Three Phase OLTC Oil Transformer Yyn0 33kv , 5 MVA Power Transformer
1. With high requirement on the reliability of power supply;
2. With bigger voltage fluctuation;
3. Need to adjust voltage frequently everyday.
& Tap Range
on load tap changer offered, custom-made designs, rich experience
in transformer production,
various Voltage & Power available
The differences between OLTC transformer and General no load tap
1. The biggest advantage of OLTC transformer is can adjust voltage
on load under the condition
of without a power outage; But general transformer need to cut the
power first and adjust the voltage
2. The price of OLTC transformer will expensive than the normal
one, the installation cost will get higher
also. If it occurs failure, the cost of maintenance will higher as
3. OLTC transformer is appropriate for the area which with
unstable voltage supply or loading, but with
high requirement for the voltage and need to adjust the voltage
frequently. That these users should
choose OLTC transformer.
4. If the production process is continuous, but it has deviation
with the voltage, that choose OLTC
transformer will improve the reliability of power supply.
5. No need to cut power or test when the OLTC transformer running,
but NO load tap changer
transformer after adjusts tap changer manually, needs to do "
Transformer dc resistance test ".
Then it need professional person and instrument to achieve this
job. It will increase management
cost and employment.
PS: the weight and dimension just for reference, please in kind
