DRANETZ
Frequently asked questions
Common questions about DRANETZ from 3G Electric.
What safety ratings are available for Dranetz flexible current probes?
Dranetz flexible current probes are available with CAT III 1000V and CAT IV 600V safety ratings. For example, the DRANFLEX3000XLB24 and DRANFLEX6000XLB24 have CAT III 1000V ratings, while the DRANFLEX6000XLB36 and DRANFLEX6000XLB48 carry CAT IV 600V ratings. These ratings indicate the probe's suitability for different measurement environments, with CAT IV covering installations closer to the utility supply. The safety rating is marked on the probe and should be matched to the measurement category of the circuit under test.
What is the jaw opening range for Dranetz clamp-on current probes?
Dranetz clamp-on current probes in the 3G Electric catalog have jaw openings of 0.59 inches and 15 inches. The 0.59-inch model (SKU 2TB94) is a clamp-on probe for AC current and AC voltage measurement with a CAT III 600V rating. The 15-inch model (SKU 4DZY3) is a clamp probe for AC current with a CAT IV 600V rating. These sizes accommodate different conductor diameters, from small wires to large busbars, without disconnecting the circuit.
What is the sampling rate of the Dranetz HDPQ power analyzer?
The Dranetz HDPQ-P-GAFLEX3KPKG power analyzer has a sampling rate of 512 samples per cycle. This four-phase digital analyzer is rated CAT III 1000V/CAT IV 600V and has an IP65 enclosure. The sampling rate determines the resolution for capturing waveform details and harmonics. The IP65 rating indicates protection against dust and water jets, making it suitable for use in industrial environments where exposure to contaminants may occur.
Are Dranetz current probes compatible with all Dranetz power analyzers?
Dranetz current probes use a proprietary connector type, so compatibility depends on the specific analyzer model. The probes listed, such as the DRANFLEX3000XLB36 and DRANFLEX6000XLB48, are designed for use with compatible Dranetz power quality instruments. Before ordering, verify the connector type and input specifications of your analyzer. 3G Electric provides product details including connector type and manufacturer part numbers to assist with matching probes to analyzers.
What is the difference between Dranetz flexible and clamp-on current probes?
Dranetz flexible current probes use a flexible Rogowski coil design, allowing them to wrap around large or irregularly shaped conductors. They are available with jaw openings from 7.5 to 15 inches and safety ratings up to CAT IV 600V. Clamp-on current probes use a rigid jaw that opens to clamp around a conductor; the models in this catalog have jaw openings of 0.59 inches and 15 inches. Both types provide non-invasive AC current measurement, but flexible probes are often chosen for tight spaces or large busbars where a rigid clamp may not fit.
What applications are Dranetz power analyzers used for?
Dranetz power analyzers are used for monitoring and analyzing power quality on electrical systems. Typical applications include load profiling, harmonic analysis, voltage event recording, and energy audits. The HDPQ series, with four-phase capability and 512 samples per cycle, supports detailed waveform capture. These instruments are used in industrial plants, commercial buildings, and utility substations to identify issues such as voltage sags, swells, transients, and harmonic distortion. The IP65 enclosure allows use in harsh environments.
