JHPD-10 -
Xiamen Jiahua Electrical Technology Co.,Ltd
JHPD-10 quickly and accurately detects various kinds of partial discharge signals that occur with insulation defects in GIS. Attached on the surface of GIS the detector collects the inside discharge signal of impure gas, suspension potential and solid insulation material. The diagnostic software analyzes the fault character and locates the fault to avoid electricity accident. The device is for daily patrol inspection with high efficiency and easy operation features. Designed with two UHF signal channels, one detects the partial discharge signal; another excludes the disturbance signal like corona discharge in the air and mobile phone communication.

Environment Associates Inc.
When you want to test your product for extreme space conditions, that include temperatures from 155°C to -175°C at space vacuum altitudes, Environment Associates is your solution. Using this test to determine the unique failures of space mechanisms that orbit the earth is key in improving system reliability. Thermal vacuum testing is similar to thermal cycling but adds deep space vacuums for detecting corona/arcing and intermittence and increases a product’s out-gassing. The key failure modes found during this test are: 1) electrical iIntermittence, 2) thermal control issues, 3) arcing, 4) corona, 5) material out-gassing, and more, to determine a product’s flight-worthiness for workmanship and processing issues.

ROSS ENGINEERING CORPORATION
Extra high voltage, low corona, grounding relays of the air insulated type. Peak test ratings up to 300kV and 100 amps continuous. Units can be operated either by solenoid, motor, or air cylinder, with spring or gravity return. All models have spherical contacts. When voltage transient limiting is required, some models have an adjustable sphere gap. Also available are units with built-in high voltage discharge resistors with energy dissipation capabilities from 50 to 10,000 ohms. Some units can be reduced in height if full line to ground voltage is connected to the top high voltage contact only and the other high voltage terminal is operating at, or near, ground potential. Line to ground voltage can also be increased by adding insulation between lower high voltage contact and ground. Normally mounted base down. Base up mounting if specified.

Fivestar HV Testing Equipment Co., Ltd.
FSHV offers three different types of AC voltage test systems, the conventional type is AC test transformer design, mainly for testing objects of medium & low capacitance products, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers). Another is AC resonant test systems, according to series resonance circuit XL=XC (2πfL=1/2πfC), by setting F frequency of power supply or L inductance of reactor, generate a pure sinusoidal waveform of the test voltage, and the required input power is only 1/Q. Variable frequency type operates in a frequency range from 20Hz to 300Hz, ideal for field commissioning test of power cables and GIS/GIL. Variable inductance type outputs continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.

ROSS ENGINEERING CORPORATION
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".
