Short Circuit Locator for Power Cables
A910
-
The A910 is a short circuit locator designed for fault location in power cables. The instrument measures the ratio of the resistances of the two sections of failed conductor using a four-wire "Kelvin" connection, thus eliminating errors associated with contact resistances of the test leads. With the A910 you can determine if the cable has more than a short and locate the first and the last fault. The instrument locates fault with an insulation resistance up to 5 Mohms in cables that have a total resistance greater than 5mohm (approximately 90 m of 300 sqmm cable) and less than 30 kohms. The distance to fault is measured as a percentage of the total length of cable and is displayed on a large LCD display.

Voltage Probe
KHZ43201
-
Beijing KeHuan Century EMC Technology Co,.LTD
The KHZ43201 voltage probe is a standard low resistance test probe, which meets the technical requirements for this product in the CISPR16-1 and CISPR14-1 test equipment. When measuring the interference voltage of the power grid, the artificial power supply network cannot be used at the load port, and sometimes it is necessary to use a voltage probe to measure the interference of the signal port, the load port, and the antenna port. The input impedance of the voltage probe to the ground wire is greater than 1.5KΩ, which can protect the input terminal of the receiver.

Thumpers and Cable Fault Location
-
Cable testing can be broken down to different steps of the process, starting with a time domain reflectometer test to look for an incident signal on the line or, in some high resistance situations, VLF testing. These tests will identify a fault, allowing you to move on to pre-locating it. In some low resistance faults this will occur alongside the identification via the TDR.

Cable & Insulation Testers
-
A cable insulation resistance test is a test that is performed by applying 500 V or more between the conductor and ground and measuring the resulting leakage current. An insulation resistance tester is a test instrument that measures current that leaks through the insulation into ground. Insulation resistance tests can be performed with insulation multi- meters (IMMs) or megohmmeters. Insulation resistance testers are calibrated to display megohms (MΩ) of resistance. A satisfactory insulation resistance measurement should be in millions of ohms.

Tap Changer Analyzers & Winding Ohmmeters
-
Winding resistance test of inductive test objects, such as power transformers, is one of the most effective non-intrusive ways of checking its condition. Due to their advanced design, DV Power winding resistance meters provide high test currents (up to 100 A DC) and high accuracy (up to 0.1%) within light and portable test instruments. In addition to winding resistance measurement, it is also possible to perform simple, quick and reliable transformer on-load tap changer condition assessment by recording the test current during tap changer operation, also known as DVtest. Because of that, problems with a tap changer connection, contacts, and switching procedure can be detected.DV Power winding ohmmeters consist of single-phase RMO-T and three-phase TWA series. Models from the TWA series are designed for six-winding resistance measurement of power and distribution transformers, with only one single-step cable setup. As a result of reducing the total test time, it enables significant saving of time and money.Typical application areas of these instruments are high-voltage substations and industrial environments. They are intended to measure the resistance of:Transformer windingsOn-load tap changersGeneratorsElectrical motorsHigh-current bus bar jointsCable splicesWelding joints

Electrical Safety is the most primary and essential product conformity requirement for any product that uses electricity. The clauses of safety testing of electrical products laid by worldwide agencies such as UL, CE, BIS, etc. are stringent. The products need to pass through tests such as the high voltage test, insulation resistance test, earth bond test, leakage current test and so on. And to conform to such tests, SCR Elektroniks have developed for the testing of Geyser. In addition to the conventional safety tests, test for performance is also included.

Handheld Turns Ratio & Winding Resistance Tester
TWR-H Series
-
Handheld TWR-H device is DV Power single-phase instrument designed for measuring transformer winding resistance and turns ratio.The instrument has two output DC sources for measuring transformer winding resistance. The first DC source can output up to 2 A DC and is used for injecting current to the transformer’s high voltage winding. The second DC source can output up to 10 A DC and is used for testing the transformer’s low voltage winding. This is especially useful when measuring winding resistance of distribution transformers. These transformers have large turns ratio and therefore a big difference between resistances of high voltage and low voltage windings. Upon the winding resistance test, it is also possible to demagnetize the transformer core. The demagnetization process is completely automatic and safe.Together with the turns ratio, the instrument also measures excitation current and phase shift. This enables detecting transformer core or winding turns failures which cannot be spotted by measuring turns ratio only. The instrument can output test voltage up to 40 V AC for this test, but it can also output a very low test voltage of 1 V AC which is necessary for turns ratio verification of the majority of current transformers.TWR-H is powered by an internal Li-Ion battery. Up to 100 tests can be performed with a fully charged battery.
