NDBL-IV zinc oxide arrester live tester (Single phase test)
basic information
Detailed parameters
Reference standard: DL474.5-92, DL/T987-2005.
Features:
● It is suitable for use in lightning arresters with power, power outage or laboratory;
● The current and voltage sensors are completely isolated and safe.
● Three-phase test A, B, C three-phase zinc oxide arrester can be saved as a set of test data;
● Anti-interference calculation can be performed to compensate for the deviation of phase A of two phases A and C;
● The instrument only has weak current inside, and the voltage does not exceed 12V. The charging state can also work.
