LDP-5

Product catalog summary

Applications

Detection of dangerous partial discharges (PD).
Differential measurement mode for PD fault location.
Diagnostics on high voltage apparatus in the field, such as cable sealing ends, joints, surge arrestors, power transformers, voltage transformers, and electrical machines.
Evaluation of PD behavior in low voltage components like opto-couplers, capacitors, transformers, and motors.

Advantages

Battery-powered portable device suitable for both on-site and laboratory PD diagnosis.
Cost-effective PD detector for research and development purposes.

Description

Detects electromagnetic transients of PD events.
Measures the PD quantity "apparent charge".
Features exchangeable capacitive and inductive sensors.
Potential-free signal transmission via fiber optic link.
Includes noise reduction mode.
Measuring sensitivity for directly injected charge pulses: 0.05 pC.
Gain steps available: 1, 2, 5, 10.
Vernier range: 1:5.
Output (CHARGE) at full load: triangular, positive pulse shape with a magnitude of approximately 4 V, rise time of less than 2 µs, and duration of approximately 50 µs. Noise level is less than 0.2 V.
Pulse resolution performance for superposition error less than 30% with a pulse repetition rate of less than 100 kHz and double pulse distance greater than 2 µs.
Powered by 8 Mignon batteries (LR6).
Dimensions: 220 × 60 × 100 mm.
Weight: approximately 1 kg.

Accessories

LDC-5 - Calibrator for external calibration of the PD measuring circuit in pC of apparent charge up to 500 pC.
LDA-5/U4 - UHF-Converter.
