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.

The Eastern Specialty Company
Need an all-in-one field test kit? TESCO’s Meter Site Analyzer is the most versatile and complete tool for testing the entire functionality of transformer-rated metering installations in a convenient, portable, and ULTRA lightweight kit—only 17.8 lbs! As a utility, the vast majority of revenue comes from large customers who have transformer-rated services. At transformer rated sites the opportunity for something to go wrong is much greater than at a self-contained site. Studies have shown that at transformer-rated sites, the vast majority of issues are related to wiring, CTs, PTs and other issues. If you want to be sure that the customer is billed correctly and you are not losing revenue, you must test the whole site, not just the meter. TESCO’s all-in-one 6330 Meter Site Analyzer gives you the most versatile site testing tool available in a small, lightweight package. No other test system has the functionality of:

Test Electronics
The most important features of this burn in power supply is its ability to hold a constant output for each channel even in the event that a unit under test on one channel may short and fail. Since each channel has it''s own transformer, no glitches or voltage spikes can get into any of the other channels. This image shows the results as the second channel from the left is shorted with a small wire and the circuit breaker pops out. Used for burn-in testing and other timed testing where power isolation is required. Very basic simple circuit, see schematic below. Cleans and frees up benchtops, burn in racks and work space clutter. Available in benchtop or rackmount.
