Inflatable Ultralight Non Partial Discharge Testing Transformer is a high-end testing transformer which firstly marketed in China by our company. The high-light characteristic of the equipment reflects the smallness in size, lighter in weight clean, oil-free, unnecessary static of field investigation, longer working life without maintenance and slightness in non-partial-discharge. It is used for the insulators' voltage-resistance testing.Major technical characteristicVoltage unit50.100.150.200.250.300.500kVCapacity unit3.5.10.15.20.25.30.50.100.150.200.300.500.1000kVAInput voltage220, 380V uniphase 50HzImpedance voltage6%≤No-load current8%≤Wave form distortion3%≤Annual gas leakage1%≤

A key feature of our rotary switches is their simple mechanical design which results in conservative stress levels for trouble-free, long life use. In addition, each rotary switch has a reinforced chassis design utilizing G-10 or G-11 fire retardant anti-tracking coated epoxy glass insulation. G-7 silicone glass is used for special applications where RF or high temperatures are involved. Heavy duty contacts, specifically designed to minimize corona in the Ross rotaries, are made of highly conductive yet weld resistant alloy with high contact closing force. This high force gives our rotary switches high momentary current capability and a reputation for their ability to withstand high shock and vibration as well as other severe environmental conditions. Ratings to 150kV, to 200A. When immersed in insulating oil, fluid or gas, the voltage withstand value is at least doubled and the interrupt capability is much greater. In a gas atmosphere, no modification is required. However, immersion in oil or fluid may require modification in some cases, at an extra cost (optional). Each unit is either manually or electrically operated. One SPDT contact is standard on most units. The auxiliary contact is used as an interlock for protection against "Switching Hot".

Mess- & Prüfsysteme GmbH
Our high-voltage coupling capacitors are a main component of our partial discharge test stations. They serve to decouple the partial discharge impulses and act as a voltage divider, the output voltage of which is matched to our partial discharge measuring devices (with integrated voltage measurement) and peak voltage measuring devices. These high-voltage components are also available separately in their various designs, sizes, capacities and voltage ranges.

Wuhan Sangao Electrical Test Installations Limit Co.
SF6 gas -filled testing transformers are especially designed for GIS in the factory and on-site test, and for testing all GIS switchgears and GIS components such as insulators, insulating tension pole, GIS voltage transformer and so on, the PD test can be performed under the general environment because of the merits of encapsulation, the PD level of our equipment can be lee than 3pC, and it can be added a HV bushing to perform the withstand voltage test at the same time. Small and compact dimensions resulting in minimum space requirements. Light-wight components. Rugged construction to withstand long transportation stresses. Direct flanging to the test object. High safety for tester because of encapsulation of all HV parts. Large range of application in conjunction with HV bushing for withstand voltage test. Built-in HV measuring capacitor and coupling capacitor. Built-in HV disconnecting switch to separate multipath test object connector to ensure the safety of HV testing.
