MOEORW-DY5 Adjustable Low-Voltage Electroscope Starting Voltage Test Box Send email to us

1. Full Compliance with Utility Safety Standards

Designed to meet the latest utility safety tools testing regulations (DL/T 1476-2023 and DL/T 740-2014), the MOEORW-WDY5 provides legally defensible test results that are fully traceable to national metrology standards. For 0.4kV low voltage electroscope verification, the pass/fail threshold is clearly defined: starting voltage must fall between 60V and 160V. The tester directly supports this determination, eliminating guesswork.

2. True Pure Sine Wave Output

Unlike low-cost square-wave generators, the MOEORW-WDY5 delivers a true pure sine wave voltage test source at 50Hz. This is critical because electroscope internal detection circuits are calibrated for real grid waveforms. Non-sinusoidal sources can produce false readings-our pure sine wave ensures test results match real-world grid conditions.

3. Smooth 0-220V Manual Adjustment

The manual control knob provides smooth, continuous adjustment across the full 0-220V adjustable AC voltage source range. This allows operators to slowly increase voltage as required by test procedures, precisely capturing the moment when the electroscope first emits a stable audible and visual alarm. The long-travel potentiometer design ensures repeatable and reliable readings across multiple tests.

4. Built-in Isolation Transformer for Safety

The built-in isolation transformer provides complete electrical separation between input and output circuits. This design protects operators from accidental shock and suppresses harmonics from the AC line, ensuring digital voltage readings are accurate and stable.

5. Integrated Portable Enclosure

Housed in an insulating, flame-retardant carry case, the instrument integrates all necessary components into a single portable unit. It is equally suitable for fixed laboratory use and on-site field testing, reducing setup time by over 50% compared to bulky transformer systems.

6. Mandatory Grounding Protection

A dedicated grounding terminal is provided and clearly marked. The test procedure requires a secure earth ground connection before operation, enforcing safe work practices and reducing the risk of electric shock during testing.
