systems.
  17. Alarm signalling circuits. 
  18. Entertainment centre or stereo equipment. 
  19. Kitchen or household appliances.

Surge Protective Device (SPD) Working Principle

In the most elementary sense, when a transient voltage occurs on the protected circuit, a surge protective device interrupts the current path by closing its switch contacts, limits the transient voltage and diverts the current back to its source or ground. That prevents damage to connected equipment due to voltage transients. The surge protective device must have at least one non-linear component. That transitions between a high and low impedance state under different conditions to function.

At standard operating voltages, the surge protective device is during a high-impedance state and does not affect the system. When a transient voltage occurs on the circuit, the surge protective device moves into a state of conduction (or low impedance) and diverts the surge current like the nominal discharge current back to its source or ground. This limits or clamps the voltage to a safer level. The surge protective device automatically resets to its high-impedance state after the transient diverts.

Surge Arrester vs Surge Protector

The surge arrester is one of the essential parts of an electrical system. It helps protect expensive circuit components by diverting overvoltage surges to earth or another safe location, preventing them from reaching equipment connected to the system. On the other hand, the surge protector is an electrical device for protection against power surges. Power surges are transient increases in the voltage supplied by a power source or sudden voltage changes. Non-faulty equipment (often incorrectly installed) and faulty equipment can cause surges. A surge protector also protects the system from such surges and enhances the electronic for longer life.

A surge arrester (or lightning arrester) serves the same purpose as a surge protector: they protect electrical equipment from over-voltage conditions. Moreover, they are both commonly referred to as SPDs (Surge Protection Devices). However, the differences between the two are the scale of the protection. Large-scale protection (medium to high voltage) relates to the surge arrester, while surge protector is small-scale (low voltage). A Surge protector can be appliance-specific, such as a surge protector for washing machines, refrigerators, or whole house surge protector.

Utility companies use surge arresters (or lightning arresters) in power transmission and distribution systems to protect their electronic equipment and infrastructure. Large-scale industrial operations, such as mining or oil and gas, also use such devices. These protect against vast fault currents, such as those caused by lightning – hence the name “lightning arrester”. The surge protector is used to protect domestic and consumer electrical equipment. The device surge protector covers sensitive electronic equipment and appliances in your homes like your computer, television, and refrigerator.

SPD Installation

  • Firstly, locate the surge protective device as close as possible to the panel to be protected. 
  • Secondly, drill and punch a hole within the surge protective device housing in an exceedingly position to attenuate the length of the connecting wires from the lugs of the surge protective device to the circuit breaker within the adjacent panel (or fused disconnect lugs).
  • Further, where possible, use a close-nippled connection with wires going on to the first breaker at the top of a panel. Using a close-nippled link with wires going on to the first breaker at the top of a panel ensures optimum protection of all loads connected to the panel. 
  • Use AWG #10 stranded wire or larger (widely available and straightforward installation) to connect the surge protective device and the breaker panel. Avoid sharp bends and excess length within the wiring. Neat installations are not necessarily the foremost effective ones. Short, direct connections are best. 
  • Finally, connect the surge protective device through an appropriately rated circuit breaker, not into the main lugs of the panel. The electrician should use a fused disconnect switch to connect the lines and facilitate surge protective device servicing where circuit breakers are unavailable or impractical.

Surge Protective Device (SPD) vs Lightning Protect System

On a basic level, the lightning protection system protects the facility and structure from direct strikes, while a surge protective device preserves electrical equipment and systems against surges or transients. How the two work, as well as the components involved, differ. In other words, lightning protection system components are always in place and prepared to function. At the same time, a surge protective device monitors internal system voltages and springs into action if a transient voltage occurs on the circuit. 

Surge Protective Device Type 1 and Type 2

GEYA produces and distributes surge protective devices Type 1 and Type 2, and their definitions are as follows:

Surge Protection Devices Type 1:

This type is Permanently connected, intended for installation between the secondary of the service transformer and therefore the line side of the service disconnect the overcurrent device (service equipment). The primary purpose of type 1 is to protect insulation levels of the electrical system against external surges caused by lightning or utility capacitor bank switching.

Surge Protection Devices Type 2:

On the other hand, surge protective device type 2 is permanently connected, intended for installation on the load side of the service disconnect overcurrent device (service equipment), including brand panel locations. Type 2 primary purpose is to protect the sensitive electronics and microprocessor-based loads against residual lightning energy, motor generated surges, and other internally generated surge events. 

SPD for Home

In contrast, a home surge protector is a device installed to protect all the appliances in your home from any electrical spikes by limiting excess electrical current by blocking its flow or shorting these electrical surges to the ground. The surge protector typically uses a feature called metal oxide varistors (MOVs) to protect you against the surge. So, if a power surge occurs, the surge protector will keep any harmful electrical currents from damaging your home devices. Surge protective devices are usually attached to the electrical service box in residence.

Electrical systems such as air conditioners, pool pumps, generators, solar, cable, network, and communication connections can all let power surges into your home. Hence the need to safeguard both the interior and exterior of these devices. We encourage adding protective devices on appliances (which we will also help with) and installing devices on the main electrical panel. 

In conclusion, GEYA has adopted the market-leading surge suppression solution. That is because it provides complete surge protection against lightning, equipment surges, supply disruptions or electrical spikes. The company ensures highly reliable, safe and efficient performance in harsh conditions. That is where split-second response to fault conditions can safeguard valuable assets.
