The AMIC-30 insulation tester is a small portable meter designed to measure insulation resistance in electrical and telecommunications installations, cables, motors, transformers and other equipment. The test voltage can be programmed in steps from 10 V to 1000 V. The instrument can measure both insulation resistance over a wide range (0,1kΩ...100GΩ), and insulation leakage current, capacitance and other parameters. All test results can be stored in the internal memory and sent to a computer via the included wireless USB receiver. The meters are supplied with rechargeable Ni-Cd batteries.

Signals & Systems India Private Limited
In order to implement a 100 % stator earth fault protection based on subharmonic injection, a 20Hz voltage is injected into the generator star point. The 20-Hz generator SGEN-1001 is used in combination with the Band Pass Filter SBPF-1001 in the Stator Earth fault protection. The injection can be performed by connecting the SGEN-1001 and the SBPF-1001 to the load resistor of an earthing or neutral transformer. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. From the driving voltage and the fault current, the protective relay determines the fault resistance.

PDMonitor -
Power Monitoring and Diagnostic Technology Ltd.
The PDMonitor, which utilizes Ultra High Frequency (UHF), Acoustic Emission (AE) and High Frequency Current Transformer (HFCT) sensors and is designed to conduct real time online monitoring to detect and analyze potential Partial Discharge (PD) signals and insulation faults before they lead to breakdown or catastrophic failure in power assets. The system provides the developing trend of the PD, when occurring, as alarms in real time, thus helping to predict the insulation degradation status of the asset, prevent sudden accidents, and provide an effective database for Condition-Based Maintenance (CBM) of power assets.

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
