LOW FREQUENCY GENERATOR
LFG-200 is a cable test van-mountable signal generator used as part of a cable tracing and fault location set for the following applications:
Compared to other generators of its class, LFG-200 is characterized by increased output power (up to 200 VA) enabling a significantly larger location range in comparison with analogues. This advantage makes it possible to accurately pinpoint faults in the utilities buried deeply in wet soil and ensures consistent tracing results even at strong inductive interference levels.
Output signal frequency may be selected from a set of 12, which can be either default or by customised at customer’s request. A large set of frequencies allows to use the generator with almost any locator operating in the low frequency range.
The automatic impedance matching provides the maximum signal power in a wide load resistance range (0.5 ... 1000 Ω). This feature significantly improves the quality of location when tracing longer lines and/or operating in difficult conditions.
A complex output signal can be formed by adding two or three operating frequencies together.
Two-frequency signal is used for tracing utilities with a possibility to determine their burial depth.
When three-frequency signals are generated, it is also possible to fine-tune the receiver during tracing.
Operating LFG-200 in the pulse mode provides an easier signal detection at high level of extraneous noise.
The generator is fitted with a monochrome OLED display featuring convenient graphical indication of the operating mode, signal power, current, voltage, and other operating parameters.
