What is a switchgear?

Switchgear is a group of electrical power equipment that serves as a set of distribution, protection, measurement, and control. It also includes other equipment, all placed in a special enclosure. In addition to these devices, inside the housing there are, for example, busbars, electrical connections, insulating elements, and covers. The main task of such a structure is the distribution of electricity, as well as the connection and protection of electrical circuit lines. One type of switchgear is low-voltage switchgear.

For which purpose are low-voltage switchgears used?

LV switchgear, or low-voltage switchgear, is designed for the transmission and distribution of electricity, as well as power supply and protection of electrical equipment from the effects of short circuits and overloads. They find their application in municipal and building electrical substations, as well as in industrial plants, department stores, and other public facilities.

Depending on the location of its installation, low-voltage switchgear is divided into an indoor and an outdoor switchgear. All low-voltage switchgear can be equipped with the following:

Switching apparatus: disconnectors, fuse disconnectors, circuit breakers with manual or motorized drives,
Measuring apparatus: current and voltage transformers, electricity meters, analyzers of network parameters,
Reactive power compensation systems,
Control systems, e.g. lighting,
Systems of automatic reserve switching (SZR).

Technical parameters of switchgears

Low-voltage switchgears, depending on the purpose and functions performed, may differ from one another, mainly in terms of parameters, technical aspects, and the resulting design.

Basic parameters of LV switchgears:

U_n [V] – rated voltage,
I_n [A] – rated current,
I_cw [kA] – rated short-circuit withstand current,
IP / IK degree of protection:
- IP – protection against solid bodies and water ingress,
- IK – protection against mechanical impacts.

The cabinet enclosure is made of bent aluminium sheet, which is previously degreased, phosphated and powder-painted in any colour or of plastic (fibreglass reinforced thermosetting polyester). Cabinets made of aluminium sheet have a double roof to prevent condensation of water vapour. The structure is mounted on a concrete foundation (views and dimensions of prefabricated concrete foundations were presented in the “Cable connection boxes in aluminium enclosures” chapter in section 5.2). A lightweight enclosure of aluminium sheet facilitates transportation and placement. Manufacturing technology and advantages of plastic cabinets are described in the “Cabling, metering and cabling & metering connection boxes constructed with plastic enclosures” chapter.

Cable, metering boxes in thermosetting cubicles

Cable boxes manufactured by ZPUE S.A. are based on the company's SKR fibreglass reinforced plastic enclosures and metal enclosures. They form the basic elements of cable-based LV power grids. Depending on intended requirements, they are used for the electricity distribution, electricity metering and to protect against the effects of overloads and short-circuits in low voltage cable grids. They allow feeding out from a low voltage cable route and supplying of consumers with an internal power line. They function as final or intermediate connections.

The offer of ZPUE S.A. includes a varied range of connection boxes: cabling, metering, cabling & metering, which were constructed in close cooperation with power distribution companies. Cabling, metering and cabling & metering connection boxes constructed with thermosetting plastic enclosures and metal enclosures may be installed outdoors in a free-standing version with foundations, as wallmounted or as part of a building facade.

The transmission of reactive power in a power grid system reduces the quality of power grid parameters and increases payments for electricity. The ZPUE S.A. company provides solutions for inductive and capacitive reactive power compensation, such as:

capacitor banks,
capacitor banks with protective reactors,,
inductive banks (to be agreed with the manufacturer, after analysis of electrical grid parameters at the facility).

Reactive power compensation in an electric power system

There are three levels of reactive power compensation:

Central compensation
The bank is installed at the main switchgear (most frequent use).
Group compensation
The bank is installed at the sub-switchgear or near a group of consumers (wide cable grid, distributed consumers).
Individual compensation
Capacitors installed at individual consumers (high power consumers).

Reactive power compensation in an electric power system

²⁾ The banks may constructed in 500 V and 690 V versions.
³⁾ In case of 690 V banks the insulation voltage is 750 V.
⁴⁾ May be constructed up to IP54.

General principles for capacitor bay selection

The share of reactive power in total power consumption is determined by two coefficients. The first is the power coefficient cosφ, which is presented in the relationship (1.1)

The closer to one cosφ is, the smaller is the share of reactive power. Energy suppliers usually use power factor tgφ in their settlement contracts. A power factor tgφ was received from the relationship (1.2)

The closer to 0 tgφ is, the smaller is the transmission of reactive power. Based on the obtained tgφ and the demand for active power an approximate capacitor bank power may be obtained. The QBat bank power is established from the relationship (1.3)

Where tgφ — power factor required by the energy company.

Note!
For the correct selection of a capacitor bank it is necessary to perform electrical grid measurements at the facility.

Protecting the capacitor bank against adverse impact of harmonics.

The use of rectifiers, inverters and frequency converters in state of the art electricity consuming devices often causes deformation of voltage and current, which changes their waveform so that it is no longer a sine wave. They include numerous harmonics, which are an undesirable phenomenon, shortening the lifetime of electrical devices. This phenomenon is particularly dangerous in a capacitor bank. Capacitor reactance decreases when frequency increases, which results in a high intensity current flowing through the capacitor and destroying it. In order to protect the capacitor bank against adverse impact of harmonics, protective reactors connected in series with capacitors are used.

The degree to which distortions are present in the grid (the amount of harmonics) is specified by THD (Total Harmonic Distortion). The type of capacitor bank protection is selected depending on THD value.

THD ≤ 15%	Capacitor bank with normal capacitors (U_{n Kond} = 400 V)
15% ≤ THD ≤ 25%	Capacitor bank with heavy duty capacitors (U_{n Kond} = 440 V)
25% ≤ THD ≤ 50%	Capacitor banks with compensating reactors
THD > 50%	Semiconductor-based tracking compensator
