MV Panels: Features, Design, and Installation

Technological advancements have enhanced the safety and dependability of medium voltage systems. Traditionally, fixed solutions were used that included an enclosure containing the devices required by the electrical system. The equipment in such enclosures could not be manually removed or reinserted for maintenance. The connections could only be isolated with the help of a disconnecting switch. The advent of withdrawable MV panels allows the removal of all the individual parts without impacting the rest of the system. In this article, we look at the features, design, and installation of mv panels in detail.

What is an MV Panel?

An MV panel is a cluster of electrical gear that is enclosed in a metallic structure. The panel consists of various transformers, circuit breakers, fuses, and switches. MV panels are leveraged to control, protect, and segregate the electrical equipment. Medium voltage panels can be found across a range of power distribution and transmission systems in large to medium-sized facilities.

Features of MV Panel

  • MV panels enclose electrical gear up to a total of 36kV
  • The standard equipment included in medium voltage panels includes minimum oil circuit breakers or bulk oil circuit breakers
  • The interruption medium leveraged by MV panels can be oil, vacuum, or any other insulating gas like SF6.
  • Depending on the kind of enclosure and installation, MV panels can be categorized into gas insulated, air, or vacuum.

The Uses of MV Panels

  • MV panels or switchgear are primarily used as a switch to complete or break the connected circuits
  • Switchgear is an important component in a variety of power applications. It secures the connected gear from extreme power surges and protects the equipment and operations from any form of disruption
  • MV panels can seamlessly protect the generators and transformers from short circuits.
  • MV panels can also be effectively leveraged to isolate the connected devices from the primary power source. This helps operators to carry out maintenance operations without disrupting the power supply of the entire facility

Design and Installation

MV panels come in a variety of designs and installation options.

  • Gas insulation: A sealed design filled with SF6 or sulfur hexafluoride, these MV panels make the installation process seamless  
  • Metal clad panels: Classified by IEEE C37.20.2, it comprises all the electronic components in an MV panel inside individual metal enclosures. This would consist of the output bus, input bus, the primary circuit breaker/switch, and the measuring instrument.
  • Pad-mounted panels: Classified by the IEEE C37.74 standard, this design is ideal for underground distribution systems with voltage spanning 5 to 38kV. Pad-mounted panels have a lower degree of complexity coupled with exceptional high-temperature resistance.
  • Metal enclosed panels: Defined by IEEE C37.20.3, this design consists of protection devices like fuses, circuit breakers, and other transformers. This design is leveraged in a variety of industrial and commercial establishments.

Opting for the Right Electrical Service Provider

With MV panels making power distribution seamless across the board, the final decision comes down to finding the right electrical service provider. With a myriad of brands in the market, finding the right one can seem arduous. Our recommendation would be to do thorough research as the right call will significantly impact the purchase.

The best service providers will have an exceptional track record of service and provide facility managers with a product that resonates perfectly with the needs of the organization. Searching the web for organic customer testimonials can give facility owners a clear idea of the foremost service providers in their proximity.
