Megger Group Ltd.
Handheld online PD substation surveying system. The UHF PD Detector is the ideal tool for quick, non-invasive surveys in MV and HV substations and should be part of the toolkit for all maintenance and service teams. Due to its high measurement bandwidth, the UHF method provides accurate local online partial discharge (PD) measurements on HV components such as cable end-terminations, surge arrestors, voltage transformers and isolators.

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.

Yangzhou Power Electric Co., Ltd
Testing of certain apparatus requires much high voltage or current that a straight AC test system is not sufficient. Thus resonant test reactor with a variable core is needed. The main advantage of such test systems is lower input power and larger output power. The resonant test system is designed to compensate capacitance in the testing circuit precisely by tuning inductance of the test system. AC resonant test system is used for factory testing of middle, high and ultra-high voltage cables, capacitors, generators, motors, power transformers and gas-insulated switchgears.

HFCT Ø 140mm -
Techimp HQ S.r.L
Techimp Clamp High Frequency Current Transformer model 140 is an inductive sensor for partial discharge measurements. It is suitable for online /off line PD tests on : large diameter cables ; grounding rod bar ; etc. A TNC termination is available to connect the Clamp HFCT 140 to the TechImp PD analyzer : PDCheck , PDBase etc. The arrow indicates the requested input current (Iin) direction to get coherent output voltage (Vout) polarity respect to ground. When the sensor is installed with the arrow directed to ground, the detected voltage signal (Vout) has the same phase of the input current (Iin).

The Motwane Manufacturing Company
Motwane is India’s first company to design and develop an intelligent digital insulation tester that conducts insulation resistance tests on high voltage electrical equipment. Products like transformers, generators, motor cables, bushings, LAs, and switchgear, are prone to gradual degradation over time due to the adverse effects of temperature, humidity, and dust. The gathered test data allows clients to verify the current quality of insulation, and take appropriate action.
