Electrical substation videos

Electrical power is amazing and dangerous at high voltages. Electrical substation is a part of an electrical generation, transmission, and distribution system that transform voltage from high to low, or the reverse, or control the flow of electrical power. Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control. Here is a collection of videos on electrical substations:

    Feuer und Explosion in RWE-Trafostation, in Siegen-Weidenau

    A fire in one of the transformers of the RWE-substation in Weidenau, width road, occurred this afternoon 3.01.2013) caused by an explosion of an insulator that is filled with oil. Initially nothing was noticed at the competent energy verse Oger of it all. There was not even a short surge of power which appear there immediately.
    After first investigations is caused by a “ground stop” (short circuit), in consequence of which it came to an extremely high current flow, which so severely overheated the insulator, that it exploded and was blasted off. Debris broke through a massive protection fence,

    Birds make a power transformer “explode” in Houston (the fuse really)

    If a huge flock of birds sitting on a hydro line leave all at once they make the line swing (known as a swing short) which causes a cut out fuse to blow

    Electrical Substation Tour

    Harris provided construction management services for an electrical substation project in the Silicon Valley. In this video, Harris Project Manager Rocco Colicchia gives a tour of the substation and discusses the services Harris provided. The project reached completion in March and the municipal utility’s crews successfully connected the new substation to the 60kV line.

    Circuit Breaker Testing

    Circuit breakers allow the flow of energy to be controlled by safely switching currents on and off at all voltage levels of the energy grid. The interrupter and the mechanical drive are the main components that are subject to wear and aging. In order to ensure the proper operation of a circuit breaker throughout its lifetime, diagnostic tests are performed, such as resistance, timing, minimum pick-up, travel, and power factor.

    Power Transformer Testing – Measuring capacitance and power factor or dissipation factor

    The condition of the bushings and the overall insulation of power transformers can be investigated by measuring the capacitance and dissipation factor, also known as the tangent delta, or power factor. Aging and decomposition of the insulation, or the ingress of water, increases the losses and thus more energy is turned into heat in the insulation. The level of this dissipation is expressed by the dissipation factor or power factor. The CPC 100 together with the CP TD1 can measure the capacitance and dissipation factor or power factor in laboratories, test fields, and on site.

    Transformator fault

    This 1 MVA transformator was causing low voltage on one of the phases in the street. ( industrial area )
    After a planned shutdown and lowering the oil level it was quickly determined what the fault was.
    Poor contact in the off load tap changer sliding contacts.caused some taps to fail 1 – 2.
    As a temp solution we shifted the tap selector to 3 – 4. Off load voltages were 242 / 422 Volts, as soon load was applied it dropped on the red phase to 205 / 360 Volts. other two phases were alright.
    The tap-changer contact ( not visible ) had failed.

    DC measurements of the 11 kV HV windings were 1.3 , 1.3 and 2.5 Ohms ( faulty )

    Pad-Mounted Transformer Safety Procedures

    Underground electrical systems are becoming wide-spread throughout the world. Performing work around pad-mounted transformers and switchgear requires that lineworkers be qualified in the skills to recognize energized parts. OSHA regulations stipulate training in the technical and safety practices to inspect and work on this type of equipment.
