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.

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).

B-1020-C -
ROSS ENGINEERING CORPORATION
These supply 120V or 240V AC continuous power for equipment that must operate while at a high voltage to ground or power source. For example, a fiber optic transmitter at the HV level for waveforms to be received and measured or recorded by grounded instrumentation might be powered by an isolation transformer secondary to primary either insulated by potting, oil or air. The low dielectric constant of air insulation provides lower capacitive coupling between the secondary and the primary or ground than would solid or oil insulation. The lower capacitance provides better isolation both at line frequency and especially at high frequency voltages such as lightning or switching transients.

Gopal Electronics
Three Phase Power Analyzer PA700TFT is multi-range power Analyzer with basic 0.05% R+R accuracy. 8 range of voltage, 8 range of current and total 64 range of power and power factor gives more accurate result at low power factor. It has waveform mode to check the waveform of voltage and current. As well it has B/H curve mode where user can check live b/h curve of the transformer under test. The gap less four-quadrant power measurement technique gives better accuracy at distorted waveforms or AC drive (VFD) operated power supply.

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.
