Medium-voltage switchgear and compact substations are both used in power distribution systems, but they perform different functions. The confusion often occurs because medium-voltage switchgear can be installed as a standalone lineup or integrated into the medium-voltage compartment of a compact substation. Medium-voltage switchgear is primarily used to connect, control, isolate, […]

A distribution transformer is one of the most important components in a power distribution system. It converts medium-voltage electricity from the utility grid into a lower voltage that can be safely used by factories, commercial buildings, residential communities, data centers, renewable energy facilities, and other electrical loads. Selecting the right

Choosing the correct transformer capacity is essential to industrial power reliability. An undersized transformer may overheat, suffer voltage drop, trip during motor starting, and age prematurely. An oversized unit may increase purchase cost and no-load losses. Reliable transformer sizing should consider connected load, demand factor, power factor, operating load ratio,

Electrical engineers, contractors, facility managers, and equipment buyers often need to convert transformer capacity from kVA to amps. This calculation is essential when selecting cables, circuit breakers, busbars, switchgear, protection devices, and downstream distribution equipment. A transformer may be rated at 500 kVA, 1000 kVA, or 2500 kVA, but these
