Cylinder Type Test Transformer (HCTT)

AC Test System - High Voltage Cylinder Type AC Test Transformer ( Up to 2250kV )

Application:
Coventional AC Test System are especially designed for testing objects of medium capacitors. These systems are particularly suited for tests requiring stable voltage even if the load changes under voltage ( corona, wet & pollution tests ) or when the load is inductive ( include voltage transformers ). The possibility of stacking several of these transformer modules allows reaching very high voltage levels by keeping reasonable floor space.

System Configuration:
* Test Transformer(s)
* Coupling Capacitor / HV Divider / HV Filter
* Power Line Filter
* Regulating Transformer
* Compensating Reactor
* Switchgear Cabinet
* Control System

Condition:
* Use environment: Indoor or Outdoor
* Extreme temperature for HV components: -5Degrees Celsius+40Degrees Celsius* Height above sea level: ≤ 1000m for each add. 100m, the HV rating must be decreased by 1%
* Relative humidity in main hall under non conditions < 90% ( at 20Degrees Celsius )
* Does not have the fire and the explosion material
* Non-electric condition dust
* The waveform of the supply voltage is the actual sine wave, waveform deviation factor <3%
* Equipped with a realiable grounding point, earth resistance <0.5Ω
* Very low partial discharge

Service:
* Installation
* Delivery test and field test
* Training
* Technical support
