H.T. Transformer With Built-in Automatic Voltage Stabilizer

Even after the installation of standard off circuit distribution transformer, the voltage fluctuation on the LT side persists due to limited range of voltage correction of the transformer. To control the voltage fluctuations, it is ideal to install Servo Controlled Automatic Voltage Controller either on LT side or HT side. SERVOMAX make Transformers with built-in rolling contact type AVR suitable for indoor/outdoor installation, copper wound HT Two-in-one system is a revolutionary landmark in the industry when it comes to voltage regulation and stabilization. Even after the installation of standard distribution transformer the problem of low/high voltage on the LT side persists, resulting in improper operation of the electrical equipments, premature failure & production loss of a plant. The standard off - circuit tapping of transformers can correct limited voltage variation and cannot regulate the voltage while in ‘On Load’ conditions. We have developed state of the art technology two-in-one system with Transformers having built-in HT Automatic voltage regulator that operates on load, sleeplessly & gives stabilized voltage on the LT Side. The equipment is basically a combination of HT AVR with a standard distribution transformer. The Fluctuating voltage from grid is initially controlled by the HT AVR and then fed to the transformer resulting in the constant L.T. Output within +/- 1% accuracy and the biggest advantage being its robust design ; Lesser losses & more efficiency make the distribution transformer to utilize up to 100% capacity. H.T. Transformer with built-in Automatic Voltage Stabilizer: 3000 kVA The unit consists of: 1. Step down double wound in copper construction 2. On load stepless rolling contact type voltage regulator 3. Buck/boost transformers Advantages of Built - in AVR     * Space Saving     * Better Efficiency     * Protection of Motor etc.     * Reduced Installation Cost     * Reduction in Electricity Bill    SERVOMAX H.T.

Isolation Transformer

SERVOMAX has a wide range of ISOLATION TRANSFORMERS which reduce the effects of power Line problems like noise, spikes, surges, transients and neutral, to a minimum. Power generation in our country, is no doubt good and availability of continuous power is Certainly better, but the stringent requirements of the sophisticated equipment being used today underlines necessity of clean power. Owing to inductive loads, capacitive loads, SMPS loads, electronic ballasts and with PWM Switching systems, the present AC Power lines are superimposed with dangerous spikes, Surges, transients, sags and RFI noise and harmonics. As a result failure rates of electronic equipment are on the rise. Without adequate protection, All electronic equipment is at a great RISK. Usually the failures are not seen right away. Repeated stress from normal electrical transients weaken components and lead to shortening of component life. Line noises like spikes, surges, transients and so on definitely cause stress on semi conductor components. And Machine Systems experience catastrophic program and software failures, extensive damage to PLC’s and storage media, leading to heavy losses of production, data and man-hours. With SERVOMAX ISOLATION TRANSFORMERS all types of electrical noises, particularly common mode noises, spikes, surges, and transients can be eliminated.

Our Projects

Our organization is engaged in undertaking many projects to meet the diverse requirements of the clients. The various projects undertaken by us are in association with the Vijayawada Municipal Corporation (VMC). These are meant for the pumps for power savers. The power saver installed in one of the electricity boxes at Sambamurthy Road in Vijayawada. In addition to this, the Vijayawada Municipal Corporation (VMC) is gearing up to cut down on its fat power bill by attaching power saving devices to all streetlights. In July, VMC officials allowed Servomax Precious Electronics Private Limited, a Hyderabad-based power correction & manufacturer of power saving equipment, to experimentally attach a power saver to 40 sodium vapor (SV) lamps on Sambamurthy Road. The device was installed in one of the two power boxes on the street from Alanakar to Kotha Vantena. At the end of the trial that ran for 15 days, electrical engineers of the VMC found that there was a 34 per cent fall in the power consumed by the lamps. Micro-controller timer According to Director (technical) P. Pavan Kumar, the device will have a micro-controller timer that allows lights to be switched on and switched off at a particular time. Apart from this, it is instrumental in reducing the losses in the chokes by arresting voltage fluctuations. The 220 volts that the lights require will be supplied without disturbances. The power factor is an important indicator of the effect of the load current on the efficiency of the supply system. It also increases as a result of less power consumption. Municipal Commissioner Natarajan Gulzar says that replicating this kind of experiment on a macro scale for the entire city will result in considerable saving to the corporation. “There are many firms that are ready to maintain the devices without any additional burden to the corporation. We’ve invited expressions of interest,” he says. Even if there is a saving of 30 per cent of the power consumed, it will result in a saving of Rs. 9 lakhs to Rs. 10 lakh per month, or Rs. 1.08 crores to Rs. 1.2 crores a year, says VMC deputy executive engineer (electrical) B. Srinivasa Rao.
