Advantages of Voltage Transformer
Safety
They significant enhance safety by stepping down high voltage to lower manageable levels that allowing for safe measurement with standard instrument this protects both prosomal equipment from dangerous high voltage exposure .
Accurate voltage measurable
Vt or pts. Provide high accurate voltage measurement which are crucial for monitoring and controlling electrical system .The precision is essential for maintaining system stability and preventing equipment damage
Isolation
They electricity isolate measuring instrument and protective relays for the high voltage circuits minimizing the risk and damage to these devices
Protection
Pts play a vital role in protection system by providing accurate voltage signals to protective relays enabling them to detect respond to abnormal condition like over or under voltage
Enabling metering
They allows fr accurate metering of high voltage circuits which is very important for billing purpose with inn power distribution
System monitoring
They rare a viral part of power system monitoring which allows for the detection of system and the maintenance of stable power grid

Types of Voltage Transformer
Dry-type voltage transformer
It is insulated by ordinary insulating material impregnated with insulating varnish, and is mostly used at and below low voltage levels.
Pouring insulation voltage transformer
It is molded by epoxy resin or other resin mixed materials, and is mostly used in voltage levels and below.
Oil-immersed voltage transformer
It is insulated by insulating paper and insulating oil. It is the most common structural type in our country, and it is often used in voltage levels and below.
Gas insulated voltage transformer
Mainly insulated by gas, mostly used in higher voltage levels.
Features of Voltage Transformer
JDZW-35 voltage transformer can be used to measure, monitor and relay the voltage of incoming and outgoing lines. It can accurately convert 35kV high voltage into low voltage, provide reliable voltage signals for various measuring instruments, protection devices and control systems in the substation, and ensure the safe and stable operation of the substation.
Core
The transformer core is built of laminated magnetic material such ion or steels o create a low reluctance path for the magnetic flux , hysteresis and eddy current losses are minimized by the design of the core
Primary winding
The high voltage line connected in parallels with the transformer primary winding requires parodic monitoring the primary is typically built of few round of think copper wire or bus bars to a accommodate large of current
Secondary winding
The secondary winding of the transformer in sa connected to measuring instrument such as a voltmeter or protective relay . The number f turns in the secondary winding is determined by the ratio of high voltage to the low voltage required by the measuring instrument
Insulation
The primary nad the secondary winding of the transformer should be electrically isolated from one to another and t able high voltage paper oil and resin are typically material
Terminal
The the primary and the secondary of the transformer are connected to the high voltage line and measuring equipment respectively using terminals the terminals need to to built to resist high current and voltages levels
Protective cover
A protective cover is typically place dover the transformer to guard against environmental elements like moisture and dust and prevent unintentional contact with the high voltage components
Providing isolation between circuits: Another common use for voltage transformers is to provide isolation between circuits. This is typically done to prevent electrical interference caused when one circuit interferes with another.
Providing voltage regulation: Another common use for voltage transformers is to provide voltage regulation. This is typically done to ensure that the output voltage of a power supply is consistent and within a required range.
