MAELEZO YA UPATIKANAJI
UTANGULIZI
- HTFLEX33e is an innovative current transducer based on the operating principle of the Rogowski coil, combining friendly use with measurement accuracy. The HTFLEX33e current probe is similar to a CT or current transformer.
- The output is an AC voltage that is, after an integrator circuit, proportional to the AC value.
- The output signal is insulated from the hazardous conductor potentials and is a replica of the current waveform in the conductor. The output signal is available via a 3-pin connector (see Fig. 1 or output signal pin assignment).
VIPENGELE
- The lightweight and flexible HTFLEX33e is a current probe that may be wrapped around most conductors.
- The flexible head has a preset bend that allows the transducer to be more easily operated around the conductor (see Fig. 2).
- Its application versatility and insulation rating clearly distinguish the HTFLEX33e transducer from other current measuring methods.
- It is made of non-ferrous materials, minimizing any circuit loading due to magnetic influence.
- The frequency response of the HTFLEX33e current probe is quite wide compared to conventional CTs. This allows the user to monitor a much wider range of line harmonic components than conventional CTs allow. The transducer was designed to be very flexible, with a larger opening and a smaller cross-section compared to many conventional CTs. This allows measurements in tight places as never before possible.
- The current probe was designed to allow the operator to connect this device around a conductor without disconnecting it.
- Even though the current probe output is AC, there are instances where the user wishes to orient the transducer to get proper polarity at the output terminals (e.g., active power measurements). This is done by installing the transducer around the conductor with the molded-in arrow on the latch (see Fig. 2) pointing to the direction of conventional current flow.
- Conventional current flow is defined as current flowing from the positive to the negative potential. When a three-phase plant is under test, the correspondence must be respected between the voltage probe of the measuring instrument connected and the clamp kupima awamu sawa.
UFUNGASHAJI WA KIFUNGO
- Hazardous potentials may exist in the proximity of the desired current measurements. Use locally approved safety procedures when working close to hazardous potentials
- It is recommended not to install the clamp karibu na basi moja kwa moja ambalo liko katika uwezekano wa hatari. Ikiwa usakinishaji hauwezekani wakati basi imezimwa au nguvu imezimwa, kila wakati tumia glavu zinazofaa na/au vifaa vilivyoidhinishwa kufanya kazi karibu na uwezekano wa hatari wakati wa kusakinisha HTFLEX33e karibu na uwezo huu.
- It should also be noted that the current probes would produce twice the output voltage ikiwa unafunga transducers karibu na waendeshaji mara mbili
- Hakikisha clamp imewekwa kwa usahihi. Ufungaji usio sahihi wa clamp can affect the accuracy of measurement, and this may be influenced by the presence of external wires or other sources of electromagnetic fields
- Clamp must not wrap the wire tightly. The inner diameter of the clamp must always exceed that of the conductor.
Ili kufunga clamp, follow the steps:
- Wrap the coil around the conductor, joining the two ends of the head by respecting the arrow on the rear part of the closing device (see Fig. 2), which indicates the direction of the current that, by convention, is from the generator to the load
- Fix the closure by rotating the ring clockwise as shown below.
- Turn the ring counterclockwise and remove the two ends of the head to open the clamp.
MATENGENEZO
- TAHADHARI
- Make sure the current probe, as well as the output cable, is clean before installing it around the conductor. If no, the contaminants on them may provide a conductive path for a high-voltage kuvunjika
- Check the transducer and output cables for cuts and abrasions. The transducer should not be used if damaged
- Preventive maintenance primarily consists of cleaning the transducers and cables to prevent surface contamination.
- KUSAFISHA
- Use a mild detergent and water to clean the transducers and cables.
- Remove the detergent with clean water, then wipe dry with a clean cloth
- The use of solvents as cleaners is not recommended unless thoroughly tested and found harmless to all surfaces and parts. Do not drop the HTFLEX33e transducers or the electronics package into water or other fluids.
- MWISHO WA MAISHA
- TAHADHARI: this symbol indicates that the accessories and their parts shall be subject to a separate collection and correct disposal.
