Introduction

Zinc oxide arrester tester is specifically designed to detect internal electrical defects of power system with 10KV and below using MOA valve clearance indirect contact and to measure leakage current under MOA DC reference voltage (U1mA) and 0.75 U1mA. The instrument integrates high-voltage DC power supply, measurement and control system. All components are concentrated in a single chassis, with small size, light weight. It is a must for power system and zinc oxide arrester tester manufacturer field test.

Technical Parameters

• Measuring range: voltage :0～30KV(DC) current: 0～1000µA
• Measuring accuracy: voltage 1%
• Altitude：﹤1000m
• Ambient temperature：0～40℃
• Power source voltage：220v±10%
• Relative humidity：at 25℃ ≤85%
• Power source frequency：50±1Hz

Introduction

Compact lightning counter tester is specially designed according to needs of power consumer. The tester is fabulous, portable and popular, could be replacement of traditional measuring device.

Technical Parameters

• Dimension: ø 36х375，head ǿ50х100
• Weight:420g
• Ni-H rechargeable battery pack, completely avoid battery replacement or damage caused by battery fluid leakage.
• Output voltage：800～1000V
• Power switch is located in between the body and head, rotated 90 degrees in any direction. When heard “rattle” sound after that power is on, otherwise power is off. Before use insert grounding wire in the rear. The green light will be on when connected to power. When the red light is on (about 3 to 5 seconds later), test the lightning counter through flexible conductive rod. No need to turn off the power to repeatedly test (during each charge conductive rod should leave the test object).

Introduction

The instrument is used to test specific parameters on field or in laboratory for zinc oxide arrester. It is widely used in on-site inspection (live testing) and laboratory tests (power cut overhauling). It is in line with national standards in DL474.5-92 On-site Insulation Test Implementation Guidelines- Arrester Test.
