Low Frequency Generator Lfg-50

Supplier From Ukraine
Jun-11-19

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).

MAIN FEATURES:

Portable and lightweight
Moistureproof and dustproof case
Advanced LiFePO4 internal battery with fast charging option
High-contrast graphic OLED display
Multifrequency operation
Operating frequencies can be changed upon request
Internal transmission loop antenna
Automatic load impedance matching
Ability to work with energized 0.4kV cables (inductive connection)
Overload protection
Сable locator PT-14 designed for fast and accurate searching for power cables and other communications, identification of coating defects and the depth, followed by mapping.

Products Introduction
The power department did some tests to solve some problems. According to theories and test results at home and abroad, the 50KV Very Low Frequency high voltage generator withstand voltage test can solve this problem. Its advantages are that not only the test results are the same, but the instrument size is small and the weight is greatly reduced.
