Product Overview

Core Product Competitive Advantages

1. Dual‑mode AC & DC high‑voltage output
   One instrument delivers 0‑10 kV adjustable AC and DC high‑voltage outputs. Operators swiftly toggle between AC and DC test modes to satisfy different dielectric‑testing workflows for diverse cable‑insulation materials.
2. Multi‑level selectable breakdown trip‑current
   6‑grade breakdown‑current threshold options:0.5 mA, 1 mA, 3 mA, 5 mA, 10 mA, 20 mA. The equipment automatically cuts‑off high‑voltage output once specimen breakdown leakage‑current exceeds preset value, protecting both test sample and internal instrument circuits from damage.
3. Programmable timed withstand‑voltage function
   Test holding‑time adjustable from 1‑99 minutes. After starting the test, the unit maintains target high‑voltage automatically; it will stop output and trigger alarm when timing completes or breakdown event occurs, lowering manual‑operation workload for batch‑sample testing.
4. Intuitive analogue‑meter read‑out & compact benchtop build
   Clear analogue panel meters display real‑time voltage and leakage‑current variation. Front‑panel rotary knobs simplify voltage‑level and parameter setup. Portable metal‑enclosed cabinet occupies little bench‑top footprint, easy for lab‑station or production‑line deployment.
5. Built‑in multi‑layer electrical‑safety safeguards
   High‑voltage‑output warning marking, reliable grounding terminal and internal over‑current‑protection circuit reduce operator‑exposure‑risks during high‑voltage‑testing procedures, complying with basic lab‑high‑voltage‑operation‑safety‑requirements.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation
   Place tester on insulated stable work‑bench. Secure protective earth‑ground connection. Hook‑up mains‑power‑supply. Confirm high‑voltage output terminal is disconnected from sample. Select AC / DC working‑mode, set breakdown‑current gear and configure withstand holding‑time according to cable‑spec requirements.
2. Specimen Connection
   Switch‑off power supply before wiring. Connect test‑cable specimen between high‑voltage output terminal and ground return terminal. Double‑check wiring to prevent short‑circuit risk; keep operators away from high‑voltage exposed nodes during running phase.
3. Start Withstand‑Voltage Test
   Power‑on instrument, slowly ramp‑up output voltage to target‑value. Timing function activates automatically. Instrument keeps applying high‑voltage stress to cable‑insulation layer. Observe meter pointer for abnormal leakage‑current jump.
4. Breakdown Judgement & Test Completion
   If specimen insulation breaks down, leakage‑current exceeds threshold, the tester will immediately shut‑down high‑voltage and send alarm prompt. When pre‑set holding‑time expires without breakdown event, test passes. Manually lower output‑voltage down to zero.
5. Post‑Test Tidying
   Fully discharge capacitive‑type cable‑specimens. Disconnect test‑sample wiring. Power‑off main‑unit. Regularly inspect high‑voltage‑cable insulation condition and cabinet‑grounding‑reliability.
