  • SF6 Training and Certification | EA Technology

    Create Safer, Stronger, Smarter Networks. Since the Fluorinated Greenhouse Gas Regulations were revised in 2014, if you carry out any activities that directly involve the recovery or handling of SF 6 from high voltage (HV) switchgear, then you need to have passed a theoretical and practical examination in SF 6 handling and hold a certificate of competence issued by an accredited certification

  • SF6 Gas-Insulated Transformer | Transformer | MEIDENSHA

    SF6 gas known for its non-flammabilit and coordinative ability with environmental conditions. Lt was widely used in underground substations and inddor substations at underground shopping areas, traffic systems, and public structures. SF6 Gas-Insulated transfomers are designed to reduce fire hazards and less risk on the environment. By directly coupling with gas-insulated Switchgear, substation space can be minimized as the result of compact facilities.

  • SF6 Gas Servicing Equipment – ENERVAC INTERNATIONAL ULC

    Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

  • Decomposition Characteristics of SF6 and Partial Discharge

    The decomposition characteristics of SF 6 under four types of negative DC partial discharge (DC-PD) are obtained. The relationship between the decomposition characteristics of SF 6 and the PD types was further studied. Moreover, back propagation (BP) neural network algorithm [29 38] is used to recognize the PD types.

  • NEC Guidelines for Transformer and Transformer Feeder

    Protection at The Primary Side of The TransformerProtection at The Secondary Side of The TransformerCussion For Section 240.21Transformer primary protection— Overcurrent protective devices (OCPDs) are required as primary protection for transformers when the primary voltage is greater than 1,000V [Tables 450.3(A)] and for transformers with primary voltage of 1,000V or less [Table 450.3(B)], with no Exceptions. However, a fire pump has a special requirement for its transformer primary and secondary protection, which is considered a modification to Art. 450. If a transformer serves a fire pump (Art. 695), its primary OCPD shall be sized per the locked-rotor current of the fire pump, and transformer secondary protection shall not be permitted [695.5(B)]. Transformer primary feeder protection— The NEC does not list any specific Exception for transformer primary feeder protection. An OCPD is required for the transformer primary conductor. The only Exception is found in Sec. 240.4(A). If overload protection of the OCPD would create a power loss hazard, such as fire pump application and some processes at refinery...

    The insulation medium of the blue instrument transformers has no impact on the environment, therefore the Global Warming Potential is zero. SF 6 or other fluorinated gases, called F-Gases, are replaced by applying dry synthetic air, so called „clean air“, as an insulation medium for gas-insulated equipment. Clean air consists of 80% nitrogen and 20% oxygen, natural elements in the surrounding atmosphere.
