Page 10: Putting Into Operation
GL 660-1 Putting into operation Safety No dangerous voltages are present on the generator or the receiver. Nevertheless, when operating the GEOLUX system, the following safety measures should be adhered to: v) The housing of the generator is to be earthed, both on mains and battery operation. -
Page 11: Figure 1 : Test Clip Pk 660
GL 660-1 VERY IMPORTANT Since under certain circumstances the test lead clips have to be connected directly to a bus-bar, severe danger exists in the event of a short-circuit in the test lead or in the generator. The voltages in the bus-bars would cause the test leads to vaporize and endanger the operator of the instrument. -

Page 15: Determining The Faulty Conductor
GL 660-1 Determining the faulty conductor This measurement is completely passive, i.e. the generator GLS 660-1 does not have to be switched on. After connecting the test lead, one of the clips has to be connected to system earth. The other clip is used to touch the three phase conductors one after the other (fig. -
Page 16: Safety Instruction
GL 660-1 Safety Instruction: On completion of the measurement, first remove the clip from the live cable. Only after that, disconnect the clip from system earth. Power supply of the generator GLS 660-1 The generator can be operated from the built-in rechargeable 12 V battery or from the mains. -
Page 17: Receiver Gle 660-1 - General
GL 660-1 Receiver GLE 660-1 – General The GEOLUX system also includes the receiver GLE 660-1 and the various probes for picking up the 5 Hz electromagnetic field. Description of the receiver The battery operated GEOLUX receiver is a selective, powerful amplifier unit for reception and determination of the value of a 5 Hz signal fed to the faulty cable. -

Page 19: Putting The Receiver Into Operation
GL 660-1 Putting the receiver into operation The receiver can be switched on only after the insertion of the measuring probe. Switching the receiver ON As shown in figure 5, the receiver is switched on by pressing the luminous pushbutton (28), lighting up a red lamp. Simultaneously, for approx. -
Page 20: Connection And Selection Of The Probes
GL 660-1 Connection and selection of the probes All probes have to be connected to the socket (27). (Without a probe connected the receiver cannot be switched on). The following probes are available: Receiver tongs AZK 100 as standard accessory with an internal diameter of 100 mm. -
Page 21: Pulse Mode Of The Generator Gls 660-1
GL 660-1 4.3.1 Pulse mode of the generator GLS 660-1 After switching on the generator GLS 660-1, it is automatically set to "continuous test current". This is indicated by the pilot lamp (8) which lights continuously. For an external ON-OFF switching or a timed pulse sequence through the receiver, pushbutton (11) has to be operated. -
Page 22: Automatic Pulse Mode Of The Receiver
GL 660-1 4.3.2 Automatic pulse mode of the receiver For this mode of operation, the generator has to be connected to the receiver by means of the connection lead VK 50. Instead of this 10 m connection lead, one can also use the cable drum KTG 50 with 50 m of cable. -
Page 23: Reactive Current Compensation
GL 660-1 Reactive current compensation The location of high resistance earth faults in cable systems with a high capacitance is problematic. This is due to the fact that often the capacitive reactive current is considerably higher than the test current over the fault. The compensation facility of the GEOLUX system offers the possibility of compensating cable capacitances up to 50 µF. - Page 24 GL 660-1...
