HT AVR Manufacturers refer to companies or entities that manufacture High Tension (HT) Automatic Voltage Regulators (AVRs). Here’s a breakdown of what that means:

What is an HT AVR?

HT (High Tension): This refers to high-voltage power—typically above 11kV—used in industrial and utility-scale electrical systems.
AVR (Automatic Voltage Regulator): A device that automatically maintains a constant voltage level to protect electrical equipment from voltage fluctuations.

So, an HT AVR is used in high-voltage electrical systems to ensure that the output voltage remains stable, even if the input voltage varies.

Who Needs HT AVRs?

HT AVRs are commonly used in:

Power distribution networks
Large industrial plants
Commercial buildings
Hospitals
Data centers
Utility substations

These are essential for:

Protecting transformers, motors, and sensitive electronic equipment
Improving power factor and efficiency
Minimizing power losses due to voltage imbalances

What Do HT AVR Manufacturers Do?

HT AVR manufacturers design and produce regulators that can:

Handle high input voltage levels (often 11kV and above)
Deliver sa table output voltage
Offer features like remote monitoring, overload protection, and bypass mechanisms

Features Often Offered by HT AVR Manufacturers:

Step-up/down voltage regulation
On-load tap changers (OLTC)
Digital monitoring systems
Oil-cooled or dry-type transformers
Customized capacity (from 100 kVA to several MVA)

Types of HT AVR Manufacturers

1. Electromechanical HT AVR

- Uses servo motors and transformers to adjust voltage.
- Ideal for medium to large industrial loads.
- Precise voltage regulation, but slower response.

Subtypes:

- Servo-controlled AVR
- Tap-changing AVR

2. Static HT AVR

- Uses solid-state electronics (like SCRs or IGBTs) instead of moving parts.
- Faster response, suitable for sensitive equipment.
- Less maintenance, more compact.
- Used in data centers, hospitals, IT sectors.

3. Ferroresonant (Constant Voltage Transformer) AVR

- Uses saturable reactors and ferroresonant transformers.
- Offers excellent noise filtering and short-term backup.
- Limited to smaller capacities (not common for HT).
- Mostly used in low voltage applications, but occasionally adapted.

4. On-load Tap Changing (OLTC) HT AVR

- Uses a transformer with an on-load tap changer to vary voltage without disconnecting the load.
- Common in 11kV or 33kV systems.
- Often oil-cooled.
- Widely used in substations, industrial plants, and utility networks.

5. Step Voltage Regulators

Special type of AVR used in power distribution networks.
Operates like a transformer with tap-changing ability, regulating voltage step-wise.
Commonly used by electric utilities.

Based on Cooling Type

6. Oil-Cooled HT AVR

Uses transformer oil for insulation and cooling.
Handles high power ratings (above 500 kVA to several MVA).
Suitable for outdoor and heavy-duty installations.

7. Air-Cooled (Dry Type) HT AVR

Uses air for cooling.
More compact and maintenance-free.
Suitable for indoor installations and clean environments.
