Product Description

 

DNY-H Multifunctional Electricity Inspection Instrument/Power Quality Analyzer

Overview

The Multifunctional Electricity Inspection Instrument is a high-precision testing device independently developed by our company, integrating electrical parameter measurement, energy meter verification, and wiring judgment. Equipped with high-precision, highly linear voltage transformers and clamp-type current transformers, the instrument ensures exceptional measurement accuracy for various parameters while facilitating on-site wiring without disconnecting current circuits.

Featuring a large-color LCD screen with a fully Chinese graphical interface and multi-parameter display, the device offers user-friendly interaction. Vector diagrams and wiring judgment provide reliable verification for circuit correctness. The conductive silicone rubber keyboard ensures tactile operation, combining simplicity with ease of learning. A built-in large-capacity non-volatile memory stores up to 1,000 sets of on-site calibration data, which can be uploaded to computers via backend management software for digitized administration.

Housed in an ergonomic molded plastic casing, the instrument is compact and practical for field testing. It supports both desktop use (with a foldable rear stand) and handheld operation (with an optional strap for stability).

Features
1.Integrates energy meter calibration, electrical parameter testing, and power quality analysis (waveform distortion, voltage fluctuations, and three-phase imbalance).
2.Measures comprehensive errors of metering devices under live-load conditions without circuit interruption or equipment dismantling.
3.Precisely measures voltage, current, active/reactive power, phase angle, power factor, and frequency to calculate measurement errors.
4.Displays voltage/current vector diagrams for wiring validation; auto-identifies 48 wiring modes in three-phase three-wire systems and calculates corrective electricity values.
5.Clamp-type transformers enable safe current measurement without circuit disconnection.
6.Calibrates voltage/current/power/phase meters and single/three-phase (1A/5A) active/reactive energy meters.
7.Supports optical, manual, and pulse-based energy meter calibration.
8.Analyzes power quality: frequency/voltage deviation, voltage fluctuation, unbalance, and harmonics.
9.Displays single/three-phase voltage/current waveforms simultaneously.
10.Monitors load fluctuations and records parameters (voltage, current, power, frequency, phase).
11.Tracks power equipment adjustments and operational dynamics for troubleshooting.
12.Evaluates dynamic parameters of compensation/filtering devices quantitatively.
13.Built-in perpetual calendar/clock; stores and uploads data via serial port for PC management.
14.Portable design for field or lab use as a standard metering device.
