INSTALLATION AND COMMISSIONING OF SERVO VOLTAGE STABILIZER

Voltage stabilizers are manufactured to exacting quality standards, however, in the unlikely event there may be some problems, therefore proper installation and commissioning is must for efficient operation of servo voltage stabilizer. Here we are giving some important tips for proper installation and commissioning of servo voltage stabilizer:

INSTALLATION:
The voltage stabilizer must be installed at well ventilated place, It should be installed in such a way that at least one meter space is available all around. The voltage stabilizer is dispatched in completely assembled state ready for use and only incoming and outgoing cables are to be connected by customer and the panel is required to be connected through the plug-in-cable. Two separate earth connections are to be provided at two places marked on the body of voltage stabilizer. The incoming supply of voltage stabilizer should come from incoming source via circuit breaker/mains. The output supply of voltage stabilizer should be connected to distribution cable/distribution panel through which the load is connected. The cable and cable lugs are to be connected to voltage stabilizer should be of proper rating. The voltage stabilizer does not require any foundation. However the place where stabilizer is to be placed should at least have a brick floor so that it may take its weight and it should be leveled.

COMMISSIONING:
1. Fix the panel on top of the voltage stabilizer. Connect the control cable with the panel by fixing plug in socket.

2. Open the cover of input terminal box and connect the input supply from source to the input of voltage stabilizer through connections. Lugs should be properly crimped and should be properly tightened up while connecting voltage stabilizer.

3. Open the cover of output terminal box, connect the output of voltage stabilizer through connections to the distribution panel/cable lugs should be properly crimped and should be properly tightened while connecting voltage stabilizer.

4. Connect two separate earth points to the body of the voltage stabilizer at the earth point marked on the bottom.

5. Check for insulation resistance with 500V equipment between phase and body. Minimum value should be 50megaohm. If the job is installed within one month of dispatch no IR test is required.

6.  Put control panel in auto mode and set output voltage through output voltage setting pot.

7.  Run the voltage stabilizer for five hours on No Load before connecting the load.




OPERATING INSTRUCTIONS:
1. Please check connections on regular basis for any looseness.

2. Please check the brass rods for signs of sparking caused due to lose connections, clean it and tighten it properly on regular basis.

3. After one year of use the transformer oil should be filtered on yearly basis, it will ensure longer life for voltage stabilizer.

4. You may require replacing the carbon brushes after three or five years for proper operation.

5. Oil level on the oil gauge should be checked at regular intervals.

6. Insulation resistance results should be taken at six months interval.

7. Check the temperature on the temperature meter while in use. Your equipment is designed for 50Deg above ambient temperature. Ambient temperature in tropical climate varies between 1 Deg C to 46 Deg C. If temperature regularly and frequently goes 30Deg C above ambient, kindly maintain record.

So if we follow the above instructions properly than our servo voltage stabilizer will work more efficiently as well as life our equipment will get increased.

Good post. I learn something totally new and challenging on blogs I stumbleupon every day.
It's always useful to read through content
from other authors and use a little something from
their web sites.
