A reference in medium voltage, protection and energy efficiency.
Metal-clad switchgear: what are the existing types and how to choose
The metal-clad switchgear houses and protects the substation equipment. See the types and functions.
The importance of electrical grounding in the property
Grounding protects people and equipment. See why no property should be without it.
Protection relay: what it is, ANSI functions and types
The protection relay is the brain of electrical protection: it detects the fault and commands the circuit breaker. See the ANSI functions and types.
Voltage transformer (VT) and current transformer (CT): learn everything
CTs and VTs adapt current and voltage for safe measurement and protection. See how they work.
Autotransformer and isolation transformer: what are the differences
The difference between an autotransformer and an isolation transformer lies in galvanic isolation. See the impact on safety.
Metallic and masonry primary substations: which is better
Metallic or masonry? The choice impacts space, safety, and lead time. See the comparison.
What is a medium voltage circuit breaker and how it protects your installation
The medium voltage circuit breaker is the device that safely interrupts load and short-circuit currents. See how it works, the types, and how to specify.
On-grid, off-grid and hybrid solar energy: differences
On-grid, off-grid or hybrid? The difference lies in the grid connection and batteries. See which to choose.
