HT AVR / Built-in AVR Transformer
High-efficiency automatic voltage regulation - delivering constant stabilized output regardless of fluctuating or irregular input voltage.
Voltage Regulation
High Tension Automatic Voltage Regulators (HT AVR)
ABC HT Automatic Voltage Regulators are compact, high-efficiency servo voltage stabilizers engineered to protect heavy-duty industrial machinery and downstream electrical equipment from destructive grid fluctuations. By maintaining a highly stable and continuous input voltage, these systems prevent equipment breakdown while driving down electricity costs through minimized power losses.
Key Technical Specifications
⚡ Optimized Efficiency & Savings
Compact design minimizes internal core losses, dramatically lowering overall facility electricity consumption.
🛡️ Instantaneous Grid Protection
Responds within 10 milliseconds to correct low or high voltage spikes before they can reach and damage sensitive electronic systems.
🔧 Low-Maintenance Operation
Automated microcontroller-based design ensures seamless, trouble-free voltage regulation with very low maintenance overhead.
Protection
High Tension Air Circuit Breaker (HT ACB)
The HT ACB is a path-breaking protection panel conceptualized for small industries, commercial complexes, schools, hospitals, and residential buildings where electrical safety is paramount. Functioning as a 3-pole switch paired with a current-limiting CT, IDMT relay, and a Power Pack, it safely breaks 11 kV supplies in HT installations. It manages full-range overloads and short circuits on loads up to 1 MVA capacity - an elegant, space-saving alternative to a traditional VCB or pole-mounted Gang Operated Switch (GOS).
Performance Parameters
🛡️ Full-Spectrum Grid Protection
Micro-controlled IDMT relays provide comprehensive automatic defense against overloads, short circuits, earth faults, and transformer operational stresses.
⚡ Advanced Arc-Quenching Design
Housed in a secure metal-clad enclosure, its unique arc-quenching mechanism reliably breaks both typical operating currents and severe fault loads.
🔒 Integrated Safety & Interlocks
Built-in Earth Switch for safe cable grounding, fortified with mechanical safety interlocks to prevent hazardous accidental switching.
