While it is possible to obtain high quality injection transformers with bandwidths as wide as 1Hz to 5MHz or more, in some cases this is still insufficient for some tests. For example a typical heater control loop might have a bandwidth of less than 1Hz while some linear regulators and opamp circuits can have bandwidths of up to 100MHz or in some cases even higher. For these applications, a solid state injector can provide the necessary bandwidth. A solid state injector can perform at DC, while the upper frequency limit is dictated by the components selected and the printed circuit board material and layout. It is possible to obtain a solid state injector with a working range of DC – 200MHz, though above 50MHz the interconnection between the injector and the circuit being tested can become quite critical. It is essential that ripple from the injector power supply does not dramatically degrade the dynamic range or the signal to noise ratio of the measurement. The resulting plots are often much cleaner when using a solid state injector than with a transformer injector.

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

TH2521 -
Shenzhen Chuangxin Instruments Co., Ltd.
TH2521 AC Milliohmmeter is a high-performance and intelligent tester widely used to test contact resistance, internal resistance and battery voltage. The application of constant current source with 1kHz frequency can greatly eliminate the potential error caused by thermoelectricity on DUT. This meter has the function to automatically detect contact failures on test cable. At the range of 30mΩ, basic R resolution can reach 1μΩ. It is applicable for transformer, inductance coil copper resistance, relay contact resistance, switch, connector contact resistance, wire resistance, PCB line and via reistance dan metal defect detection, etc. In the mean time, signals, such as HIGH, LOW, PASS, can be output through HANDLER interface, thus it is very convenient to be used in automatic production line.
