The Complete Guide to Shielding Your Industrial AC Surge Protection

In today’s rapidly shifting world of technology, one problem area that needs constant repair and maintenance is Industrial AC Surge Protection. In this guide, we will review the goals, types of devices, and their applications, along with providing detailed technical descriptions of SPDs for industrial use.

AC T2+T3 Surge Protective Device – Advanced Industrial AC Surge Protection

The AC T2+T3 Surge Protective Device offers double-tier protection with type T2 and T3 surge protective elements. Devices provide surge overvoltage protection. It is designed to mitigate medium energy surges from lightning and low energy spikes during switching operations for an industrial superlative class system.

These Industries and Their Uses

The surge protective devices provide flexible, maintainable construction for PLC-controlled technical processes. Most effective Absorption suitable for most residential buildings, offices, and industrial premises, transcending into widely diverse areas. This surge absorber is therefore ideal for application in industrial control panels, distribution boards, and other critical infrastructure.

Understanding the Impact of Surge Protection in Industrial AC Circuits

Surge in the context of industrial AC refers to the over-voltage transient phenomena that are reversible, and surge in power flows beyond voltage limits. Power increases may be deleterious due to lightning, system power faults, and switching operations. Proper surge protection is achieved when the following objectives are accomplished: 

• Ensures protection of sensitive equipment 
• Reduction of equipment downtime 
• A decrease in the company’s maintenance costs 
• Meets the company’s safety regulations 

Classification of Protection Devices for Industrial AC Surge 1 

1. Type 1 SPDs 

– Application: These may be placed together with arresters placed where power enters the building. 

– Function: They are effective in protecting equipment from direct strikes of lightning. 

– Standards: They comply with IEC 61643-11 

2. Type 2 SPDs 

– Application: Installed after type 1 SPDs in a distribution board. 

– Function: Protect residual lightning energy and switching surges. 

– Standards: Conform to UL1449 and IEC 61643 – 

3. Type 3 SPDs 

– Application: Fixed next to the sensitive appliances. 

– Function: Very low level surge protective capability.

Critical Technical Criteria 

Concerning Industrial AC Surge Protectors, The Following Items Should Be Evaluated: 

• Nominal Discharge current In: indicates how many times the impact of an SPD can be repeated, as well as defining its peak pulse current outputs. 

• Maximum Discharge Current (Imax): The maximum value of surge current achievable on the SPD.

• Voltage Protection Level (Up): It is a form of residual voltage that the SPD will permit passage of a surge. 
• Maximum Continuous Operating Voltage (Uc): It is the upper limit voltage at which the SPD can operate continuously. 
• Response Time: SPD’s time interval to surge. 

Use in Industrial

Numerous electrical interferences are common in the industrial environment. Implementation of Surge protection is vital in: 

– Safeguarding machinery and automation systems in manufacturing plants. 

– Protecting servers and networking devices in data centers. 

– HVAC systems for controlling climate operations. 

– Pumping stations for the uninterrupted delivery of water or chemicals. 

– Control panels for safeguarding control systems. 

Innovative Capabilities of Modern SPDs 

Advanced features enhance the effectiveness of modern industrial SPDs: 

– Remote Signaling. Monitoring the SPD from a centralized position. 

– Thermal disconnection. Safe disconnection in the event of an SPD failure. 

– Pluggable Modules. Module replacement without stopping the system. 

– Simplified mounting in control panels. 

Selecting the Right Surge Protective Device for Industrial AC Surge Protection

Aligning a Surge Protective Device (SPD) with the industrial electric systems framework is pivotal in increasing its operational lifetime and ensuring optimal performance. Consider the following while selecting the AC Surge Industrial Protection: 

System Voltage Compatibility

The SPD’s Maximum Continuous Operating Voltage (Uc) must always be sighted from the system’s voltage level. As an example, in an industrial power system of 480V, an SPD of 480V is adopted. This ensures that the protection device is reliable during regular operations as well as during surge activities. The device will perform as expected. 

Surge Exposure Levels Determination 

Depending on the facility, assess its overall surge profile that characterizes its exposure level over time and space, including transients’ intensity and frequency. Places with outdoor installations and heavy manufacturing power usage have high risk exposure. SPDs designed for such applications should exceed 100kA. 

Device Placement Position Matters

Effectiveness is influenced by placement. Panel mount AC surge protection should be used for MCCs, while for the DIN-rail mounted SPDs, use the standard DIN rail. These positions provide effective surge protection. 

Protecting Sensitive Equipment 

A low-voltage protection Rating (Up) type SPD that restricts excess voltage should be employed to protect delicate electronics and the Variable Frequency Drive (VFD) components.  For industrial electrical surge protection service, Telebahn has been rated the highest for SPDs. 

Conclusion 

Surge protection for industrial AC needs is as vital as preserving equipment and reducing operational disruption. Strategic safety measures must be put into place as well. It is best to understand SPDs in terms of their classification, functions, and other technical details. Such knowledge helps industries make informed decisions in protecting their electric systems.  In case these or any other solutions tailored to your industry interest you, reach out to Telebahn.
