I. Introduction
1. Principle of the meter
HT2670
Portable Megger
consists of medium and large
scale integrated circuit with high output power and high
short-circuit current value features. The output voltage is up to
four grades. The built-in battery served as power supply
become high DC voltage by DC/DC transformation, which
goes from E pole to L pole via the object being tested. By this
way, it produces a current from pole E to pole L, which
converted by I/V and computed by the divider. The value of
insulation resistance will display on the LCD finally.
2. Block Diagram of Circuit
As shown in the following diagram:
3. Applications
The meter is essential and common device in power
industry, post and telecommunications, communications,
mechanical and electrical installation and maintenance and
industrial sector or corporate sector using electric power as
