WT-T300

T300 Multi-functional On-site Inspection & Anti-tampering Instrument

This product is designed for error detection, wiring inspection, and anti-tampering audits of single-phase and three-phase energy meters and metering systems. An optional wireless high-voltage current clamp is available to perform inspections on field high-voltage metering systems of 35kV and below. The Instrument utilizes a split-unit design, enabling wireless measurement of electrical parameters, which effectively enhances operator safety.

Product Functions

  • Comprehensive Parameter Measurement: Measures voltage, current, power (P, Q, S), phase angle, frequency, and power factor.
  • Power Quality Analysis: Features 64th harmonic measurement and displays 6-channel waveforms to analyze line power quality.
  • Error Verification: Calibrates basic errors of single/three-phase meters. With configurable transformer ratios, it performs total error verification for metering systems.
  • Register Verification: Includes a constant check function for meter pulses.
  • Anti-Tampering Audit: Supports infrared and RS485 communication to read real-time meter data and analyze fraudulent power usage behavior.
  • Phase Identification & Wiring Analysis: When configured with wireless clamps or wireless samplers, it performs phase verification tests. It supports manual or automatic detection of incorrect wiring and generates vector diagrams.
  • CT Ratio Test: Measures high/low voltage CT ratios and phase displacement (angle error).

Product Features

  • Low-Current Detection: Capable of performing wiring inspections even at a minimum current of 5mA.
  • Multimedia Evidence Collection: Supports on-site photography, audio recording, video recording, and barcode scanning to minimize disputes with utility customers.
  • Auto-Clamp Identification: Automatically recognizes clamp types without manual range switching, preventing human error.
  • Man-Machine Separation: Controlled via a tablet, allowing for dual-screen display and physical separation from the high-voltage source to ensure safety. Supports simultaneous connection of multiple tablets.
  • Management Software: Includes PC management software for uploading, downloading, and printing field data, providing valid evidence for audits.
  • Flexible Current Clamps: Optional Rogowski coils (flexible clamps) for current measurement in narrow spaces like busbar compartments.
  • Wireless Integration: Supports the integration of wireless clamps for remote measurement.
