Trans Power Tech - Transformers

1. WTI or Oil Immersed (Bushing) current transformer:- These Cts are used in distribution and power transformers upto 500MVA capacity and voltage class upto 400kv.

Features: 

• Mounted inside the transformer tank
• It replaces the outdoor C.T. in the switchyard hence cost effective and maintenance free
• Used for protection of high value power transformers
• C.Ts. are manufactured in single as well as multi core, multi ratio.

Details required for ordering the bushing C.Ts.

• Transformer Ratio
• Accuracy Class
• Rated Burden
• Knee point Voltage
• Excitation current i.e. imag at specified % of @vk, vk/2, vk/4
• Secondary winding resistance
• C.T. dimensions on request

Application:

• Used in distribution & power transformers, for metering & protective applications
• Our bushing C.Ts. are widely accepted by all reputed transformer manufacturers all over India

The isolation transformers are used as instrument transformers when the high voltage should be measured. The high voltage is dangerous for the person who tries to measure high voltage but it can also harm the measurement circuits. In this case, the step-down isolation transformer is used to reduce the high voltage to the safe level and for measurement range.

The Auxiliary Transformer is the Power Transformer that provides power to the auxiliary equipment of a power generating station during its normal operation. This transformer is connected directly to the generator out-put by a tap-off of the isolated phase bus duct and thus becomes cheapest source of power to the generating station.

Low Tension range includes Control Transformers are specifically used to provide control supply voltage for the control circuits. It can be produced in Three Phase and Single Phase type with capacities up to 10 kVA.
