Transformer With Built-In AVR

HT AVR (High Tension Automatic Regulator) Upto 5000 KVA

Servokon offers precision engineered state-of-art HT Servo Stabilizer (HT AVR), as the name suggests this AVR operates "on load", continually and directly on the HT line giving stabilized HT voltage output. The fluctuating HT voltage from grid supply is initially controlled by the HT AVR with accuracy of +/-1% and then fed to the transformer resulting in constant LT output within +/-1% accuracy. This can be understood better by the schematic diagram shown below:

Transformer with Built-in AVR

Servokon offers precision innovative state-of-art Transformer with built-in AVR, which is combination of HT AVR and a standard distribution transformer. The fluctuating HT voltage from Grid supply is initially controlled by the HT AVR with accuracy of +/-1% and then fed to the transformer which transforms in into its standard ratio to LT voltage. Subsequently, stabilized HT voltage will result in stabilized LT voltage with an accuracy of +/-1%. Basically input will be 11/33kv and the output will be LT voltage with +/-1% can be obtained through a single product. This can be understood better through the following schematic diagram given below:

Advanced Voltage Regulation

The integrated Automatic Voltage Regulator proactively stabilizes fluctuating input voltages within a 20% range, offering precise control and output regulation accuracy between 1% and 2%. Rapid response electronics ensure stable power is delivered in under one second, protecting sensitive loads and improving operational efficiency.


Reliable Construction & Safety

Constructed using high-purity copper windings and silicon steel cores, the transformer ensures optimal conductivity and durability. It is insulated to Class F or Class H standards and meets stringent IEC and IS quality requirements, providing protection up to 35kV dielectric strength and safe operation even in demanding environments.


User-Friendly Display & Alarms

A digital voltmeter and ammeter provide real-time monitoring of voltage and current. The transformer features an integrated multi-level alarm system, offering instant notifications for overload, phase failure, and voltage anomalies. This proactive alerting simplifies maintenance and boosts system reliability.


Customizable Power Ratings

Available in single or three-phase configurations, our transformers cover a wide capacity range from 1kVA to 2000kVA with customizable voltage outputs and dimensions. The robust enclosure (IP23/IP44) and mounting flexibility make it suitable for varied indoor and sheltered outdoor uses.
