class=\"wp-block-paragraph\">While lightning captures the headlines, switching transients are the silent, constant harbingers of hardware degradation. Within an electrical grid, the abrupt interruption of current in inductive loads\u2014such as large utility transformers, neighboring motor drives, or even the grid-tied inverter itself during sudden shutdown sequences\u2014causes voltage &#8220;ringing.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These transients, characterized by high frequency and sub-microsecond rise times, travel through the AC supply lines. When they hit the inverter\u2019s power conversion stage, they subject the Power MOSFETs and Insulated Gate Bipolar Transistors (IGBTs) to cumulative thermal and dielectric stress. Over time, these transients &#8220;wear down&#8221; the semiconductor lattice, leading to a phenomenon known as &#8220;infant mortality&#8221; in components that should have functioned for decades. The SPD\u2019s role, therefore, is not just to survive a strike, but to act as a high-speed diversion path that clips these oscillations before they reach the delicate semiconductor junctions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\uc774\ub7ec\ud55c \uc804\uae30\uc5ed\ud559\uc801 \uc704\ud611\uc744 \uc774\ud574\ud558\ub294 \uac83\uc774 \uc2e0\ub8b0\ud560 \uc218 \uc788\ub294 \uc2dc\uc2a4\ud15c\uc744 \uc124\uacc4\ud558\ub294 \uccab \ubc88\uc9f8 \ub2e8\uacc4\uc785\ub2c8\ub2e4. <strong>\ud0dc\uc591\uad11 \uc11c\uc9c0 \ubcf4\ud638<\/strong> \uacfc\ub3c4 \ud604\uc0c1\uc774 \ud0dc\uc591\uad11 \uc5b4\ub808\uc774\ub97c \ud1b5\ud574 \uc5b4\ub5bb\uac8c \uc804\ud30c\ub418\ub294\uc9c0 \uc608\uce21\ud568\uc73c\ub85c\uc368, \uc5d4\uc9c0\ub2c8\uc5b4\ub294 \ud558\ub4dc\uc6e8\uc5b4\uc758 \uc870\uae30 \uace0\uc7a5\uc744 \uc644\ud654\ud558\uae30 \uc704\ud55c \uc7a5\uce58\ub97c \ub354 \uc798 \uc120\ud0dd\ud558\uace0 \ubc30\uce58\ud560 \uc218 \uc788\uc2b5\ub2c8\ub2e4. <strong>\ud0dc\uc591\uad11 \uc11c\uc9c0 \ubcf4\ud638<\/strong> .<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. \uaddc\ubc94\uc801 \ud504\ub808\uc784\uc6cc\ud06c: IEC 61643-31\uc758 \uc544\ud0a4\ud14d\ucc98<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\uc11c\uc9c0 \ubcf4\ud638 \uc5d4\uc9c0\ub2c8\uc5b4\ub9c1\uc5d0\uc11c \uaddc\uc815 \uc900\uc218\ub294 \ub2e8\uc21c\ud788 \uc778\uc99d \ub77c\ubca8\uc744 \ubd80\ucc29\ud558\ub294 \ubb38\uc81c\uac00 \uc544\ub2c8\ub77c, \uc7a5\uce58\uac00 PV \uc2a4\ud2b8\ub9c1\uc758 \ud2b9\uc815 \uc5d0\ub108\uc9c0 \ud658\uacbd\uacfc \uc77c\uce58\ud558\ub3c4\ub85d \ubcf4\uc7a5\ud558\ub294 \uac83\uc785\ub2c8\ub2e4. \ud0dc\uc591\uad11 \uc11c\uc9c0 \ubcf4\ud638\ub97c \uc704\ud55c \uc8fc\uc694 \uad00\ub9ac \ud45c\uc900\uc740 <strong><a href=\"https:\/\/webstore.iec.ch\/en\/publication\/26931\" target=\"_blank\" rel=\"noopener\">IEC 61643-31<\/a><\/strong>, \uc774\uba70, \uc774\ub294 PV \uc124\ube44\uc758 DC \uce21\uc5d0 \uc5f0\uacb0\ub418\ub294 SPD\uc5d0 \ub300\ud55c \ud14c\uc2a4\ud2b8 \uc694\uad6c \uc0ac\ud56d \ubc0f \uc131\ub2a5 \uae30\uc900\uc744 \uc815\uc758\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3.1 \ud30c\ud615\uc758 \uc911\uc694\uc131: \uc5d0\ub108\uc9c0 \ud504\ub85c\ud30c\uc77c<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Type 1\uacfc Type 2 SPD\uc758 \uadfc\ubcf8\uc801\uc778 \ucc28\uc774\uc810\uc740 \uc7a5\uce58\uc758 \ud2b9\uc815 \uc5d0\ub108\uc9c0 \uc18c\uc0b0 \uc694\uad6c \uc0ac\ud56d\uc744 \uc2dc\ubbac\ub808\uc774\uc158\ud558\ub294 \ud14c\uc2a4\ud2b8 \ud30c\ud615\uc5d0 \uc788\uc2b5\ub2c8\ub2e4.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Type 1 (\uc5d0\ub108\uc9c0 \ubd84\ubc30\uae30):<\/strong> \ub2e4\uc74c \ud30c\ud615\uc73c\ub85c \ud14c\uc2a4\ud2b8\ub428 <strong>10\/350 \u03bcs<\/strong> impulse current wave.

This is typically achieved through robust internal spark-gap technology or massive, reinforced varistor arrays.<\/li>\n\n\n\n<li><strong>Type 2 (\uc804\uc555 \ud074\ub7a8\ud37c):<\/strong> \ub2e4\uc74c \ud30c\ud615\uc73c\ub85c \ud14c\uc2a4\ud2b8\ub428 <strong>8\/20 \u03bcs<\/strong> impulse current wave.

While the peak current may be high, the total energy ($Q$) is significantly lower than that of the $10\/350 \\mu s$ waveform. Type 2 SPDs are designed for precision; their primary objective is to &#8220;clamp&#8221; the residual voltage ($U_p$) to a level that is compatible with the insulation coordination of the inverter\u2019s internal DC bus.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3.2 U_p(\uc804\uc555 \ubcf4\ud638 \ub808\ubca8)\uc758 \uc911\uc694\uc131<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">\uc5d4\uc9c0\ub2c8\uc5b4\uac00 SPD\ub97c \uc120\ud0dd\ud560 \ub54c \uace0\ub824\ud574\uc57c \ud560 \uc8fc\uc694 \uc81c\uc57d \uc0ac\ud56d\uc740 <strong>U_p<\/strong>. \uc785\ub2c8\ub2e4. \uc774 \ub9e4\uac1c\ubcc0\uc218\ub294 SPD\uac00 \uacf5\uce6d \ubc29\uc804 \uc804\ub958\ub97c \ud1b5\uc804\ud560 \ub54c \ub2e8\uc790\uc5d0 \ub098\ud0c0\ub098\ub294 \ucd5c\ub300 \uc804\uc555\uc744 \ub098\ud0c0\ub0c5\ub2c8\ub2e4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an inverter with a maximum withstand voltage (dielectric strength) of, for example, 1500V, the $U_p$ of the SPD must be significantly lower\u2014ideally under 1200V or 1300V\u2014to provide a sufficient &#8220;safety margin.&#8221; The challenge is that $U_p$ is not a static number; it is dependent on the impulse current magnitude. A high-quality Type 2 SPD, such as those used in Kuangya\u2019s industrial line, is engineered to maintain a low $U_p$ even under high-energy pulses, protecting the sensitive gate drivers and microprocessors within the solar inverter.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3.3 Thermal Stability and The &#8220;Fail-Safe&#8221; Necessity<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-1024x576.jpg\" alt=\"\uc5f4 \ucc28\ub2e8 \uba54\ucee4\ub2c8\uc998\uc774 \ud3ec\ud568\ub41c \ud558\uc774\ube0c\ub9ac\ub4dc MOV \ubc0f GDT \uc11c\uc9c0 \ubcf4\ud638 \uc7a5\uce58\uc758 \uc0c1\uc138 \ub0b4\ubd80 \uae30\uc220 \ub3c4\uba74.\" class=\"wp-image-3674\" srcset=\"https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-1024x576.jpg 1024w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-300x169.jpg 300w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-768x432.jpg 768w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-1536x864.jpg 1536w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-2048x1152.jpg 2048w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-18x10.jpg 18w, https:\/\/cnkuangya.com\/wp-content\/uploads\/2026\/06\/spd-hybrid-topology-mov-gdt-kuangya-600x338.jpg 600w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A common point of failure for sub-standard SPDs is the lack of a proper thermal disconnect mechanism.

The role of the Type 1 device is to divert the massive energy of a direct lightning strike (or its massive partial discharge) into the earth-potential equalization system.

When the internal health of the SPD drops below a critical threshold or the thermal fuse triggers, the device sends a discrete signal to the central control room. This allows operations managers to dispatch a maintenance team with the specific replacement module before a system-wide failure occurs.

\uc9c8\ubb38(FAQ)<\/h1>\n\n\n\n<h2 class=\"wp-block-heading\">1. What is the difference between Type 1 and Type 2 SPD in solar systems?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Type 1 SPD is designed to handle <strong>direct lightning strikes (10\/350 \u03bcs waveform)<\/strong> and is installed at the service entrance.<br>Type 2 SPD is designed for <strong>induced surges and switching transients (8\/20 \u03bcs waveform)<\/strong> and is installed in distribution boards.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In solar PV systems, Type 1 is used when there is an external lightning protection system, while Type 2 is the standard protection inside most PV combiner boxes and inverters.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. Can Type 2 SPD replace Type 1 SPD?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No. Type 2 SPD cannot fully replace Type 1 SPD.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Type 2 SPD protects against <strong>indirect surges<\/strong>, but it is not designed to withstand <strong>direct lightning energy levels<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the installation is in a high lightning-risk area or has external lightning protection (LPS), a Type 1 or Type 1+2 combined SPD is required.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. Where should SPDs be installed in a solar PV system?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SPDs should be installed in a <strong>cascaded protection layout<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Type 1 SPD \u2192 Main service entrance (grid connection point)<\/li>\n\n\n\n<li>Type 2 SPD \u2192 PV combiner box \/ distribution board<\/li>\n\n\n\n<li>Type 3 SPD \u2192 Near sensitive equipment (inverter \/ controller)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This ensures multi-layer surge protection from grid to device level.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">4. What happens if SPD is installed too far from the protected equipment?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If the cable between SPD and equipment is too long, the protection performance decreases significantly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even a few meters of cable can create <strong>inductive voltage spikes<\/strong>, which may bypass the SPD protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udc49 Best practice: keep lead length under <strong>0.5 meters<\/strong> whenever possible.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">5. How do I choose the right SPD for a solar installation?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The selection depends on three key factors:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lightning risk level of the site<\/li>\n\n\n\n<li>Whether an external lightning protection system (LPS) exists<\/li>\n\n\n\n<li>System voltage (DC\/AC and inverter specification)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">General guideline:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Residential PV \u2192 Type 2 SPD<\/li>\n\n\n\n<li>Commercial PV \u2192 Type 1+2 SPD<\/li>\n\n\n\n<li>High-risk \/ utility PV \u2192 Type 1 + Type 2 coordinated protection<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">6. Do SPDs need maintenance or replacement?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes. SPDs are consumable protection devices.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They degrade after repeated surge events and should be checked regularly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most SPDs include a visual indicator:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Green \u2192 normal operation<\/li>\n\n\n\n<li>Red \u2192 replacement required<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In high lightning areas, periodic inspection is strongly recommended.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Are you ready to optimize your project&#8217;s surge protection?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ub2f9\uc0ac\uc758 \uae30\uc220 \ud300\uc740 <a href=\"https:\/\/cnkuangya.com\/ko\/\">\ucfe0\uc559\uc57c<\/a> \uc0c1\uc5c5\uc6a9 \ubc0f \uc720\ud2f8\ub9ac\ud2f0 \uaddc\ubaa8\uc758 \uc124\uce58\ub97c \uc704\ud55c \uc0c1\uc138\ud55c \uad6c\uc131 \uc9c0\uc6d0\uc744 \uc81c\uacf5\ud569\ub2c8\ub2e4. \uc628\ub3c4 \ubcf4\uc0c1 \ucd5c\ub300 \uc5f0\uc18d \uc791\ub3d9 \uc804\uc555(MCOV) \uacc4\uc0b0\ubd80\ud130 \uce90\uc2a4\ucf00\uc774\ub4dc \ubcf4\ud638\ub97c \uc704\ud55c \ub9de\ucda4\ud615 CAD \ub808\uc774\uc544\uc6c3 \uc81c\uacf5\uc5d0 \uc774\ub974\uae30\uae4c\uc9c0, \uadc0\ud558\uc758 \ud0dc\uc591\uad11 \uc778\ud504\ub77c\uac00 \uacac\uace0\ud558\uac8c \uad6c\ucd95\ub420 \uc218 \uc788\ub3c4\ub85d \uc9c0\uc6d0\ud569\ub2c8\ub2e4.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>\uc9c0\uae08 \ub2f9\uc0ac \uc5d4\uc9c0\ub2c8\uc5b4\ub9c1 \uc9c0\uc6d0 \ud300\uc5d0 \uc5f0\ub77d\ud558\uc5ec \ud504\ub85c\uc81d\ud2b8 \ud68c\ub85c\ub3c4\ub97c \uac80\ud1a0\ud558\uace0 \uc7ac\uc0dd \uc5d0\ub108\uc9c0 \ud22c\uc790\ub97c \ubcf4\ud638\ud558\uc2ed\uc2dc\uc624.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>1.
