HVT provides you with accurate and reliable systems for measurements of test signals in laboratories, power utilities and manufacturers of electrical transmission and distribution apparatus.

	Doble Lemke PD Smart Electrical and PD Smart UHF PD Test System The Doble Lemke PD-Smart is a versatile, multi-application partial discharge (PD) analyzer especially designed for day-to-day field use. The rugged and easy-to-handle PD-Smart has a wide variety of application to include cable, transformer, rotating machine and switchgear testing. With its capability to conduct both on-line and off-line measurements, there really are few places you can't use a PD-Smart
	Doble Lemke Partial Discharge Surveying tool PDS100 The PDS100 is an RFI surveying tool that is designed for use in a live substation. Without the need for outages or special connections, the unit can detect partial discharge (PD) in just a few seconds thus making it an ideal tool for a condition based maintenance (CBM) program. Whole substations can be surveyed and analyzed. The PDS100 is the perfect tool to detect and locate sources of PD.
	Doble Lemke LDS-6 and LDS-6 / UHF PD Test System Digital Partial Discharge Measuring and Diagnostics System for industrial and general HV test floor environments. The LDS-6 is a highly sophisticated digital measuring system for the Partial Discharge (PD)detection according to the standard IEC 60270, VDE 0434 as well as various IEEE and other standards for the High Voltage Test and Measurement Technology. It meets also ICEA T-24-380 standard of the Cable Industry.
	Doble Lemke LDA-6 multichannel power transformer PD acoustic locator The LDA-6 was developed for acoustic localization of dangerous Partial Discharges inside Power transformers. Advanced algorithm allows a high precision localization of the Partial Discharge Source. A graphical user interface visualize the spatial position of the Partial Discharge Source.
	Doble Lemke LDP-5 Hand-held PD Detector The portable Differential LEMKE PROBE LDP-5 detects and locates dangerous partial discharges in HV equipment. Due to the light-weight construction, the Lemke probe LDP-5 can be used for both on-site inspections and measurements in the laboratory.
	Doble Lemke Ultrasonic PD Receiver LDA-5/S Detection of the ultrasonic sound of PD events at a resonance frequency of 40 kHz. Depending on the type of the receiver, either discharges in air (corona) or in HV equipment can be recognized, as for instance in cable accessories, power transformers and switchgears, including GIS.
	Doble Lemke PD Monitoring, PD Guard and PD Guard UHF The PD monitoring system PD-GUARD is especially developed for continuous partial discharge monitoring of high voltage equipment, such as generators, motors, power transformers in the conventional range of frequency. For the implementation of permanent UHF partial discharge measurements, the PD monitoring system PD-GUARD/UHF is used. The PD-GUARD/UHF is especially designed for continuous PD monitoring on gas-insulated switchgears (GIS) and cable systems. The decoupling of the partial discharges will be done in the UHF frequency range.
	BAUR PD Portable System  Most modern non-destructive  partial discharge diagnostics (PD) Identification and precise location of partial discharges in cable systems Measures PD levels and locates PD sources reliably over the entire cable line Very easy operation via BAUR’s diagnostics software
