A good reliable megger that we have pretty much made our go too when buying new is a Fluke 1507. I like the 50-1000 VDC ranges. 500-650 price range, below that you can get one for 100-200 but I cannot say much about them.

Hit Amazon up.

The insulation resistance testers we use at work are all Megger. We don't do any residential work so can't comment on how our equipment would be for that. Everyone has a 1kV Megger MIT420. Goes up to 200G, PI and DAR tests, does it all pretty much for what we need on 600V switchgear, nice and compact. The other one that we use is the 5kV Megger MIT525-US, few guys have that one brand new, and then a bunch that are 5-10 years old. They are simple to use, and they display leakage current which has saved us from hauling the dc highpot around on a few occasions. If you are looking to get one for yourself, I have no idea how the prices compare to other brands. Just what our company uses, so when I need to megger bus, cables, breakers, whatever the case may be, that's what I'm handed.

We went through maybe 6 MIT meggers, I forget the actual model number. Had some other issues with some of their test equipment, I am pretty much done with AVO Megger test equipment. I was a Megger guy for better than 35 years.

I am partial to AMEC...I have a cheap 1kv megger and an expensive 15kv one
I have never used AEMC equipment other than their 2-3-4 point Earth/Ground Resistance testers. But they seem to sell a lot of stuff.

Expensive and 15kv are one in the same there are no inexpensive 15 KV's that I know of.

That is a piss off :censored: ! I could see switching brands blowing through 6 of those meters, they don't exactly cost 50 bucks to replace. You got me thinking about meggering now damn it, like I don't spend enough time already doing it at work :laughing: Actually I am mistaken about the 5kV insulation resistance testers, the few brand new fancy ones are Megger, the older ones are Hioki 3455 Insulation HiTester (great units). The only reason I can rhyme off the model numbers and names, last Friday had to write them all down with serial numbers, calibration dates, UL/CSA # and all that fun stuff for customer documentation :whistling2:. The rest of the year it's just 'grab the megger'!

Based on Big John's recommendation to someone else here on ET, I bought a BK Precision 307A for the actual low voltage testing that we do in house. It has served well so far. For our medium voltage testing and anything involving NETA type testing, an outside contractor is brought in.

We have a Fluke 1550. 5kV, has a timer, shows leakage current, does PI and DAR.

Can't complain other than it's kinda bulky, but at the end of the day it's basically a lead acid battery witha screen on it, so you get what you get i guess.

Ideal 61-795. I bought it on here because it was cheap and I only use it a few times a year for troubleshooting.
It serves my purposes very well and I am quite please with it.

I have a BK Precision 307A. It's pretty basic, and not very expensive. It's an analog model (which I like a lot), it's not very fancy, but it'll certainly let you know if it's safe to energize a circuit or not.

It has 250, 500 and 1000 volt ranges. Really easy to use.

I've had mine for several years, no issues. I paid around $200 for it.

In fact, I used it last Saturday to find a bad 200 amp explosion-proof pin and sleeve connector. A 150 amp breaker on a 600 volt system tripped, and everything was clear using a basic ohmmeter. But the megger showed a fault on all 3 phases.

Actually, if I can, I megger just about everything before I close it in.

I'd throw all that electronica away for this>

~CS~
Not me and I own a few of those, at one time that is all we had. The ability to do digital readings, not hand cranking, timed test.

Crank that for 10 minutes each for a 3 wire feeder.

I use a 1587 regularly, but I believe the 1507 has a higher voltage setting available. The 1587 is a multimeter with temp and the ability to work with a clamp meter accessory, which suits my purposes and I've been happy with it.
