Surge Protection Devices

What is a Surge Protection Device (SPD)

The Surge Protection 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. We can also use it at all levels of the power supply network. This approach is often the foremost commonly used and most effective sort of overvoltage protection.

SPD connected in parallel features a high impedance. Once the transient overvoltage appears within the system, the device’s impedance decreases, so surge current is driven through the SPD, bypassing the sensitive equipment.

 

 

Surge Protection Device (SPD) Function

Surge protection is 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. It is suitable for any facility or load (1000 volts and below). 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 SPD applications within industrial, commercial, and residential include:

Power distribution, control cabinets, programmable logic controllers, electronic motor controllers, equipment monitoring, lighting circuits, metering, medical equipment, critical loads, back-up power, UPS, HVAC equipment,Communication circuits, telephone or facsimile lines, cable TV feeds, security systems, alarm signalling circuits, entertainment centre or stereo equipment, kitchen or household appliances.

 

Surge Protection Device (SPD) Working Principle

In the most elementary sense, when a transient voltage occurs on the protected circuit, an SPD limits the transient voltage and diverts the current back to its source or ground.

The SPD 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 SPDs are during a high-impedance state and do not affect the system. When a transient voltage occurs on the circuit, the SPD moves into a state of conduction (or low impedance) and diverts the surge current back to its source or ground. This limits or clamps the voltage to a safer level. The SPD automatically resets to its high-impedance state after the transient diverts.

 

Surge Arrester vs Surge Protector

A surge arrester (or lightning arrester) serves the same purpose as a surge protector: they protect electrical equipment from over-voltage conditions. They are both commonly referred to as SPDs (Surge Protection Devices).

The difference between the two is the scale of the protection. Surge arresters are for large-scale protection (medium to high voltage), while surge protectors are small-scale (low voltage). Surge protectors 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.

These protect against vast fault currents, such as those caused by lightning – hence the name “lightning arrester”.

Surge protectors are used to protecting domestic and consumer electrical equipment. They cover electronic appliances in your homes like your computer, television, and refrigerator.

 

Surge Protection Device (SPD) Installation

  • Locate the SPD as close as possible to the panel to be protected.
  • Drill and punch a hole within the SPD housing in an exceedingly position to attenuate the length of the connecting wires from the lugs of the SPD to the circuit breaker within the adjacent panel (or fused disconnect lugs).
  • 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 connection 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 SPD 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.
  • SPDs should be connected through an appropriately rated circuit breaker, not into the main lugs of the panel. The electrician should use a fused disconnect switch to connect with the lines and facilitate SPD servicing where circuit breakers are unavailable or impractical.

 

Surge Protection Device (SPD) vs Lightning Protect System

On a basic level, the lightning protection system protects the facility and structure from direct strikes, while SPDs preserve electrical equipment and systems against surges or transients.

How the two work, as well as the components involved, differ. Lightning protection system components are always in place and prepared to function, while SPDs monitor internal system voltages and spring into action if a transient voltage occurs on the circuit.

 

Surge Protection Device Type 1 and Type 2

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

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

Type 2: Permanently connected, intended for installation on the load side of the service disconnect overcurrent device (service equipment), including brand panel locations. Their 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.

 

Surge Protection Device for Home

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 it to the ground. They typically use a feature called metal oxide varistors (MOVs) to protect you against the surge. So, if a power surge occurs, the device will keep any harmful electrical currents from damaging your home devices. Surge protectors are usually attached to the electrical service box in the residence.

Electrical systems such as air conditioner, 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.

 

Surge Protection Device (SPD) vs Lightning Protection System

On a basic level, the lightning protection system protects the facility and structure from direct strikes, while SPDs preserve electrical equipment and systems against surges or transients.

How the two operates and the components involved also vary. Lightning protection system components are always in place and prepared to function, while SPDs monitor internal system voltages and spring into action if a transient voltage occurs on the circuit.
