Ngā reiti hapa papa hiko, ngā harmonics i te neutral, me ngā nama kei muri i te tapanga arc flash.
- 4 meneti te pānuiArc flash basicsArcing current, incident energy, boundary and working distance explained, with three engine runs that show clearing time beating fault current every time.
- 4 meneti te pānuiHarmonics and neutral sizingWhy third harmonic current adds in the neutral of a four-wire circuit, what the 0.86 factor does, and how to apply it by hand to a cable size result.
- 4 meneti te pānuiIndustrial switchboards: fault rating, form, IPWhat the three ratings on an industrial switchboard or motor control centre mean, how each one is chosen, and which AmpSize tools feed the numbers behind them.
- 3 meneti te pānuiProspective fault current at a boardHow the fault current at a board comes from the source impedance and the submain, why the cold cable gives the maximum, and what to compare it with.
Ngā tātaitai e whakamahia ana e ēnei aratohu
- Tātaitai Arc FlashTātaungia te pūngao o tētahi arc flash me tōna karaehe PPE.
- Tātaitai fault rating tauraTirohia mēnā ka ū tētahi kaikawe ki te iahiko hapa.
- Tātaitai IDMT gradingWhakatakotoria ngā kōpiko tuku o ngā relay overcurrent wā-whakahuri.
- Tātaitai TransformerTātaitia te iahiko uta katoa me te impedance o te transformer.
- Tātaitai rahi tauraKimihia te rahi taura iti rawa e pass ana i ia arotake.
- Tātaitai Power Wāhanga ToruHurihia i waenga i te power, te iahiko, te voltage me te power factor.
- Tātaitai mōtāKimihia te iahiko uta katoa mōtā, te iahiko tīmata me te torque.
- Tātaitai Iahiko Uta KatoaTātaitia te iahiko uta katoa mai i te mana, te voltage me te wāhanga.
- Tātaitai taumata hapaTe iahiko hapa ka puta pea i tētahi papa mai i tōna puna.
