LFG-50 & PT-14 Сable tracing and fault location set, can be used for locating as well as tracing underground metal communications, such as any cables with metal cores as well as metal pipes. In addition, it provides operator with a quick detection of short circuits on cables as well as with an identification of a cable in a bunch.
LFG-50 is a 50 W low frequency generator with ability to inject a signal of three frequencies via direct connection to an object or via internal transmission loop antenna, which is built-in a cover lid. Basic frequencies are 491; 982 and 8440 Hz. There are options of using a single-frequency or multi-frequency signals at the output.
The power of the low frequency generator LFG-50 output signal can be adjusted up to 50 W with 2.5 W steps. This signal can be transmitted constantly or broken into separate blocks of 50 % duty cycle with 1 s repetition rate.
A load matching is made automatically. Main parameters, such as output power, load impedance, selected frequency are shown on OLED display. If a load is higher than 1000 Ω LFG50 automatically switches into output voltage setting mode. The output overload protection will trip, when operating on short-circuit loops (lower than 0.5 Ω).

Automatic circuit breaker tester UPA-3 is designed for testing and ampere-second characterization of automatic AC current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switching interval.
Circuit breaker tester UPA-3 is a mobile device, which could be easily transported to a required testing location.
Circuit breaker tester UPA-3 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (RNO or VR) or through a built-in thyristor controller.
VLF-60 Cable Insulation Tester by KEP is a very low frequency high potential tester that ensures efficient testing and fault location on medium voltage cables.
Testing principle
Very low frequency (VLF) testing involves applying frequency in the range of 0.01 to 0.1 Hz to the cable under test, which is non-destructive to insulation of proper quality, but is enough to detect cable faults. Compared to DC cable testing, which can be damaging to good insulation, VLF testing does not have such a detrimental effect on the cable being tested and does not generate any travelling waves.
Main features
Efficient non-destructive cable withstand testing
Portable, perfect for field testing
Fully automatic testing cycle
Automatic discharging
Easy maintenance due to solid-type insulation system
Breakdown voltage measurement and load recognition
Easy-to-use software
Does not need an external PC
LCD touch screen
The insulators testing device HVTS-HP is designed for testing the insulation of power cables and solid dielectric with the rectified voltage of up to 100 kV, as well as testing solid dielectrics with the sinusoidal voltage of up to 100 kV, 50 Hz.
The main difference between series devices Cable test and diagnosis system HVTS-HP devices from Portable Hi pot Tester HVTS-70/50 is the increased power output. There are two standard versions: 7.5 KVA and 17.5 KVA.
SWG-12 Mobile Cable Test and Fault Location System - is a complex solution for safe, fast and easy locating a faulty place on low and medium underground voltage cables. It includes a powerful high-voltage unit, which has a test, burn and surge generation modules, and a time-domain reflectometer for locating faults on cables.
Main features:
- Suitable for portable application
- Easy to operate
- Multiple fault location methods included
- 10.4 High-contrast color TDR display
- Improved convenience for operator
- Heavy duty
The high-voltage unit of the system provides with high-power up to 1100 Joules surges at 3; 6 and 12 kV ranges. At each range, the output voltage is smoothly adjustable. The rate of surge waves can be smoothly adjusted. The single manual shot option is also included. The DC output mode is provided for quick fault diagnostics. The 100 mA burn mode is available.
Digital Impulse Reflectometer (TDR) provides you with 10.4-inch bright high-contrast TFT display with touchscreen. The 800 Ã? 600 pixels resolution makes the picture sharp. The touchscreen allows an operator navigate through the menu fast and easy. An alternative way of navigation is included. It is provided with a control knob.
Reflectometer RIF-9 integrates a multiple ways of fault prelocation. It can be used either as a standalone device in TDR mode or in a conjunction with HVmodule, working in arc reflection mode.
Reflectometer RIF-9 has USB interface. The package content includes software for PC (optional), which allows working with saved reflectograms. The firmware can be easily updated through USB interface by inserting a flash drive.
Oil testers bring out accurate and repeatable results of measured breakdown voltage. Fast high-voltage switch off time makes it possible to carry out test of dielectric liquids, which are easily destroyed under such influences.
The internal design of olt testers combined with a use of automatic high voltage breakers, cutting off supplied voltage if tester?s lid has been opened during the test, provide operator with high level of safety.
Testers are fully equipped and are ready for operation right after unpacking. They come with a test vessel (iec 60156 ? basic configuration) with vde 0370 mushroom-shape electrodes. A gap between electrodes is easily regulated with a use of pass-no pass gauge, which comes in pack.
A-series provides with fully automatic test procedure according to selected standard (basically iec 60156 and gost 6581 settings are preloaded). It has a built-in printer which is able to print a test report after procedure is done. Test results are saved into non-volatile memory of olt oil tester. A pc-connectivity makes it easy to collect data from olt oil tester, save and store them as well as print a fulfilled report. Test voltage is being measured directly on electrodes. This fact combined with a true sine voltage shape (independent from supply voltage shape), increases repeatability and accuracy of measurements.
Test vessel for this series goes with magnetic stirrer, which stirs a liquid between two measurements.
Main features:
