The watt-hour meter conforms to all technical requirements stipulated in national standard GB\/T17215.311-2008 Alternating Current Watt-hour Meters for Active Energy (Classes 0.5, 1 and 2), and total technical requirements for\u00a0single-phase watt-hour meters (class 2) stipulated in international standard IEC 521.<\/p>\n\n\n\n<p>2. The watt-hour meter can be designed into two kinds: direct connection type and the type of connection through&nbsp;a multi-purpose current transformer or a multi purpose voltage transformer.<\/p>\n\n\n\n<p>3. According to users&#8217; requirements, the special watt-hour meters can be designed, including the watt-hour meter that&nbsp;has a different reference frequency, reference voltage, different current specifications, positive and negative accumulation,&nbsp;and a non-return function &nbsp;<\/p>\n\n\n\n<p>4. Start: under reference voltage, reference frequency, and COS\u03c6=1, when the load current can&#8217;t exceed 0.5% of the basic&nbsp;current, the rotor of the watt-hour meter can start and rotate continuously.<\/p>\n\n\n\n<p>5. Creeping: when the current circuit of the watt-hour meter has no current, and the voltage applied to the voltage circuit is 80%~110%&nbsp;of the reference value, the rotary disc of the watt-hour meter rotates not more than 1 circle.<\/p>\n\n\n\n<p>6. Power consumption: under the reference voltage, reference temperature, and reference frequency, the active energy&nbsp;consumption of the watt-hour meter voltage circuit can&#8217;t exceed 2W.&nbsp;<\/p>\n\n\n\n<p>7. Dielectric performance: when the watt-hour meter can withstand the impact waveform (standard 1.2\/50\u03bcs waveform)&nbsp;and the impact voltage of 6kV peak value for 10 times respectively, it won&#8217;t be damaged. The circuit-to-earth of the watt-hour&nbsp;meter can withstand a sine waveform of 2kV and 45~65Hz at AC voltage for 1 minute.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Produce_Specification\"><\/span><strong>Produce Specification<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"http:\/\/zmgs.com\/en\/upload\/2017-09-21\/f333eaad00d4b7596273b4f141f1f28c.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"External_And_Installation_Size\"><\/span><strong>External And Installation Size<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"547\" height=\"564\" src=\"https:\/\/mediumslateblue-chimpanzee-835813.hostingersite.com\/wp-content\/uploads\/2025\/09\/image-14.png\" alt=\"\" class=\"wp-image-684\"\/><\/figure>","protected":false},"excerpt":{"rendered":"Application DD862 type single-phase watt-hour meter, that is,&nbsp;an inductance type single-phase AC active energy&nbsp;watt-hour meter, is used for measuring active&nbsp;energy at a single-phase AC power grid of 50Hz or&nbsp;60Hz.
