[Distribution grids, mini-grids and interconnectors](https://www.materialinsights.org/energy/e_distribution/) (energy) and [Transformers and power electronics](https://www.materialinsights.org/energy/e_power_electronics/) (energy): 3 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · Direct · Distribution grids, mini-grids and interconnectors → Transformers and power electronics*

Chargers and adaptors convert mains power for devices.

### 2. Energy flow

*Physical flow · 85% of flow · Transformers and power electronics → Distribution grids, mini-grids and interconnectors*

Distribution transformers deliver usable voltage.

- **85%** of Transformers and power electronics's energy goes this way

### 3. Price link: grid equipment

*Cost and price · Strong · Both ways*

Inverters, transformers and smart switching devices are installed together in distribution upgrades. The indices share the grid spending cycle, so yearly moves correlate at 0.70, though monthly changes barely relate, at 0.10, because list prices are revised infrequently.

- **0.10** monthly change correlation
- **0.70** 12-month change correlation
- **0.84** fitted elasticity
