Product Details

DC Separated Net Insulation Monitor WD-ZBMΩ ABS Plastic Shell Housing

1. Product Introduction:

This type of meters are analog electric measuring instruments, widely used for measuring AC/DC current, voltage, frequency, power,power factor, insulation resistance and synchronous indicating in AC/DC transmitting & distributing power system, switchboard, other electric & non-electric instruments.

Our 96*96mm & 72*72mm squre meter, and 110*110mm, 80*80mm are round type meter improved in structure, material, seals according to environmental conditions & demands in marine industry, which let our meter have the ability of not only advanced technology, reasonable structure, good quality, but also good appearance, light weight, anti-mechanical force and different climate.

4. The Installation:

Unless specified, the meter is usually installed in a vertical position. Other installation positions such as horizontal and inclined position can be installed according to the customer’s requirements. The corresponding level of accuracy is only valid to the regulated installation position. The meter has two kinds of instruction angles: right angle 90°and wide angle 240°.

5. Accuracy Level:

The WD series of pointer meter: AC and DC voltmeter and ammeter to the level of 1.5 or 2.5, power meter to the level of 2.5, frequency meter to the level of 1.5, and power factor meter to the level of 2.5.

6. Using Instructions:

Monitoring the insulation resistance of ungrounded power network. When insulation resistance is lower than the preset value, alarm release.

Based on principle method, the net insulation monitor can be divided into following catagories:

a) . Monitor with measuring system, called integrated net insulation monitor, can be customized with self-dection function.

Explaination as follows:

"Monitor" mode: Ordinary monitoring, monitor works as normal;

"Suspend" mode: Invalid, monitor does not check with the insulation resistance of circuit, and pointer come to ∞;

"Test" mode: Self-detection. Monitor does not check with the insulation resistance of circuit, pointer come to 0, alarm LED lit, release activated.

b). Monitor and measuring system are separated, called separated net insulation monitor.

c). Monitor the insulation resistance of two ungrounded power network at the same time, using integrated double circuit net insulation monitor.
