An overview,

Zy-y01c HIGH and low pressure CT ratio tester (hereinafter referred to as the tester) is launched by our company based on years of experience in producing intelligent instruments to meet the needs of users on site. It can measure the high voltage primary current and low voltage secondary current of the high voltage metering device of the system 35KV and below without disconnecting wires and continuous electricity on site, and calculate the variable ratio and variable ratio error.

Two, technical indicators

2.1 Barrier-free transmission distance of clamp meter information: 500 m;

2.2 Primary current: input of high voltage clamp meter is 0 ~ 300A;

Low voltage clamp meter input 50A, 100A, 500A, 1000A,

1500 A, 2000 A (optional according to user requirements)

2.3 Secondary current: the input of the tongs transformer is 0 ~ 5A;

2.4 Measurement accuracy

2.4.1 High voltage current: 0.2a ~ 300A ± (0.5%× reading +1 word);

2.4.2 Low voltage current: 0.05a ~ 5A ± (0.5%× reading +1 word);

2.4.3 Ratio and error: 1.0%;

2.5 Variable ratio measurement range: 1 ~ 500;

2.6 Operating temperature: -10℃ ~ +50℃;

2.7 Power consumption: high voltage clamp meter about 0.5W, hand-held terminal about 2W;

2.8 Overall size (mm) : 420*320*105 (integrated packaging);

2.9 Preheating time: 1 minute.
