Electricity powers every industry, but have you ever thought about how high-voltage power is measured safely?
Direct measurement is risky and inaccurate. Therefore, a metering cubical comes in. It is a smart and secure system that helps measure electricity usage without handling dangerous voltage directly.
Inside one strong enclosure, it combines key components like CTs, PTs, and energy meters to give accurate readings. This not only improves safety but also ensures correct billing and better energy control. From factories to commercial buildings, a metering cubical plays a key role in measuring electricity efficiently and avoiding costly errors.
What is a Metering Cubical?
A metering cubical (or cubicle) is a metal enclosure that contains electrical measuring instruments used to calculate energy consumption.
A metering cubical is a protective box that houses CTs, PTs, and energy meters to measure electricity usage accurately and safely.
Why Metering Cubical is Important?
In industries and large buildings, electricity consumption is high. Measuring it directly is not safe due to high voltage and current. That’s where a metering cubical becomes essential.
Key reasons why it is important:
- Ensures accurate electricity billing
- Helps monitor energy consumption
- Improves electrical safety
- Prevents power theft and tampering
- Supports energy management and cost control
Without a metering cubical, measuring high-voltage electricity would be unsafe and inaccurate.
Where is the Metering Cubical Installed?
Metering cubicals are installed at a specific point in the electrical system.
Common installation locations:
- Between the incoming power supply and the transformer
- At industrial plants and factories
- In commercial buildings and malls
- At electrical substations
- In renewable energy systems (solar/wind)
Position in System:
Power Supply → Metering Cubical → Transformer → Load
This placement ensures that all electricity consumption is measured accurately before it is used.

How Metering Cubical Works?
Understanding how a metering cubical works is simple when explained step by step. It safely measures high-voltage electricity by converting it into values that can be recorded accurately.
Step 1: Power Entry
High-voltage electricity from the supply line enters the metering cubical. This power is too strong to be measured directly, so it needs to be reduced to safe levels.
Step 2: Current Measurement (CT)
The Current Transformer (CT) reduces the high current flowing in the system to a lower, measurable value. This allows safe and accurate current measurement without direct exposure to high current.
Step 3: Voltage Measurement (PT)
The Potential Transformer (PT) reduces the high voltage to a safer level. This ensures that the voltage can be measured without damaging the meter or creating safety risks.
Step 4: Energy Calculation
The energy meter receives the reduced current and voltage values from the CT and PT. Using these inputs, it calculates the total electrical energy consumed over time.
Step 5: Data Output
The meter records and displays the electricity usage. This data is used for billing, monitoring consumption, and managing energy efficiently.
Types of Metering Cubicals
Metering cubicals are classified based on voltage and installation.

Applications of Metering Cubical
Metering cubicals are used in many sectors.
Common applications:
- Industrial manufacturing units
- Factories
- Shopping malls
- Commercial buildings
- Hospitals
- Power distribution companies
- Solar and wind power plants
They are essential wherever large-scale electricity usage needs to be measured.
Why Modern Industries Prefer Metering Cubicals
In older systems, CTs, PTs, and meters were installed separately. This caused:
- More wiring complexity
- Higher risk of faults
- Less safety
Advantages:
- All components in one enclosure
- Improved safety
- Faster installation
- Cleaner system design
This is why metering cubicals are now standard in modern electrical metering systems.
