Re: MOV`s voltage/resistance curve

Hi Finn.

Here is the data I have got from Panasonic datasheets:

Voltage -at- 1 mA : 1800V (1700 - 1980V)
Maximum voltage: 1000 VACrms or 1465 VDC
Clamping voltage (max): 2970V -at- 5 0A
Rated power: 0.6 W
Max. energy: 510J (10/1000us) , 360J (2ms)
MAx. peak current (8/20us): 5000A (1 time) , 4500A (2 times)
Max. capacitance: 120 pF -at- 1 kHz

All the curves given are voltage vs. current or surge current vs. pulse width.
Nothing else is given by Panasonic.

Regards

P.S. 10/1000us and similar are standard pulses: 10 us rise time, 1000 us decay
time.

I am going to use 4 MOT`s in series for my next coil. The secondaries
are 2020V each, so that they will yield 4040 Vrms on each side of the
grounded center.

To protect them against overvoltage, I will use gaps and MOV`s.

I have bought some Panasonic ERZV 14 D 182 which have these ratings:


Max. continious Voltage: 1410 Vrms/1000VDC

Max clamp V: 2970 V -at- 50Amps

Voltage at 1mA: 1800

With such a big difference btwn. significant voltages, I am wondering
how many I should stick in each leg.

A voltage/resistance curve would be nice.
