LFG-200 Audio 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: - tracing – determining the route and burial depth of underground cables and other hidden utilities; - fault location – interphase and phase-to-sheath short circuits faults pinpointing; - cable identification – identifying a correct cable in a bunch. UNCOMPROMISED POWER 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. WIDE SELECTION OF OPERATING FREQUENCIES 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. AUTOMATIC IMPEDANCE MATCHING 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. MULTI-FREQUENCY MODE 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. PULSE MODE Operating LFG-200 in the pulse mode provides an easier signal detection at high level of extraneous noise. INFORMATIVE OLED DISPLAY 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. INTEGRATION WITH CABLE TEST VANS The unified casing size allows for easy installation of the generator LFG-200 in the rack of a cable test van (ETL-series).
