SparkFun Electronics
The SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying, this preprogrammed device can also be used for autonomous driving, navigation, asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch, two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth® connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.

Fivestar HV Testing Equipment Co., Ltd.
Impulse voltage test systems are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), insulators, arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/50μs), chopping lightning impulse voltages (LIC, front time 1.2μs, front, crest or tail chopped), and switching impulse voltage (SI, 250/2500μs) in accordance with IEC 60060-1; as well as IEC 60076-3 for transformers, and IEC 62067, 60840 and 60502-1 for cables), etc. And it can be used for steeping and oscillating impulse test by adding some extra equipment.

HIGHVOLT Prüftechnik Dresden GmbH
The TE measurement complements the high voltage test and is part of the routine and type testing of numerous electrical devices. It is one of the most important non-destructive methods for detecting faults in electrical installations. The breakdown of an insulating material usually occurs at an internal weak point, which usually already shows a partial discharge activity in advance. For this reason, measuring partial discharges can help prevent costly damage. The TE measurement is thus used for quality testing and diagnosis in the factory as well as during on-site testing of cables, GIS, power transformers and transducers or rotating machinery and their components

ENVI -
L3Harris Geospatial Solutions, Inc
ENVI is the industry standard for image processing and analysis software. It is used by image analysts, GIS professionals and scientists to extract timely, reliable and accurate information from geospatial imagery. It is scientifically proven, easy to use and tightly integrated with Esri’s ArcGIS platform.ENVI has remained on the cutting edge of innovation for more than three decades due in part to its support of all types of data including multispectral, hyperspectral, thermal, LiDAR and SAR. ENVI makes deep learning accessible to people through intuitive tools and workflows that don’t require programming. ENVI geospatial image analysis can also be customized through an API and visual programming environment to meet specific project requirements.

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.
