Automatic Voltage Regulators AVR

We are manufacturer and exporter of automatic voltage regulators or avr’s since last 25 years. We are located in okhla industrial area, which is the most developed industrial area in New Delhi. Before moving ahead with our range of automatic voltage regulators , we would like to share some facts. Normally in every country the electricity is generated and transmitted through a 3 wire system, which is also called balanced type supply systems. The load consists of both 1 phase equipment and 3 phase equipments which needs to be run on this 3 wire balanced system, so to facilitate the same, Delta / Star configuration transformer is used at last point of distribution network. By using the same, the 3 wire system gets converted into a 3 Phase, 4 wire system. The important issues here is that the neutral of the star side must be properly grounded in order to avoid floating or oscillation of neutral. Neutral is the key for stable electrical conditions. This condition if not taken carefully gives birth to unbalanced nature of 1 phase supply which is normally seen in our distribution networks.  Now even in above scenarios, the line to line voltages remains balanced for all practical purposes in spite of unbalanced line to neural voltages. So there is comparatively less problems in running a 3 phase loads compared to 1 phase loads.

Types of Automatic Voltage Regulators and AVR ?

UNBALANCED TYPE AVR: Widely accepted design to suit various conditions. All the phases are independently sensed & corrected. Its is a combination of 3 single phase units combined together. Suitable for both balanced / unbalanced loading & incoming voltage. So in case the load is combination of 3 Phase & 1 Phase nature or totally single phase then only unbalanced type Automatic Voltage Regulators and AVR is recommended. Unbalance type automatic voltage regulators are widely used and recommended for most application and industry.

BALANCED TYPE AVR: One phase (master) sensed & all the 3 corrected in accordance to the master phase. Suitable for balanced loading & balanced incoming voltage only. So in case all the load is of 3 Phase nature then balanced type Automatic Voltage Regulators and AVR are to be used.

How to decide the right KVA of a Automatic Voltage Regulators - AVR

Some thumb rule conversions factors for choosing the right KVA of the Automatic Voltage Regulators.

a. KVA of Stabilizer = H.P. of lift * 3
b. KVA of Stabilizer = Tonnage of A.C. plant * 2
c. KVA of Stabilizer = H.P. for Resistive loads
d. KVA of Stabilizer = H.P. or K.W./ Power factor for Reactive loads.

Ratings Available for above Voltage Regulator: 1 KVA to 1500 KVA (1 Phase / 3 Phases)
