关于此计算器
How this is calculated
The tool compares your measured test values with the limits for the circuit. Tick the tests you did. The tool checks only those.
- Insulation resistance. The tool reads the minimum and the test voltage from AS/NZS 3000 Cl 8.3.6. It also reads the AS/NZS 3017:2022 figure from Cl 4.5.4.
- Earth continuity. It reads the limit for the earth conductor size from Table 8.2. It also reads the limit at 80 % of the rated current. AS/NZS 3017:2022 Cl 4.4.4 gives the main earth and bonding limit.
- Loop impedance. It reads the maximum Zs for the device and disconnection time from Table 8.1.
- RCD trip time. It compares your measured time with the limit for the rated residual current.
- Polarity. You confirm polarity and connections. The tool does not measure them. It points at AS/NZS 3017:2022 Cl 4.6.4.
- Verdict. The result passes only when every test you ticked passes.
Worked example
- Lighting circuit, 2.5 mm² on a 20 A B curve breaker. Insulation is 50 MΩ against a 1 MΩ minimum. Earth continuity is 0.3 Ω against a 0.9 Ω maximum. Zs is 1.2 Ω against a 2.9 Ω maximum. The verification passes.
Limits
The tool does not take your readings. It does not correct a loop reading for temperature. A pass here is not a certificate. A competent person signs the verification. Use the loop impedance calculator to predict Zs before the test.

问题
结果仅供设计参考。请依据现行标准核对。
测试结果工具有什么作用?
工具将您在现场测得的数值与 AS/NZS 3000 Section 8 的验收限值进行比较。它检查绝缘电阻、接地连续性、回路阻抗和 RCD 动作时间。每项检查均报告合格或不合格。总体结论为合格、不合格或未验证。
最小绝缘电阻是多少?
Clause 8.3.6.3 规定,直流 500 V 时为 1 MΩ。带护套的加热元件为 0.01 MΩ,RCD 功能接地连接为 0.05 MΩ。若存在浪涌保护或电子设备,测试电压可降至 250 V。
它采用哪个回路阻抗限值?
工具依据 AS/NZS 3000:2018 Table 8.1,按保护装置类型、额定值和切断时间,列出表中的最大 Zs。工具还会报告 Table 8.2 中在额定电流 80% 时的最大 Rphe 和 Re,适用于无负荷测试。
为何工具显示“未验证”?
您所要求的测试无法进行。Table 8.1 中没有与该保护装置额定值对应的行,或未选择任何测试。对于未进行的检查,本工具不会报告通过。请更改额定值,或使用回路阻抗工具。
AS/NZS 3017:2022 适用于哪些情况?
AS/NZS 3017:2022 给出各项检验测试的方法。其绝缘和总接地限值与 Section 8 一致,因此本工具两者均予引用。其回路阻抗表格保留一位小数,因此本工具的 Zs 采用 Table 8.1。
计算示例
- A test sheet for a house boardA test sheet for a six-circuit New Zealand house board, with the tests in the AS/NZS 3017 order and the limit for each reading, then the Australian sheet.
- Reading the wiring in an older houseA 1970s New Zealand house with yellow actives, a green earth and a black neutral. What each colour can be, what may stay, and how to sleeve new terminations.
背景
- The order of verification testsWhy AS/NZS 3017 tests earth continuity before insulation and loop impedance before RCDs, which circuits take which test, and where each limit comes from.
- Testing to Section 8: what each test provesThe Section 8 test sequence, what each test shows, and how a calculated earth fault loop impedance compares with the value a tester reads on site.
