Servo Voltage Stabilizer and Isolation Transformer

A : Servo Voltage Stabilizer :
Ganpati Electricals (Pvt.) Ltd. is well known for its designing ability of 3-phase oil cooled Servo Voltage Stabilizers in India and abroad under the brand name "GE POWER".

Why Use Servo Voltage Stabilizer? :
Many times it has been seen that a minor fluctuation in voltage can cause the equipment to malfunction or even break down. Servo Voltage Stabilizer prevents all this by controlling fluctuations in input voltage and providing constant output voltage. GE POWER stabilizers are designed to suit input voltage requirement of individual customers.

Single Phase Servo Voltage Stabilizer :
Single phase stabilizers are distortion free and give perfectly stable output even under severe conditions of unbalanced voltage. These are available to suit the input voltage variation (starting 120V) of individual customers, in capacities up to 30 KVA, all giving output voltage of 280 +/- 1%.

Three Phase Servo Voltage Stabilizer :
Oil-cooled stabilizers are available in capacity up to 2500 KVA and air-cooled stabilizers are available in capacity up to 40 KVA. These can be either of Variac-type or Roller-type. These have input voltage variation of 240-470V, 270-470V, 300-470V, 320-470V, 340-470V and 360-470V, and output voltage of 470V +/- 1% or as required by the customer.

Special Features :

Design	:	Computerized
Efficiency	:	Over 98%

Features on Demand :
Some of the special features like the following can be included on demand.

• High-low voltage cut-off to automatically switch off the unit when the output voltage goes above or below a certain preset voltage limit.
• Overload protection to switch off the unit when the load current value goes higher than the rated value.
• Manual by-pass facility.
• Single phase prevention for 3-phase units.
• Reverse phase sequence protection for 3-phase stabilizers.
• Built-in spike suppressor.
• Audio-visual alarm.

Applications :
Three-phase oil-cooled Servo Voltage Stabilizers have unlimited applications in the offices, commercial buildings, telecom industry, textile industry, IT industry, call centers, research laboratories, hospitals, air-conditioning plants, hotels & restaurants, malls, industrial lighting loads, escalators & elevators and offset printing machines etc.

Advantages :

• Quick, steady and accurate correction of voltage.
• Balanced output voltage, irrespective of unbalanced input.
• Reduced heating and minimum losses.
• Overall energy saving and reduction in electricity bills.
• Reduction in breakdown of electrical / electronic equipments.
• Increased life of bulbs, tubes, motors and other accessories,

B : Isolation Transformer :
Isolation transformer is designed to provide electrical isolation without stepping voltage and current either up or down. It decouples the two circuits and prevents passage of line voltage transient, spikes and galvanic leakages from reaching the sensitive or critical equipment like computers and its peripherals, medical instruments and digital communication & telemetry systems etc. It is used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected together.
