Frequently asked

Glossary

1

Switchgear

The assembled combination of circuit breakers, disconnectors, earthing switches, fuses, busbars and control wiring that switches and protects electrical circuits. At Electricity Eurasia, switchgear is usually split by voltage class: LV (up to 1 kV), MV (1-36 kV) and HV (above 36 kV).

2

Air-insulated switchgear (AIS)

Switchgear in which air at atmospheric pressure provides the insulation between live parts. AIS panels are the workhorse of MV distribution substations and are usually shown alongside modular metal-clad cubicles built to IEC 62271-200.

3

Gas-insulated switchgear (GIS)

Switchgear where the live parts sit inside a sealed enclosure filled with an insulating gas (typically SF6 or an SF6-free alternative). GIS is chosen where floor space is scarce or where pollution and humidity are high, so it appears frequently in dense urban network projects and industrial plants.

4

Ring main unit (RMU)

A compact MV switchgear block used on ring distribution networks, typically combining two load-break switches and a fused or breaker-protected transformer feeder. RMUs are a core product family for Turkish distribution utilities and for factory-owned substations.

5

Circuit breaker (MCB, MCCB, VCB)

A device that interrupts current automatically under fault conditions. Miniature and moulded-case breakers serve LV final circuits and panels, while vacuum circuit breakers handle MV feeders and transformer protection; look for rated current, breaking capacity (kA) and IEC 60947 / 62271 references on datasheets.

6

Distribution transformer

The transformer that steps MV down to the LV voltage used by buildings, factories and charging sites. Exhibitors quote rated power in kVA, losses (no-load and load), impedance, cooling class (ONAN, KNAN) and whether the unit is oil-immersed or dry-type.

7

Dry-type transformer

A transformer cooled without liquid, commonly cast-resin for indoor installation in buildings, tunnels, hospitals and metro stations where fire load matters. Cast-resin units are frequently shown next to oil-immersed units so buyers can compare footprint, fire class and loss figures.

8

Busbar and busway system

Rigid conductors that carry heavy current between the transformer, main panel and distribution boards. Sandwich busway and rising-main systems replace cable bundles in high-rise and industrial distribution, and are quoted with current rating, short-circuit withstand and IP protection.

9

Reactive power compensation

Capacitor banks, detuned reactors and active filters that correct power factor and reduce reactive power charges. Turkish industrial electricity tariffs penalise poor power factor, so compensation panels, STATCOM and SVG units are a recurring exhibit category at the show.

10

Harmonics and THD

Distortion of the current or voltage waveform caused by non-linear loads such as drives, rectifiers, LED lighting and EV chargers. Suppliers quote total harmonic distortion (THD) limits and offer active or passive filters when a site approaches the limits set by the distribution operator.

11

SCADA and RTU

Supervisory control and data acquisition software plus the remote terminal units that collect field data from substations. In the power sector, SCADA is the layer where protection settings, breaker status, transformer temperature and energy meters are monitored from a control centre.

12

Smart grid and ADMS

The digital layer of a distribution network: sensors, communication networks, outage management and advanced distribution management systems (ADMS) that let operators see and reconfigure the grid in near real time. It is the bridge between conventional substations and distributed energy resources.

13

Battery energy storage system (BESS)

Containerised or cabinet-based lithium-ion (or alternative chemistry) storage with its power conversion system, thermal management and controls. BESS units are marketed for peak shaving, grid services, backup and co-location with solar plants, and are quoted in MW/MWh plus round-trip efficiency and cycle life.

14

EV charging (AC and DC)

AC wallboxes and DC fast chargers that supply electric vehicles. Buyers compare connector standards (Type 2, CCS2, CHAdeMO), power levels (7-22 kW AC, 50-350 kW DC), OCPP backend compatibility, payment terminals and load management capability.

15

OCPP and load management

Open Charge Point Protocol is the de facto interface between chargers and a charging management system. Load management uses that link to cap site demand, share available power between connectors and avoid costly transformer upgrades at depots and shopping centres.

16

Microgrid

A localised network that can operate connected to or islanded from the main grid, usually combining generation, storage, protection and a controller. Industrial estates and campuses in Turkey use microgrid designs to keep critical loads running through outages.

17

kVA and MVA

Apparent power ratings used for transformers, generators and switchgear. Because apparent power accounts for the phase difference between voltage and current, equipment ratings are quoted in kVA (small units) or MVA (large power transformers) rather than kW.

18

IEC 61439 and IEC 62271

The standard families behind assembled LV switchgear and controlgear (IEC 61439) and high-voltage switchgear (IEC 62271). A panel's nameplate typically declares its standard, rated voltage, rated current, short-circuit withstand and internal arc classification, and buyers use these to compare tenders.

19

Cable management and cable tray

Trays, ladders, trunking, glands and supports that route power and control cables safely. At a power-sector fair this category is judged on load capacity, corrosion class, fire resistance and speed of installation rather than on appearance alone.

20

Smart metering and AMI

Advanced metering infrastructure: meters with two-way communication that report consumption intervals and support remote tariff changes, disconnection and outage detection. It underpins prepaid billing, loss reduction and demand-response programmes.
