A knowledge of insulation resistance is important, even<br \/>\nwhen the values are comparatively e high, as these values may.be<br \/>\nlimiting factors in the design of high-impedance circuits. Low<br \/>\ninsulation resistance, by permitting the flow of large leakage<br \/>\ncurrents, can.disturb the operation of circuits intended to be<br \/>\nisolated, for example, by forming feedback loops. Excessive leakage<br \/>\ncurrents can eventually lead to deterioration of the insulation by<br \/>\nheating or direct-current electrolysis. Insulation-resistance<br \/>\nmeasurements should not be considered the equivalent of dielectric<br \/>\nwithstanding voltage or electric breakdown tests. A clean, dry<br \/>\ninsulation may have a high insulation resistance, and yet possess a<br \/>\nmechanical fault that would cause failure in the dielectric<br \/>\nwithstanding voltage test. Conversely, a dirty, deteriorated<br \/>\ninsulation with low insulation resistance might not break down<br \/>\nunder a high potential. Since insulating members composed of<br \/>\ndifferent materials or combinations of materials may have<br \/>\ninherently different insulation resistance, the numerical value of<br \/>\nmeasured insulation resistance cannot properly be taken as a direct<br \/>\nmeasure of the degree of cleanliness or absence of deterioration.<br \/>\nThe test is especially helpful in determining the extent to which<br \/>\ninsulating properties are affected be deteriorative influences,<br \/>\nsuch as heat, moisture, dirt, oxidation, or loss of volatile<br \/>\nmaterials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Passive Electronic Component Parts, Test Methods for; Method 13: Insulation Resistance Test<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/ecia\/\"><b>ECIA<\/b><\/a><\/td>\n<td>1978<\/td>\n<td>5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":0,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2649],"product_tag":[],"class_list":{"0":"post-556690","1":"product","2":"type-product","3":"status-publish","5":"product_cat-ecia","7":"first","8":"instock","9":"sold-individually","10":"shipping-taxable","11":"purchasable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/556690","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=556690"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=556690"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=556690"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
